int SeExpr2::ExprCondNode::buildInterpreter ( Interpreter * interpreter ) const

virtual

builds an interpreter. Returns the location index for the evaluated data

Reimplemented from SeExpr2::ExprNode.

Definition at line 884 of file Interpreter.cpp.

virtual LLVM_VALUE SeExpr2::ExprCondNode::codegen ( LLVM_BUILDER )

virtual

Reimplemented from SeExpr2::ExprNode.

ExprType SeExpr2::ExprCondNode::prep	(	bool	dontNeedScalar,
		ExprVarEnvBuilder &	envBuilder
	)

virtual

Prepare the node (for parser use only). See the discussion at the start of SeExprNode.cpp for more info.

Default is to call prep on children (giving AnyType as desired type). If all children return valid types, returns NoneType. Otherwise, returns ErrorType. Note: Ignores wanted type.

Reimplemented from SeExpr2::ExprNode.
