Method Detail

getByteWriter

public ByteWriter getByteWriter(ByteWriterFactory.Longevity longevity,
                                ByteWriterFactory.EncryptionStatus encryption,
                                ByteWriterFactory.Fixed fixed,
                                long size,
                                boolean fast)

Description copied from interface: ByteWriterFactory

Request a single ByteWriter with the given properties. An implementation is free to ignore the properties or to use them in any way that it views appropriate in choosing the right kind of ByteWriter to return. These should be viewed as "advice" to the implementation about the intended usage.

Specified by:

getByteWriter in interface ByteWriterFactory

Parameters:

longevity - anticipated lifetime of the ByteWriter

encryption - encryption status of the data to be placed into the ByteWriter

fixed - whether the size given is the maximum data that will ever be placed into the ByteWriter

size - either the maximum size of the data or an estimate of the size depending on the value of the fixed parameter

fast - the requested ByteWriter needs to be fast

Returns:

a ByteWriter matching your properties to some degree of "match"

                                  ByteWriterFactory.Fixed fixed,
                                  long[] size,
                                  boolean fast)

closeByteWriter

public void closeByteWriter(ByteWriter byteWriter)
                     throws IOException

Description copied from interface: ByteWriterFactory

The caller has finished with the given ByteWriter and will no longer use it again. The implementation can close it.

Specified by:

closeByteWriter in interface ByteWriterFactory

Parameters:

byteWriter - a no longer needed ByteWriter

Throws:

IOException

See Also:

ByteWriterFactory.closeByteWriter(com.adobe.internal.io.ByteWriter)

closeFactory

public void closeFactory()
                  throws IOException

Description copied from interface: ByteWriterFactory

The ByteWriterFactory is no longer needed and it should close down and free all resources allocated. All ByteWriter instances created by this factory can and may be destroyed during this process.

Specified by:

closeFactory in interface ByteWriterFactory

Throws:

IOException
