void |
add(java.lang.String s)
Append data to the stream
|
java.io.OutputStream |
getBufferOutputStream()
Returns an OutputStream that can be used to write to the buffer which is used
to build up the PDF stream.
|
java.io.Writer |
getBufferWriter()
Returns a Writer that writes to the OutputStream of the buffer.
|
int |
getDataLength()
Returns the size of the content.
|
protected int |
getSizeHint()
Returns a value that hints at the size of the encoded stream.
|
int |
output(java.io.OutputStream stream)
Overload the base object method so we don't have to copy
byte arrays around so much
Write the PDF represention of this object
|
protected void |
outputRawStreamData(java.io.OutputStream out)
Sends the raw stream data to the target OutputStream.
|
void |
setData(byte[] data)
Used to set the contents of the PDF stream.
