COSStandardOutputStream

public COSStandardOutputStream(OutputStream out,
                               long position)

Constructor.

Parameters:

out - The underlying stream to write to.

position - The current position of output stream.

Method Detail

getPos

public long getPos()

This will get the current position in the stream.

Returns:

The current position in the stream.

isOnNewLine

public boolean isOnNewLine()

This will tell if we are on a newline.

Returns:

true If we are on a newline.

setOnNewLine

public void setOnNewLine(boolean newOnNewLine)

This will set a flag telling if we are on a newline.

Parameters:

newOnNewLine - The new value for the onNewLine attribute.
