Method Summary

java.util.Map	getCflowExpressions() Return a Map(name->Expression) of expression involved in the IN and NOT IN sub-expression of this Expression (can be empty)
boolean	isHierarchical() Checks if the expression is hierachical.
boolean	isHierarchicalCallee() Checks if the expression is hierachical on Callee side.

Method Detail

isHierarchical

public boolean isHierarchical()

Checks if the expression is hierachical.

Returns:

boolean

isHierarchicalCallee

public boolean isHierarchicalCallee()

Checks if the expression is hierachical on Callee side.

Returns:

boolean

match

public boolean match(ClassMetaData classMetaData)

Match class pattern only

Specified by:

match in class Expression

Parameters:

classMetaData - the class meta-data

Returns:

boolean

matchInOrNotIn

public boolean matchInOrNotIn(ClassMetaData classMetaData)

Match one part appearing in IN / NOT IN sub-expression Makes sense only with CallExpression

Specified by:

matchInOrNotIn in class Expression

Parameters:

classMetaData -

Returns:

true if match

matchInOrNotIn

public boolean matchInOrNotIn(ClassMetaData classMetaData,
                              MemberMetaData memberMetaData)

Match one part appearing in IN / NOT IN sub-expression Makes sense only with CallExpression

Specified by:

matchInOrNotIn in class Expression

Parameters:

classMetaData -

memberMetaData - the meta-data for the member

Returns:

true if match

match

public boolean match(ClassMetaData classMetaData,
                     MemberMetaData memberMetaData,
                     java.lang.String exceptionType)

Checks if the expression matches a certain join point.

Special case in the API which tries to match exception types as well. Overrided by ThrowsExpression

Specified by:

match in class Expression

Parameters:

classMetaData - the class meta-data

memberMetaData - the meta-data for the member

exceptionType - the exception type (null => match all)

Returns:

boolean

Description copied from class: Expression

Return a Map(name->Expression) of expression involved in the IN and NOT IN sub-expression of this Expression (can be empty)

Specified by:

getCflowExpressions in class Expression

Returns:

Map(name->Expression)
