pack-priv Class EndstreamFilterStream

extends Object
Class Inheritance
This class is only for the readUntilEndStream method, to prevent a final CR LF or LF (but not a final CR!) from being written to the output, unless the beginning of the stream is assumed to be ASCII. This solves PDFBOX-2079 and PDFBOX-2120 and avoids making readUntilEndStream() even more complex than it already is.

public long calculateLength()

write out a single CR if one was kept. Don't write kept CR LF or LF, and then call the base method to flush.

filterback to summary
public void filter(byte[] b, int off, int len)

Write CR and/or LF that were kept, then writes len bytes from the specified byte array starting at offset off to this output stream, except trailing CR, CR LF, or LF. No filtering will be done for the entire stream if the beginning is assumed to be ASCII.

Parameters
b:byte[]

byte array.

off:int

offset.

len:int

length of segment to write.
