Constructor Detail

TypePatternClassFilter

public TypePatternClassFilter()
Creates a new instance of the TypePatternClassFilter class.

public TypePatternClassFilter(String typePattern)
Create a fully configured TypePatternClassFilter using the given type pattern.

Parameters:
typePattern - the type pattern that AspectJ weaver should parse

Method Detail

setTypePattern

public void setTypePattern(String typePattern)

These conventions are established by AspectJ, not Spring AOP.

Parameters:
