Member Function Documentation

list<Type *> TypeHelper::get_arguments (CProcedureType * proc) [static]

Get the list of arguments for the procedure type proc.

Returns:

a list of Type*. If proc has no prototype, returns an empty list.

bool TypeHelper::is_unknown_bound (ArrayType * arr) [static]

Returns:

true iff the array type arr has unknown lower and upper bound.

bool TypeHelper::is_unknown_but_compatible_bound (ArrayType * a1, ArrayType * a2) [static]

Returns:

true iff a1 has unknown bounds but still compatible with a2

bool TypeHelper::is_unknown_int (Expression * exp) [static]

Returns:

true if exp describes an undetermined integer.

bool TypeHelper::is_same_qualified (QualifiedType * qt1, QualifiedType * qt2) [static]

Returns:

true iff qt1 and qt2 have the same set of qualifications.

bool TypeHelper::is_isomorphic_type (Type * t1, Type * t2, TypePairStack * st = NULL) [static]

Returns:

true iff t1 and t2 are isomorphic structurally.

bool TypeHelper::is_isomorphic_bound (ArrayType * a1, ArrayType * a2) [static]

Returns:

true if the upper- and lower-bounds of a1 and a2 are isomorphic.

bool TypeHelper::is_isomorphic_int (Expression * e1, Expression * e2) [static]

Returns:

true if e1 and e2 describes the same integer constant.

Type * TypeHelper::find_isomorphic_type (Type * oldtype, SymbolTable * symtab) [static]

Returns:

a Type* from symtab that is isomorphic with t1. Return NULL if symtab contains no such type object.

FieldSymbol * TypeHelper::lookup_field (const GroupSymbolTable * gatb, const String & fieldname) [static]

Returns:

the FieldSymbol from gtab with name fieldname. return NULL if not found.
