parseHasMethodTypePattern

public TypePattern parseHasMethodTypePattern()

parseIsTypePattern

public TypePattern parseIsTypePattern()

Attempt to parse a typeIs(<category>) construct. If it cannot be parsed we just return null and that should cause the caller to reset their position and attempt to consume it in another way. This means we won't have problems here: execution(* typeIs(..)) because someone has decided to call a method the same as our construct.

Returns:

a TypeIsTypePattern or null if could not be parsed
