Class IvyEventFilter

java.lang.Object
  extended by org.apache.ivy.core.event.IvyEventFilter
All Implemented Interfaces:
Filter

public class IvyEventFilter
extends java.lang.Object
implements Filter

A filter implementation filtering IvyEvent based upon an event name and a filter expression. The name will be matched against the event name using the PatternMatcher used to construct this object. The filter expression is a string describing how the event should be filtered according to its attributes values. The matching between the filter values and the event attribute values is done using the PatternMatcher used to construct this object. Here are some examples:

expression effect
type=zip accepts event with a type attribute matching zip
type=zip,jar accepts event with a type attribute matching zip or jar
type=src AND ext=zip accepts event with a type attribute matching src AND an ext attribute matching zip
type=src OR ext=zip accepts event with a type attribute matching src OR an ext attribute matching zip
NOT type=src accepts event with a type attribute NOT matching src
Combination of these can be used, but no parentheses are supported right now, so only the default priority can be used. The priority order is this one: AND OR NOT = This means that artifact=foo AND ext=zip OR type=src will match event with artifact matching foo AND (ext matching zip OR type matching src)
