Class CharArrayDataSource

java.lang.Object

org.apache.axiom.om.ds.OMDataSourceExtBase

org.apache.axiom.om.ds.CharArrayDataSource

All Implemented Interfaces:

OMDataSource, OMDataSourceExt

public class CharArrayDataSource
extends OMDataSourceExtBase

CharArrayDataSource is an example implementation of OMDataSourceExt. Use it to insert a char[] into an OM Tree. This data source is useful for placing characters into an OM tree, instead of having a deeply nested tree.

Method Detail

serialize

public void serialize(Writer writer,
                      OMOutputFormat format)
               throws XMLStreamException

Description copied from interface: OMDataSourceExt

Serializes element data directly to writer. Assumes that the backing object is destroyed during serialization isDestructiveWrite

Specified by:

serialize in interface OMDataSource

Specified by:

serialize in interface OMDataSourceExt

Overrides:

serialize in class OMDataSourceExtBase

Parameters:

writer - destination writer for element XML text

format - output format information (null if none; may be ignored if not supported by data binding even if supplied)

Throws:

XMLStreamException

See Also:

OMDataSourceExt

getReader

public XMLStreamReader getReader()
                          throws XMLStreamException

Description copied from interface: OMDataSourceExt

Get parser for element data. In the general case this may require the data source to serialize data as XML text and then parse that text.

Returns:

element parser

Throws:

XMLStreamException

getObject

public Object getObject()

Description copied from interface: OMDataSourceExt

Returns the backing Object.

Returns:

Object

isDestructiveRead

public boolean isDestructiveRead()

Description copied from interface: OMDataSourceExt

Returns true if reading the backing object is destructive. An example of an object with a destructive read is an InputSteam. The owning OMSourcedElement uses this information to detemine if OM tree expansion is needed when reading the OMDataSourceExt.

Returns:

boolean

isDestructiveWrite

public boolean isDestructiveWrite()

Description copied from interface: OMDataSourceExt

Returns true if writing the backing object is destructive. An example of an object with a destructive write is an InputStream. The owning OMSourcedElement uses this information to detemine if OM tree expansion is needed when writing the OMDataSourceExt.

Returns:

boolean

getXMLBytes

public byte[] getXMLBytes(String encoding)
                   throws UnsupportedEncodingException

Description copied from interface: OMDataSourceExt

Returns a byte[] representing the xml data

Parameters:

encoding - String encoding of InputStream

Returns:

byte[]

Throws:

UnsupportedEncodingException

See Also:

OMDataSourceExt.getXMLInputStream(String)

close

public void close()

Description copied from interface: OMDataSourceExt

Close the DataSource and free its resources.

copy

public OMDataSourceExt copy()

Description copied from interface: OMDataSourceExt

Create a copy of the OMDataSourceExt

Returns:

OMDataSourceExt
