Class Stax2ReferentialSource

java.lang.Object

org.codehaus.stax2.io.Stax2Source

org.codehaus.stax2.io.Stax2ReferentialSource

All Implemented Interfaces:

javax.xml.transform.Source

Direct Known Subclasses:

Stax2FileSource, Stax2URLSource

public abstract class Stax2ReferentialSource
extends Stax2Source

This is the mid-level abstract base class for Stax2Sources that refer to a resource in such a way, that an efficient InputStream or Reader can be constructed. Additionally, referenced sources also provide the base URI that allows for resolving relative references from within content read from such resources. Typical examples of references are URL and File: both for which a default implementations exist in this package

Stax2FileSource, Stax2URLSource

Method Detail

getReference

public abstract java.net.URL getReference()

Specified by:

getReference in class Stax2Source

Returns:

URL that can be used to resolve references originating from the content read via this source; may be null if not known (which is the case for most non-referential sources)

constructReader

public abstract java.io.Reader constructReader()
                                        throws java.io.IOException

Description copied from class: Stax2Source

This method creates a Reader via which underlying input source can be accessed. Note that caller is responsible for closing that Reader when it is done reading it.

Specified by:

constructReader in class Stax2Source

Throws:

java.io.IOException

constructInputStream

public abstract java.io.InputStream constructInputStream()
                                                  throws java.io.IOException

Description copied from class: Stax2Source

This method creates an InputStream via which underlying input source can be accessed. Note that caller is responsible for closing that InputSource when it is done reading it

Specified by:

constructInputStream in class Stax2Source

Throws:

java.io.IOException

getSystemId

public java.lang.String getSystemId()

Since we can determine a system id from the base URL

Specified by:

getSystemId in interface javax.xml.transform.Source

Overrides:

getSystemId in class Stax2Source
