Class MethodSignature

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

Deprecated. In 5.3, to be removed in a later release

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.

This version of MethodSignature works with loaded classes, and it usually used in the context of ClassFab to create new classes and subclasses.

Method Summary

boolean	equals(Object o) Deprecated. Returns true if the other object is an instance of MethodSignature with identical values for return type, name, parameter types and exception types.
Class[]	getExceptionTypes() Deprecated. Returns the exceptions for this method.
Method	getMethod() Deprecated. If this signature was created from a method, return that method.
String	getName() Deprecated.
Class[]	getParameterTypes() Deprecated. Returns the parameter types for this method.
Class	getReturnType() Deprecated.
String	getUniqueId() Deprecated. Returns a string consisting of the name of the method and its parameter types.
int	hashCode() Deprecated.
boolean	isOverridingSignatureOf(MethodSignature ms) Deprecated. 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).
String	toString() Deprecated.

MethodSignature

public MethodSignature(Class returnType,
                       String name,
                       Class[] parameterTypes,
                       Class[] exceptionTypes)

Deprecated.

MethodSignature

public MethodSignature(Method m)

Deprecated.

Method Detail

getExceptionTypes

public Class[] getExceptionTypes()

Deprecated.

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

getName

public String getName()

Deprecated.

getMethod

public Method getMethod()

Deprecated.

If this signature was created from a method, return that method.

Since:

5.3

getParameterTypes

public Class[] getParameterTypes()

Deprecated.

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

getReturnType

public Class getReturnType()

Deprecated.

hashCode

public int hashCode()

Deprecated.

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Deprecated.

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:

isOverridingSignatureOf(MethodSignature)

toString

public String toString()

Deprecated.

Overrides:

toString in class Object

getUniqueId

public String getUniqueId()

Deprecated.

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(MethodSignature)

isOverridingSignatureOf

public boolean isOverridingSignatureOf(MethodSignature ms)

Deprecated.

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).
