Imports

A privileged access munger is for handling privileged access to a member. It determines the names of the getter/setter that will be used to access a private field in some type, or the special method that provides access to a private method. There are two syntax styles for field access, the older style was in use up to AspectJ 1.6.9 and involves long named getters and setters which include the requesting aspect and the target type. The short style syntax is use from AspectJ 1.6.9 onwards is simply 'ajc$get$<fieldname>' and 'ajc$set$<fieldname>' - as the requesting aspect isn't included in the name they can be shared across aspects.

public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

public boolean existsToSupportShadowMunging()

Overrides org.aspectj.weaver.ResolvedTypeMunger.existsToSupportShadowMunging.

Doc from org.aspectj.weaver.ResolvedTypeMunger.existsToSupportShadowMunging.

Some type mungers are created purely to help with the implementation of shadow mungers. For example to support the cflow() pointcut we create a new cflow field in the aspect, and that is added via a BcelCflowCounterFieldAdder. During compilation we need to compare sets of type mungers, and if some only come into existence after the 'shadowy' type things have been processed, we need to ignore them during the comparison. Returning true from this method indicates the type munger exists to support 'shadowy' stuff - and so can be ignored in some comparison.

public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the 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.
