Class Filter

java.lang.Object

com.exsoinn.util.epf.Filter

All Implemented Interfaces:

Map<String,String>

public final class Filter
extends Object
implements Map<String,String>

Unmodifiable class to encapsulate a Filter used when searching an element off of a Context object. The sole factory method used to build a Filter instance accepts a filter String that follows the following format only: key1=val1;key2=val2;key3=val3 If the filter String can't be successfully parsed for whatever reason, IllegalArgumentException gets thrown. This class is a specialized implementation of Map interface, backed by a Map instance to which all Map operations are forwarded (composition design pattern). It will throw UnsupportedOperationException on any method invocation of Map that would otherwise modify the underlying Map, because instances of this class aremeant to be read-ony.
