inline

public Expression inline(ApplyExp exp,
                         InlineCalls walker,
                         boolean argsInlined)

Description copied from interface: CanInline

Inline an application of this Procedure and return result. Unless argsInlined is true, then this method is responsible for walking exp.getArgs(); you can handle this using exp.getArgs(walker, argsInlined). (The exp.getFunction() has been walked, regardless.)

Specified by:

inline in interface CanInline

argsInlined - true if the arguments have been inlined. Can return original expression.
