The occurrence class is an attribute of an occurrence that identifies the type of occurrence. The occurrence class indicates if the occurrence is a declaration, a reference, or one of the other classes in the list that follows. If the occurrence class is a declaration or reference, the occurrence class indicates what type of declaration or reference it is. The format for the occurrence class attribute is as follows: OCCURRENCE=(keyword[,keyword...]) The occurrence class can be one of the following keywords: Declarations o PRIMARY - most significant declaration o ASSOCIATED - associated declaration o DECLARATION - primary or associated References o READ, FETCH - fetch of a symbol value o WRITE, STORE - assignment of a symbol value o ADDRESS, POINTER - reference to the location of a symbol o CALL - call to a routine or macro o COMMAND_LINE - command line file reference o INCLUDE - source file include referenece o PRECOMPILED - precompiled file include referenece o OTHER - any other kind of reference (such as a macro expansion or use of a constant) o REFERENCE - any of the preceding values o BASE - Any base class of a C++ class o FRIEND - Any friend of a C++ class o MEMBER - Any member of a C++ class o SPEPARATE - Any Ada package or sub-program unit defined as SEPARATE o WITH - Any WITH of an Ada package or sub-program unit Other Occurrence Classes o EXPLICIT - explicitly declared o IMPLICIT - implicitly declared o VISIBLE - occurrence appears in the source o HIDDEN - occurrence does not appear in the source o COMPILATION_UNIT - the declaration that contains all occurrences in a particular compilation unit o LIMITED - Any Ada limited private type o PRIVATE - Any private C++ objects, or Ada private type o PROTECTED - Any protected c++ object o PUBLIC - Any public C++ object o VIRTUAL - Any virtual C++ object The previous keywords are SCA terms. For information on corresponding language-specific terms, request help for the appropriate language table (for example, FORTRAN_ATTRIBUTES_TABLE) under the Getting_Started help topic. An example using the occurrence class attribute follows: FIND OCCURRENCE=PRIMARY This query finds all PRIMARY occurrences of declarations.
