Topic: Instantiation


  
 [No title]
CONFIGURATION configuration_name The semantics of a component instantiation whose instantiated unit is a component is the same as in VHDL 87 (i.e., the double- nested block equivalence is described in LRM 9.6.1).
The semantics of a component instantiation whose instantiated unit is an entity or configuration is similar with the one important exception that it is equivalent to a single nested block rather than a pair of nested blocks.
Instantiations whose instantiated unit is an entity or configuration may not be "re-configured" with a configuration specification or with a component configuration containing an explicit binding indication.

 PEP 317 -- Eliminate Implicit Exception Instantiation
When instantiation is implicit, it is not obvious when it occurs, for example, whether it occurs when the exception is raised or when it is caught.
Code which instantiates explicitly would not be affected, since the run-time checks necessary to determine whether to issue a warning are exactly those which are needed to determine whether to instantiate implicitly in the first place.
Code which instantiates implicitly would incur a large cost: timing trials indicate that issuing a warning (whether it is suppressed or not) takes about five times more time than simply instantiating, raising, and catching an exception.

 Inferred Type Instantiation for GJ   (Site not responding. Last check: 2007-10-19)
The task of type instantiation is to substitute types for formal type parameters in applications of polymorphic methods.
Instantiating these parameters automatically considerably reduces clutter in program code that applies polymorphic functions.
This is a good indication that the new type inference scheme is in practice at least as good as the previous one.

 An Introduction to GCC - Explicit template instantiation
These instantiations are typically placed in a separate source file, which is then compiled to make an object file containing all the template functions required by a program.
The disadvantage of explicit instantiation is that it is necessary to know which template types are needed by the program.
Any missing template instantiations can be determined at link time, however, and added to the list of explicit instantiations, by noting which functions are undefined.

 Using the GNU Compiler Collection (GCC)
Borland C++ solved the template instantiation problem by adding the code equivalent of common blocks to their linker; the compiler emits template instances in each translation unit that uses them, and the linker collapses them together.
A future version of g++ will support a hybrid model whereby the compiler will emit any instantiations for which the template definition is included in the compile, and store template definitions and instantiation context information into the object file for the rest.
For library code, if you want the library to provide all of the template instantiations it needs, just try to link all of its object files together; the link will fail, but cause the instantiations to be generated as a side effect.

 rfc 3269 reference for Network Programming in .NET with C# & Visual Basic .NET (VB.NET)
The purpose of these guidelines is to ensure that any building block and protocol instantiation definitions produced contain sufficient information to fully explain their operation and use.
In addition these guidelines provide directions to specify modular and clearly defined RMT building blocks and protocol instantiations that can be refined and augmented to safely create new protocols for use in new scenarios for which any existing protocols were not designed.
Whether or not a particular Reliable Multicast Transport protocol instantiation becomes sufficiently popular to warrant its own protocol number is an issue which will be deferred until such time that the protocol has been sufficiently widely deployed and understood.

 Component Instantiation Statements
Similar to process code the component instantiation statements are transformed into corresponding C++ statements.
They reside in the constructor code of a corresponding architecture class and indirectly call constructors of the component to be instantiated.
Besides executing the constructor of the new component another important task of the instantiation code is to connect the signals of the current component (also called actual signals; see Section 3.1 item 1) with the interface signals (ports) of the new component (also called formal ports/signals; see Section 3.1 item 2).

 Generic Instantiation
Implicit declarations are also copied, and a name that denotes an implicit declaration in the generic denotes the corresponding copy in the instance.
However, for a type declared within the visible part of the generic, a whole new set of primitive subprograms is implicitly declared for use outside the instance, and may differ from the copied set if the properties of the type in some way depend on the properties of some actual type specified in the instantiation.
Recursive generic instantiation is not allowed in the following sense: if a given generic unit includes an instantiation of a second generic unit, then the instance generated by this instantiation shall not include an instance of the first generic unit (whether this instance is generated directly, or indirectly by intermediate instantiations).

 4.6.7 A second instantiation   (Site not responding. Last check: 2007-10-19)
A second, more realistic, instantiation of the hierarchy will be briefly presented.
This instantiation will be supported by a package called DailyAppointment whose extendible type, DailyAppointments, will allow a date and details of an appointment to be modelled.
Having instantiated the hierarchy a demonstration test harness can be constructed using the same techniques as were used for the previous instantiation.

 metamodel.com - Instantiation = Generalization?
From the point of view of the meta-model, Person and Employee are instances of the meta-class Class and employedBy is an instantiation of the meta-class Association.
Instantiation and Generalisation are very similar as far as the results go.
Speaking in very general term an instantiation gives you more control over what a 'car' will look like, because you determine on the meta level which associations are allowed etc.

 Using mixtures of factor analyzers for segmentation and pose estimation   (Site not responding. Last check: 2007-10-19)
By using conditional mixtures of factor analyzers, it is possible to extract an explicit, compact representation of the instantiation parameters that describe the pose of each digit.
These instantiation parameters can then be used as the inputs to a higher level system that models the relationships between digits.
The same technique could be used to model individual digits as redundancies between the instantiation parameters of their parts.

 RFC 3269   (Site not responding. Last check: 2007-10-19)
Protocol instantiations have the ultimate responsibility of addressing security requirements, in conformance to RFC 2357.
The applicability statement's purpose is to frame the design space in which the fully realized protocol will operate and to thereby enable subsequent would-be RMT protocol designers to determine whether or not an existing protocol already meets their needs.
Protocol instantiation document authors are specifically reminded that RFC 2357 requires that any RMT protocol put forward for standardization with the IETF is required to protect the network in as much as is possible.

However, it is also believed that there is sufficient commonality between the various approaches that it should be possible to define a number of building blocks [RFC3048] from which the various RMT protocols can be constructed.
Security Considerations Protocol instantiations have the ultimate responsibility of addressing security requirements, in conformance to RFC 2357.
In recognition of the fact that protocols will evolve and that IP protocol numbers are a scarce resource, protocol instantiations MUST initially define packet formats for use over UDP [RFC768].

 CULTURAL CONSTRUCT + INSTANTIATION = CONSTRUCTED REALITY
Paper given at the symposium, Cultural Idea Systems: Logical Structures and The Logic of Instantiation, AAA Meetings, Washington DC, November 28 - Dec. 2, 2001 (D. Read and M. Leaf, organizers).
In this paper I suggest that such a paradigm is provided through making a distinction between formal models of the logic of cultural constructs and the logic of the instantiation of the symbolic/abstract elements of those cultural constructs.
An example illustrating this paradigm, based on the logic of a kinship terminology structure in comparison with the logic of the instantiation of a kinship terminology structure, will be discussed.

 instantiation - a Whatis.com definition   (Site not responding. Last check: 2007-10-19)
To instantiate is to create such an instance by, for example, defining one particular variation of object within a class, giving it a name, and locating it in some physical place.
2) In the object-oriented programming language, Java, the object that you instantiate from a class is, confusingly enough, called a class instead of an object.
In other words, using Java, you instantiate a class to create a specific class that is also an executable file you can run in a computer.

When an application registers, it does not specify the instantiation - rather this is returned by the CCC library such that it is unique for the specified
Which one it chooses should depend on to whom the message was addressed.

 Java Tip 67: Lazy instantiation   (Site not responding. Last check: 2007-10-19)
The policy of lazy instantiation illustrated above is fine for our examples, but later on you'll see how the design has to alter in the context of multiple threads.
The lazy approach to instantiating a Singleton is unnecessary in Java because of the way in which the Java runtime handles class loading and static instance variable initialization.
Using lazy instantiation for a concrete Singleton is not only unnecessary in Java, it's downright dangerous in the context of multithreaded applications.

 Using and Porting GNU CC - Template Instantiation   (Site not responding. Last check: 2007-10-19)
The AT&T C++ translator, Cfront, solved the template instantiation problem by creating the notion of a template repository, an automatically maintained place where template instances are stored.
g++ has extended the template instantiation syntax outlined in the Working Paper to allow forward declaration of explicit instantiations, explicit instantiation of members of template classes and instantiation of the compiler support data for a template class (i.e.
; this flag causes template instances to be emitted in the translation unit that implements the header where they are first instantiated, rather than the one which implements the file where the templates are defined.

 [HOL-CASL] Problems with instantiation   (Site not responding. Last check: 2007-10-19)

n = n * n"; %% instantiation by 0 or 1 %% direct by (res_inst_tac [("x","0")] exI 1); by (res_inst_tac [("x","1")] exI 1); %% or in 2 steps br exI 1; by (instantiate_tac [("n","0")]); by (instantiate_tac [("n","1")]); In all cases the tactics "res_inst_tac" and "instantiate_tac" hang up.
Is an explicit theory instantiation with concrete parameter the only or just the preffered way to handle the problem?

 Java Tip 67: Lazy instantiation
With lazy instantiation, a program refrains from creating certain resources until the resource is first needed -- freeing valuable memory space.
In this tip, we examine lazy instantiation techniques in Java class loading and object creation, and the special considerations required for Singleton patterns.
These two approaches illustrate the techniques of eager instantiation (load it in case it's needed) and lazy instantiation (wait until it's requested before you load it, as it may never be needed).
