Implements org.springframework.cglib.proxy.CallbackFilter.accept.

Map a method to a callback.

public boolean
equals(Object
the reference object with which to compare.

Overrides java.lang.Object.equals.

Implements org.springframework.cglib.proxy.CallbackFilter.equals.

The CallbackFilter in use affects which cached class the Enhancer will use, so this is a reminder that you should correctly implement equals and hashCode for custom CallbackFilter implementations in order to improve performance.

public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object
