StringCollator |
getCollator()
Get the collation used by this AtomicComparer if any
|
static ComparableAtomicValueComparer |
getInstance()
Get the singleton instance of this class
|
AtomicComparer |
provideContext(XPathContext context)
Supply the dynamic context in case this is needed for the comparison
|
java.lang.String |
save()
Create a string representation of this AtomicComparer that can be saved in a compiled
package and used to reconstitute the AtomicComparer when the package is reloaded
