Method Detail

getMarshallerFactory

public static MarshallerFactory getMarshallerFactory(String name)

Get a marshaller factory, by name. Uses the thread's current context classloader, if available, to locate the factory.

Parameters:

name - the name of the protocol to acquire

Returns:

the marshaller factory, or null if no matching factory was found

ServiceLoader

getMarshallerFactory

public static MarshallerFactory getMarshallerFactory(String name,
                                                     ClassLoader classLoader)

Get a marshaller factory, by name. Uses the given classloader to locate the factory.

Parameters:

name - the name of the protocol to acquire

classLoader - the class loader to use

Returns:

the marshaller factory, or null if no matching factory was found

ServiceLoader

nullStreamHeader

public static StreamHeader nullStreamHeader()

Get the default stream header producer, which reads and writes no header at all.

Returns:

the default stream header producer

streamHeader

public static StreamHeader streamHeader(byte[] headerBytes)

Create a stream header that uses the given bytes.

Parameters:

headerBytes - the header bytes

Returns:

the stream header object

readFully

public static void readFully(ByteInput input,
                             byte[] dest)
                      throws IOException

Read bytes from a ByteInput. Fully fills in the array.

Parameters:

input - the input

dest - the destination

Throws:

EOFException - if the end of file is reached before the array is filled

IOException - if an I/O error occurs

readFully

public static void readFully(ByteInput input,
                             byte[] dest,
                             int offs,
                             int len)
                      throws IOException

Read bytes from a ByteInput. Fully fills in len bytes in the array.

Parameters:

input - the input

dest - the destination

offs - the offset into the array

len - the number of bytes

Throws:

EOFException - if the end of file is reached before the array is filled

IOException - if an I/O error occurs

createByteInput

public static ByteInput createByteInput(ByteBuffer buffer)

Create a ByteInput wrapper for a ByteBuffer.

Parameters:

buffer - the byte buffer

Returns:

the byte input wrapper

createByteInput

public static ByteInput createByteInput(InputStream inputStream)

Create a ByteInput wrapper for an InputStream.

Parameters:

inputStream - the input stream

Returns:

the byte input wrapper

createInputStream

public static InputStream createInputStream(ByteInput byteInput)

Create an InputStream wrapper for a ByteInput.

Parameters:

byteInput - the byte input

Returns:

the input stream wrapper

createByteOutput

public static ByteOutput createByteOutput(ByteBuffer buffer)

Create a ByteOutput wrapper for a ByteBuffer.

Parameters:

buffer - the byte buffer

Returns:

the byte output wrapper

createByteOutput

public static ByteOutput createByteOutput(OutputStream outputStream)

Create a ByteOutput wrapper for an OutputStream.

Parameters:

outputStream - the output stream

Returns:

the byte output wrapper

createOutputStream

public static OutputStream createOutputStream(ByteOutput byteOutput)

Create a OutputStream wrapper for a ByteOutput.

Parameters:

byteOutput - the byte output

Returns:

the output stream wrapper

nullClassExternalizerFactory

public static ClassExternalizerFactory nullClassExternalizerFactory()

Return the null class externalizer factory. This instance does not externalize any classes.

Returns:

the null class externalizer factory

nullObjectResolver

public static ObjectResolver nullObjectResolver()

Return the null object resolver. This instance does not translate objects in any way.

Returns:

the null object resolver

nullObjectTable

public static ObjectTable nullObjectTable()

Return the null object instance table. This instance contains no predefined instances.

Returns:

the null instance table

nullClassTable

public static ClassTable nullClassTable()

Return the null class table instance. This instance contains no predefined classes.

Returns:

the null class table

createOptionalDataException

public static OptionalDataException createOptionalDataException(boolean eof)

Construct a new OptionalDataException. This method is necssary because there are no public constructors in the API.

Returns:

a new OptionalDataException

createOptionalDataException

public static OptionalDataException createOptionalDataException(int length)

Construct a new OptionalDataException. This method is necssary because there are no public constructors in the API.

Parameters:

length - the number of bytes of primitive data available to be read in the current buffer

Returns:

a new OptionalDataException

nullExternalizer

public static Externalizer nullExternalizer()

Get a null externalizer. Useful in conjunction with ObjectTable entries. This externalizer reads and writes no data.
