FunctionType * FunctionType::get	(	const Type *	Result,
		const std::vector< const Type * > &	Params,
		bool	isVarArg
	)			[static]

FunctionType::get - This static method is the primary way of constructing a FunctionType.

Parameters:

Result	The result type
Params	The types of the parameters
isVarArg	Whether this is a variable argument length function

void FunctionType::refineAbstractType	(	const DerivedType *	OldTy,
		const Type *	NewTy
	)			[virtual]

refineAbstractType - The callback method invoked when an abstract type is resolved to another type. An object must override this method to update its internal state to reference NewType instead of OldType.

Reimplemented from llvm::Type.

Definition at line 1455 of file Type.cpp.

void FunctionType::typeBecameConcrete

(

const DerivedType *

AbsTy

)

[virtual]

The other case which AbstractTypeUsers must be aware of is when a type makes the transition from being abstract (where it has clients on it's AbstractTypeUsers list) to concrete (where it does not). This method notifies ATU's when this occurs for a type.
