Class MethodSignature

java.lang.Object
org.apache.tapestry5.ioc.internal.services.MethodSignature

public class MethodSignature extends Object
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 Details

    • getExceptionTypes

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

      public String getName()
    • getMethod

      public Method getMethod()
      If this signature was created from a method, return that method.

      5.3
    • getParameterTypes

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

      public Class getReturnType()
    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object
    • equals

      public boolean equals(Object o)
      Returns true if the other object is an instance of MethodSignature with identical values for return type, name, parameter types and exception types.
      Overrides:
      equals in class Object
      See Also:
    • toString

      public String toString()
      Overrides:
      toString in class Object
    • getUniqueId

      public String getUniqueId()
      Returns a string consisting of the name of the method and its parameter types. This is similar to toString(), but omits the return type and information about thrown exceptions. A unique id is used by MethodIterator 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).
