Class BindingMethod

java.lang.Object
  org.jibx.binding.classes.BindingMethod

Direct Known Subclasses:

ExistingMethod, MethodBuilder

public abstract class BindingMethod
extends Object

Binding method information. Tracks a method used by the binding code, supplying hash code and equality checking based on the method signature and actual byte code of the method, ignoring the method name. This allows comparisons between methods generated by different bindings, and between generated and existing methods.

Constructor Detail

BindingMethod

protected BindingMethod(ClassFile cf)

Constructor.

Parameters:

cf - owning class file information

Method Detail

getClassFile

public ClassFile getClassFile()

Get class file containing method.

Returns:

class file owning this method

getName

public abstract String getName()

Get name of method. This abstract method must be implemented by every subclass.

Returns:

method name

getSignature

public abstract String getSignature()

Get signature. This abstract method must be implemented by every subclass.

Returns:

signature for method

getAccessFlags

public abstract int getAccessFlags()

Get access flags. This abstract method must be implemented by every subclass.

Returns:

flags for access type of method

setAccessFlags

public abstract void setAccessFlags(int flags)

Set access flags. This abstract method must be implemented by every subclass.

Parameters:

flags - access type to be set

getMethod

public abstract org.apache.bcel.classfile.Method getMethod()

Get the actual method.

Returns:

method information

getItem

public abstract ClassItem getItem()

Get the method item.

Returns:

method item information

makeAccessible

public void makeAccessible(ClassFile src)

Make accessible method. Check if this method is accessible from another class, and if not decreases the access restrictions to make it accessible.

Parameters:

src - class file for required access

computeMethodHash

public static int computeMethodHash(org.apache.bcel.classfile.Method method)

Computes the hash code for a method. The hash code is based on the method signature, the exceptions thrown, and the actual byte code (including the exception handlers).

Returns:

computed hash code for method

hashCode

public abstract int hashCode()

Get hash code. This abstract method must be implemented by every subclass, using the same algorithm in each case. See one of the existing subclasses for details.

Overrides:

hashCode in class Object

Returns:

hash code for this method

equals

public boolean equals(Object obj)

Check if objects are equal. Compares first based on hash code, then on the actual byte code sequence.

Overrides:

equals in class Object

Returns:

true if equal objects, false if not
