Package com.fasterxml.jackson.databind.ext

Class OptionalHandlerFactory

java.lang.Object

com.fasterxml.jackson.databind.ext.OptionalHandlerFactory

All Implemented Interfaces:

java.io.Serializable

public class OptionalHandlerFactory
extends java.lang.Object
implements java.io.Serializable

Helper class used for isolating details of handling optional+external types (javax.xml classes) from standard factories that offer them.

Note that 2.7 changed handling to slightly less dynamic, to avoid having to traverse class hierarchy, which turned to be a performance issue in certain cases. Since DOM classes are assumed to exist on all Java 1.6 environments (yes, even on Android/GAE), this part could be simplified by slightly less dynamic lookups.

Also with 2.7 we are supporting JDK 1.7/Java 7 type(s).

Since 2.7 we only need to check for class extension, as all implemented types are classes, not interfaces. This has performance implications for some cases, as we do not need to go over interfaces implemented, just superclasses

Since:
