Method Detail

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 java.io.IOException

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

Parameters:

input - the input

dest - the destination

Throws:

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

java.io.IOException - if an I/O error occurs

readFully

public static void readFully(ByteInput input,
                             byte[] dest,
                             int offs,
                             int len)
                      throws java.io.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:

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

java.io.IOException - if an I/O error occurs

createByteInput

public static ByteInput createByteInput(java.nio.ByteBuffer buffer)

Create a ByteInput wrapper for a ByteBuffer.

Parameters:

buffer - the byte buffer

Returns:

the byte input wrapper

createByteInput

public static ByteInput createByteInput(java.io.InputStream inputStream)

Create a ByteInput wrapper for an InputStream.

Parameters:

inputStream - the input stream

Returns:

the byte input wrapper

createInputStream

public static java.io.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(java.nio.ByteBuffer buffer)

Create a ByteOutput wrapper for a ByteBuffer.

Parameters:

buffer - the byte buffer

Returns:

the byte output wrapper

createByteOutput

public static ByteOutput createByteOutput(java.io.OutputStream outputStream)

Create a ByteOutput wrapper for an OutputStream.

Parameters:

outputStream - the output stream

Returns:

the byte output wrapper

createOutputStream

public static java.io.OutputStream createOutputStream(ByteOutput byteOutput)

Create a OutputStream wrapper for a ByteOutput.

Parameters:

byteOutput - the byte output

Returns:

the output stream wrapper

nullExternalizerFactory

@Deprecated
public static ExternalizerFactory nullExternalizerFactory()

Deprecated. Use nullClassExternalizerFactory() instead.

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

Returns:

the null externalizer factory

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 java.io.OptionalDataException createOptionalDataException(boolean eof)

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

Parameters:

eof - true if there is no more data in the buffered part of the stream

Returns:

a new OptionalDataException

createOptionalDataException

public static java.io.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.

Returns:

the null externalizer
