getIntValue()

llvm::APSInt ComparisonCategoryInfo::ValueInfo::getIntValue

(

)

const

Get the constant integer value used by this variable to represent the comparison category result type.

Attempt to determine the integer value used to represent the comparison category result by evaluating the initializer for the specified VarDecl as a constant expression and retrieving the value of the class's first (and only) field.

Note: The STL types are expected to have the form: struct X { T value; }; where T is an integral or enumeration type.

hasValidIntValue()

bool ComparisonCategoryInfo::ValueInfo::hasValidIntValue

(

)

const

True iff we've successfully evaluated the variable as a constant expression and extracted its integer value.
