                         int operation)

Primary Constructor

Parameters:

key - the key for which the record's value is fetched

value - the value with which to the compare the record's value for the specified key

operation - the code corresponding to the comparison operation

KeyValueQualifier

public KeyValueQualifier(java.lang.String key,
                         java.lang.Comparable value)

Constructor in which the default comparison operation (equality) is used.

Parameters:

key - the key for which the record's value is fetched

value - the value with which to the compare the record's value for the specified key

Method Detail

matches

public boolean matches(java.lang.Object object)

Determine if the specified object is a match to this qualifier's criteria. The object must implement the KeyedRecord interface and its value corresponding to _key must implement the java.util.Comparable interface. See java.util.Comparable for more information.

Specified by:

matches in interface Qualifier

Parameters:

object - the object to test for matching

Returns:

true if the object matches the criteria and false if not.

Throws:

java.lang.ClassCastException - if the object does not implement the Comparable interface

toString

public java.lang.String toString()

Get a string representation of this instance

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this instance.
