 +===== Introduction =====
 +
 +This RFC proposes improvements to the way we handle type information in reflection. This work will make it easier for writing tools that convert type information from reflection into strings. This RFC also adds support the reflection API for type information return types if the [[returntypehinting|Return Type RFC]] is accepted.
  
 ===== Proposal ===== ===== Proposal =====
  
-Add ReflectionParameter::hasTypehint() and ReflectionParameter::getTypehintText() to make parsing function/method signatures and replicating them for mocking frameworks simpler.+This RFC proposes a new class ''ReflectionTypeAnnotation'' to represent type information. This RFC adds methods to ''ReflectionParameter'' to use this new class: <php>ReflectionParameter::hasTypeAnnotation()</php> and <php>ReflectionParameter::getTypeAnnotation()</php>. If the Return Type RFC is accepted it will then it will also use this new ''ReflectionTypeAnnotation'' class.
  
-Current mocking frameworks have to cast the ReflectionParameter to a string, then text parse that string to retrieve the information.+The class ''ReflectionTypeAnnotation'' also has ''%%__toString%%'' method to make parsing function/method signatures and replicating them for mocking frameworks simpler; current mocking frameworks have to cast the ReflectionParameter to a string, then text parse that string to retrieve the information.

-While getTexthint() might seem the obvious choiceI wanted to leave that open for compatibility in case we ever decide to return a "ReflectionTypehinttype object getTypehintText() indicates that we're specifically asking for the string version of the typehint.+<PHP> 
 +class ReflectionTypeAnnotation implements Reflector { 
 +    public function __toString() { /* returns type annotation string (e.g. "array", "stdClass", etc...) */ } 
 +    public function isArray() { /* true if the typehint is "array" */ } 
 +    public function isCallable() { /* true if the typehint is "callable" */ } 
 +    public function isNullable() { /* true if NULL is an acceptable value */ }
