public final class JoinpointClassification
extends Object

This class represents the classification of a joinpoint. JoinpointClassification is an implementation of the Enum Type Pattern, described by Joshua Block on his book entitled "Effective Java Programming Language Guide".

Field Summary

static JoinpointClassification	DYNAMICALY_WRAPPED Indicates that the joinpoint must be wrapped inside a code block for interception due only to dynamic bindings.
static JoinpointClassification	NOT_INSTRUMENTED Indicates that the joinpoint mustn't be instrumented.
static JoinpointClassification	PREPARED Indicates that the joinpoint must be prepared for runtime wrapping.
static JoinpointClassification	WRAPPED Indicates that the joinpoint must be wrapped inside a code block for interception.

Method Summary

boolean	equals(Object other)
String	toString() Returns a description of the joinpoint classification.

Field Detail

NOT_INSTRUMENTED

public static JoinpointClassification NOT_INSTRUMENTED

Indicates that the joinpoint mustn't be instrumented.

PREPARED

public static JoinpointClassification PREPARED

Indicates that the joinpoint must be prepared for runtime wrapping.

WRAPPED

public static JoinpointClassification WRAPPED

Indicates that the joinpoint must be wrapped inside a code block for interception.

DYNAMICALY_WRAPPED

public static JoinpointClassification DYNAMICALY_WRAPPED

Indicates that the joinpoint must be wrapped inside a code block for interception due only to dynamic bindings. This status is necessary to diferentatiate from WRAPPED. When a joinpoint will be wrapped due to a dynamic aop operation, considering the class containing the joinpoint is being loaded after the dynamic operation was performed, and the joinpoint is, for example, a field read, we know we will have to replace fiel reads in classes already loaded by the field read wrapper. So, this status is a flag telling: "you may have to replace the joinpoint executions by the joinpoint wrappers in already loaded classes (only in hot swap enabled case).
