Pointcut

public class MethodPointcut

extends AbstractPointcut

Implements the pointcut concept for method access. Is an abstraction of a well defined point of execution in the program.
Could matches one or many points as long as they are well defined.
Stores the advices for the specific pointcut.

Constructor Detail

MethodPointcut

public MethodPointcut(java.lang.String expression)

Creates a new method pointcut.

Parameters:

expression - the expression for the pointcut

MethodPointcut

public MethodPointcut(java.lang.String uuid,
                      java.lang.String expression)

Creates a new method pointcut.

Parameters:

uuid - the UUID for the AspectWerkz system

expression - the expression of the pointcut

Method Detail

isNonReentrant

public boolean isNonReentrant()

Checks if the pointcut is non-reentrant.

Returns:

the non-reentrancy flag

addPointcutDef

public void addPointcutDef(PointcutDefinition pointcut)

Adds a new pointcut pattern.

Parameters:

pointcut - the pointcut definition

matches

public boolean matches(ClassMetaData classMetaData,
                       MethodMetaData methodMetaData)

Checks if the pointcut matches a certain join point.

Parameters:

methodMetaData - the meta-data for the method

Returns:

boolean

matchMethodPointcutSuperClasses

public static boolean matchMethodPointcutSuperClasses(java.lang.String name,
                                                      ClassMetaData classMetaData,
                                                      PointcutPatternTuple pointcutPattern)

Tries to finds a match at some superclass in the hierarchy. Only checks for a class match to allow early filtering. Recursive.

Parameters:

name - the name of the pointcut to evaluate

classMetaData - the class meta-data

pointcutPattern - the pointcut pattern

Returns:

boolean

matchMethodPointcutSuperClasses

public static boolean matchMethodPointcutSuperClasses(org.apache.commons.jexl.JexlContext jexlContext,

methodMetaData - the method meta-data

pointcutPattern - the pointcut pattern

Returns:

boolean
