Constructor Details

ByteChunkDeferred

public ByteChunkDeferred(String namePrefix,
 int chunkId,
 Types.MAPIType type)

Creates a Byte Stream Chunk, with the specified type.

Method Details

readValue

public void readValue(DocumentNode node)

Links the chunk to a document

Parameters:

node - the document node

readValue

public void readValue(InputStream value)
               throws IOException

Description copied from class: Chunk

Reads the value of this chunk using an InputStream

Overrides:

readValue in class ByteChunk

Throws:

IOException

writeValue

public void writeValue(OutputStream out)
                throws IOException

Description copied from class: Chunk

Writes the value of this chunk back out again.

Overrides:

writeValue in class ByteChunk

Throws:

IOException

getValue

public byte[] getValue()

Get bytes directly.

Overrides:

getValue in class ByteChunk

setValue

public void setValue(byte[] value)

Set bytes directly.

updating the linked document node/msg file directly would be unexpected, so we remove the link and act as a ByteChunk from then

Overrides:

setValue in class ByteChunk
