 org.apache.xml.dtm.ObjectFactory
| ObjectFactory | | class ObjectFactory (Code) | | This class is duplicated for each JAXP subpackage so keep it in sync.
It is package private and therefore is not exposed as part of the JAXP
API.
This code is designed to implement the JAXP 1.1 spec pluggability
feature and is designed to run on JDK version 1.1 and
later, and to compile on JDK 1.2 and onward.
The code also runs both as part of an unbundled jar file and
when bundled as part of the JDK.
This class was moved from the javax.xml.parsers.ObjectFactory
class and modified to be used as a general utility for creating objects
dynamically.

| createObject | | static Object createObject(String factoryId, String fallbackClassName) throws ConfigurationError(Code) | | Finds the implementation Class object in the specified order. The
specified order is the following:
- query the system property using
System.getProperty
- read
META-INF/services/factoryId file
- use fallback classname
instance of factory, never null
Parameters:
factoryId - Name of the factory to find, same asa property name
Parameters:
fallbackClassName - Implementation class name, if nothing elseis found. Use null to mean no fallback.
