Class COM.objectspace.jgl.predicates.LessCollationKey 

java.lang.Object

   +----COM.objectspace.jgl.predicates.LessCollationKey
public final class LessCollationKey
extends Object
implements BinaryPredicate
LessCollationKey is a binary predicate that returns true if the first operand as a string is less than the second operand as a string when compared using the given Collator object. Instead of using the compare() call, getCollationKey() is used and the results of that are compared. If either operand is itself a CollationKey object, then that operand is used without getting a new key from the collator.

If an explicit Collator object is not given, the default is used.

Constructor Index

o LessCollationKey()
Construct a LessCollationKey function object that uses the collator object for the current default locale to compare objects.
o LessCollationKey(Collator)
Construct a LessCollationKey function object that uses the given collator object to compare objects.

Method Index

o execute(Object, Object)
Return true if the first operand is less than the second operand.

Constructors

o LessCollationKey 
 public LessCollationKey()
Construct a LessCollationKey function object that uses the collator object for the current default locale to compare objects.

o LessCollationKey 
 public LessCollationKey(Collator collator)
Construct a LessCollationKey function object that uses the given collator object to compare objects.

Parameters:
collator - The Collator object that is to be used for comparisons.

Methods

o execute 
 public boolean execute(Object first,
                        Object second)
Return true if the first operand is less than the second operand. Note: CollationKeys created by different Collators can not be compared.

Parameters:
first - The first operand.
second - The second operand.
Returns:
true if the sort key of the first operand is less than that of the second.
