JavaBeansXmlAdapter()

Method Summary

void	exceptionThrown(java.lang.Exception e)
java.lang.String	getContentType()
boolean	isSelfBuffered() Indicates that the adapter uses a StreamBuffer mechanism and doesn't require a buffered input stream
java.lang.Object	read(java.io.InputStream in) Deserializes an object out of an given InputStream
boolean	requiresCustomEOFHandling() Signals if this adapter has problems with EJOE's UncloseableInputStreams and requires a really closed Stream (which EJOE prevents to ensure that an adapter can not close the underlying socket unintentionally).
void	write(java.lang.Object obj, java.io.OutputStream out) Serializes an object into an output stream

JavaBeansXmlAdapter

public JavaBeansXmlAdapter()

Method Detail

read

public java.lang.Object read(java.io.InputStream in)
                      throws java.lang.Exception

Description copied from interface: SerializeAdapter

Deserializes an object out of an given InputStream

Specified by:

read in interface SerializeAdapter

Parameters:

in - the input stream to use for deserialization

Returns:

a deserialized object instance

Throws:

java.lang.Exception

write

public void write(java.lang.Object obj,
                  java.io.OutputStream out)
           throws java.lang.Exception

Description copied from interface: SerializeAdapter

Serializes an object into an output stream

Specified by:

write in interface SerializeAdapter

Parameters:

obj - object that should get serialized

out - the outputstream into which the object should serialized

Throws:

java.lang.Exception

exceptionThrown

public void exceptionThrown(java.lang.Exception e)

Specified by:

exceptionThrown in interface java.beans.ExceptionListener

requiresCustomEOFHandling

public boolean requiresCustomEOFHandling()

Description copied from interface: SerializeAdapter

Signals if this adapter has problems with EJOE's UncloseableInputStreams and requires a really closed Stream (which EJOE prevents to ensure that an adapter can not close the underlying socket unintentionally). If the adapter requires closed streams, EJOE will append a custom EOF signature at the end of the stream and return -1 in Inputstream#read when EOF is reached.

Specified by:

requiresCustomEOFHandling in interface SerializeAdapter

Overrides:

requiresCustomEOFHandling in class BaseAdapter

Returns:

true if the adapter requires EOF to detect the end of the stream

isSelfBuffered

public boolean isSelfBuffered()

Description copied from interface: SerializeAdapter

Indicates that the adapter uses a StreamBuffer mechanism and doesn't require a buffered input stream

Specified by:

isSelfBuffered in interface SerializeAdapter

Overrides:

isSelfBuffered in class BaseAdapter

Returns:

true if the adapter doesn't require a buffered inputstream, otherwise false

getContentType

public java.lang.String getContentType()

Specified by:

getContentType in interface SerializeAdapter

Overrides:

getContentType in class BaseAdapter

Returns:

A recognized mime type
