getDocument

public OMDocument getDocument()

Description copied from interface: OMXMLParserWrapper

Get the document being built by this builder.

Specified by:

getDocument in interface OMXMLParserWrapper

Returns:

the OMDocument instance

getRootElement

public OMElement getRootElement()

Get the root element of the Axiom tree built by this content handler.

Returns:

the root element of the tree

Throws:

OMException - if the tree is not complete

next

public int next()
         throws OMException

Description copied from interface: OMXMLParserWrapper

Proceed the parser one step and return the event value.

Specified by:

next in interface OMXMLParserWrapper

Returns:

Returns int.

Throws:

OMException

discard

public void discard(OMElement el)
             throws OMException

Specified by:

discard in interface OMXMLParserWrapper

Throws:

OMException

setCache

public void setCache(boolean b)
              throws OMException

Specified by:

setCache in interface OMXMLParserWrapper

Throws:

OMException

isCache

public boolean isCache()

Specified by:

isCache in interface OMXMLParserWrapper

Returns:

true if caching

getParser

public Object getParser()

Description copied from interface: OMXMLParserWrapper

Allows to access the underlying parser. Since the parser depends on the underlying implementation, an Object is returned. However the implementations may have restrictions in letting access to the parser.

Specified by:

getParser in interface OMXMLParserWrapper

Returns:

Returns Object.

isCompleted

public boolean isCompleted()

Specified by:

isCompleted in interface OMXMLParserWrapper

Returns:

Returns the complete status.

getDocumentElement

public OMElement getDocumentElement()

Description copied from interface: OMXMLParserWrapper

Get the document element, i.e. the root element of the document. Using this method is equivalent to using OMDocument.getOMDocumentElement() on the document returned by OMXMLParserWrapper.getDocument().

Note that this method will never return null (except in the very special case where the document has been requested before and the document element has been removed explicitly): if the document being parsed has no document element, then this will result in a parser error, i.e. an OMException will be thrown.

Specified by:

getDocumentElement in interface OMXMLParserWrapper

Returns:

the document element

getDocumentElement

public OMElement getDocumentElement(boolean discardDocument)

Description copied from interface: OMXMLParserWrapper

Get the document element, optionally discarding the document. The return value of this method is the same as OMXMLParserWrapper.getDocumentElement(). However, if the discardDocument parameter is set to true, then the document element is removed from the document and the document itself is discarded. In contrast to using OMNode.detach() this will not build the element. The implementation also ensures that the element is not built when it is added to another OM tree. This makes it possible to add the content of a document to an existing OM tree while preserving the deferred parsing feature. It is even possible to create an OM tree where different subtrees are associated with different builder instances.

Specified by:

getDocumentElement in interface OMXMLParserWrapper

Parameters:

discardDocument - specifies whether the document should be discarded

Returns:

the document element

getBuilderType

public short getBuilderType()

Description copied from interface: OMXMLParserWrapper

Returns the type of the builder. Can be either OMConstants.PUSH_TYPE_BUILDER or OMConstants.PULL_TYPE_BUILDER.

Specified by:

getBuilderType in interface OMXMLParserWrapper

Returns:

Returns short.

registerExternalContentHandler

public void registerExternalContentHandler(Object obj)

Description copied from interface: OMXMLParserWrapper

Registers an external content handler. Especially useful for push type builders. Throws an unsupportedOperationException if such handler registration is not supported.

Specified by:

registerExternalContentHandler in interface OMXMLParserWrapper

getRegisteredContentHandler

public Object getRegisteredContentHandler()

Description copied from interface: OMXMLParserWrapper

get the registered external content handler

Specified by:

getRegisteredContentHandler in interface OMXMLParserWrapper

Returns:

Returns Object.

getCharacterEncoding

public String getCharacterEncoding()

Description copied from interface: OMXMLParserWrapper

Returns the encoding style of the XML data

Specified by:

getCharacterEncoding in interface OMXMLParserWrapper

Returns:

the character encoding, defaults to "UTF-8"

close

public void close()

Description copied from interface: OMXMLParserWrapper

Close this builder. This method frees the resources associated with this builder. In particular, it releases the resources held by the underlying parser. This method does not close the underlying input source.

Specified by:

close in interface OMXMLParserWrapper
