The C# language has supported attributes from its very first release. These attributes was used to give run-time information and are not used by a preprocessor. Currently with source generators, you can use attributes to drive generation of additional code at compile-time.
Attribute values can be set-valued or atomic-valued. Set-valued attributes contain more than one atomic value. Examples are role and project. Atomic-valued attributes contain only one atomic value. Examples are clearance and sensitivity. Attributes can be compared to static values or to one another, thus enabling relation-based access control.
In computer science, the fetch-and-add (FAA) CPU instruction atomically increments the contents of a memory location by a specified value.. That is, fetch-and-add performs the following operation: increment the value at address x by a, where x is a memory location and a is some value, and return the original value at x.
An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such. For clarity, attributes should more correctly be considered metadata. An attribute is ...
Figure 1: Three processes accessing a shared resource (critical section) simultaneously.. Thread synchronization is defined as a mechanism which ensures that two or more concurrent processes or threads do not simultaneously execute some particular program segment known as critical section.
In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system.
Attribute-driven design [1] [2] (also called ADD or Attribute-driven design method) is a methodology to create software architectures that takes into account the quality attributes of the software. It was previously known as the Architecture Based Design Method (or ABD), but due to trademark issues the name was changed to Attribute-driven ...
Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate an attributed parse tree .
