Class WstxInputFactory

java.lang.Object

javax.xml.stream.XMLInputFactory

org.codehaus.stax2.XMLInputFactory2

com.ctc.wstx.stax.WstxInputFactory

All Implemented Interfaces:

InputConfigFlags, ReaderCreator, org.codehaus.stax2.XMLStreamProperties

public class WstxInputFactory
extends org.codehaus.stax2.XMLInputFactory2
implements ReaderCreator, InputConfigFlags

Factory for creating various Stax objects (stream/event reader, writer).

Currently supported configuration options fall into two categories. First, all properties from XMLInputFactory (such as, say, XMLInputFactory.IS_NAMESPACE_AWARE) are at least recognized, and most are supported. Second, there are additional properties, defined in constant class WstxInputProperties, that are supported. See WstxInputProperties for further explanation of these 'custom' properties.

Method that is eventually called to create a (full) stream read instance.

Note: defined as public method because it needs to be called by SAX implementation.

Parameters:

systemId - System id used for this reader (if any)

bs - Bootstrapper to use for creating actual underlying physical reader

forER - Flag to indicate whether it will be used via Event API (will affect some configuration settings), true if it will be, false if not (or not known)

autoCloseInput - Whether the underlying input source should be actually closed when encountering EOF, or when close() is called. Will be true for input sources that are automatically managed by stream reader (input streams created for URL and File arguments, or when configuration settings indicate auto-closing is to be enabled (the default value is false as per Stax 1.0 specs).

Throws:

XMLStreamException

Another internal factory method, used when dealing with a generic Source base type. One thing worth noting is that 'auto-closing' will be enabled if the input source or Reader is constructed (and thus owned) by Woodstox.

Parameters:

forER - True, if the reader is being constructed to be used by an event reader; false if it is not (or the purpose is not known)

Throws:

XMLStreamException

createEventAllocator

protected XMLEventAllocator createEventAllocator()

createPrivateConfig

public ReaderConfig createPrivateConfig()

Method called to construct a copy of the factory's configuration object, such that two will be unlinked (changes to one are not reflect in the other).

Note: only public so that other woodstox components outside of this package can access it.
