Class PointcutParser

java.lang.Object
  org.aspectj.weaver.tools.PointcutParser

public class PointcutParser

extends Object

A PointcutParser can be used to build PointcutExpressions for a user-defined subset of AspectJ's pointcut language

Constructor Summary

PointcutParser()
Create a pointcut parser that can parse the full AspectJ pointcut language with the following exceptions: The if, cflow, and cflowbelow pointcut designators are not supported Pointcut expressions must be self-contained :- they cannot contain references to other named pointcuts The pointcut expression must be anonymous with no formals allowed.

PointcutParser(Set supportedPointcutKinds)
Create a pointcut parser that can parse pointcut expressions built from a user-defined subset of AspectJ's supported pointcut primitives.

Method Summary

static Set	getAllSupportedPointcutPrimitives()
PointcutExpression	parsePointcutExpression(String expression) Parse the given pointcut expression.

Constructor Detail

PointcutParser

public PointcutParser()

Create a pointcut parser that can parse the full AspectJ pointcut language with the following exceptions:

• The if, cflow, and cflowbelow pointcut designators are not supported
• Pointcut expressions must be self-contained :- they cannot contain references to other named pointcuts
• The pointcut expression must be anonymous with no formals allowed.

PointcutParser

public PointcutParser(Set supportedPointcutKinds)

Create a pointcut parser that can parse pointcut expressions built from a user-defined subset of AspectJ's supported pointcut primitives. The following restrictions apply:

• The if, cflow, and cflowbelow pointcut designators are not supported
• Pointcut expressions must be self-contained :- they cannot contain references to other named pointcuts
• The pointcut expression must be anonymous with no formals allowed.

Parameters:

supportedPointcutKinds - a set of PointcutPrimitives this parser should support

Throws:

UnsupportedOperationException - if the set contains if, cflow, or cflow below

Method Detail

getAllSupportedPointcutPrimitives

public static Set getAllSupportedPointcutPrimitives()

Returns:

a Set containing every PointcutPrimitive except if, cflow, and cflowbelow (useful for passing to PointcutParser constructor).

parsePointcutExpression

public PointcutExpression parsePointcutExpression(String expression)
                                           throws UnsupportedOperationException,
                                                  IllegalArgumentException

Parse the given pointcut expression.

Throws:

UnsupportedOperationException - if the parser encounters a primitive pointcut expression of a kind not supported by this PointcutParser.

IllegalArgumentException - if the expression is not a well-formed pointcut expression
