All Known Implementing Classes:

AccessSymbol, DerefSymbol, IPPointsToAnalysis.AbstractLocation, NestedDeclarator, Procedure, ProcedureDeclarator, PseudoSymbol, VariableDeclarator

Method Detail

getTypeSpecifiers

java.util.List getTypeSpecifiers()

Returns a list of type specifiers.

Returns:

the list of type specifiers.

getArraySpecifiers

java.util.List getArraySpecifiers()

Returns a list of array specifiers.

Returns:

the list of array specifiers.

getSymbolName

java.lang.String getSymbolName()

Returns the name of the symbol.

Returns:

the name of the symbol.

setName

void setName(java.lang.String name)

Modify the name of the symbol. This method effectively renames all the identifiers constructed from the symbol object. Pass writers should be cautious when renaming global names since the effective scope of this operation is within a translation unit; extern variables and procedure names are not automatically handled.

Parameters:

name - the new name of the symbol.

getDeclaration

Declaration getDeclaration()

Returns the parent declaration containing the symbol object. The return value is searched from the internal look-up table. Depending on the type of the symbol, this method may return the symbol object itself, or null if the symbol object does not exist in the IR.

Returns:

the parent declaration.
