Class MethodSignature
java.lang.Object
org.apache.tapestry5.ioc.internal.services.MethodSignature
A representation of a
Method
, identifying the name, return type, parameter types and
exception types. Actual Method objects are tied to a particular class, and don't compare well with other otherwise
identical Methods from other classes or interface; MethodSignatures are distinct from classes and compare well.
Because the intended purpose is to compare methods from interfaces (which are always public and abstract) we don't
bother to actually track the modifiers. In addition, at this time, MethodSignature does not distinguish between
instance and static methods.-

Method Summary
Modifier and TypeMethodDescriptionboolean
Returns true if the other object is an instance of MethodSignature with identical values for return type, name, parameter types and exception types.Class[]
Returns the exceptions for this method.If this signature was created from a method, return that method.getName()
Class[]
Returns the parameter types for this method.Returns a string consisting of the name of the method and its parameter types.int
hashCode()
boolean
Returns true if this signature has the same return type, name and parameters types as the method signature passed in, and this signature's exceptions "trump" (are the same as, or super-implementations of, all exceptions thrown by the other method signature).toString()

getExceptionTypes
Returns the exceptions for this method. Caution: do not modify the returned array. May return null. -

getMethod
If this signature was created from a method, return that method.- Since:

-
getParameterTypes
Returns the parameter types for this method. May return null. Caution: do not modify the returned array. -
getReturnType

hashCode

equals
Returns true if the other object is an instance of MethodSignature with identical values for return type, name, parameter types and exception types. -
toString
-
getUniqueId
Returns a string consisting of the name of the method and its parameter types. This is similar totoString()
, but omits the return type and information about thrown exceptions. A unique id is used byMethodIterator
to identify overlapping methods (methods with the same name and parameter types but with different thrown exceptions).- See Also:

isOverridingSignatureOf
Returns true if this signature has the same return type, name and parameters types as the method signature passed in, and this signature's exceptions "trump" (are the same as, or super-implementations of, all exceptions thrown by the other method signature).
