deflate

public int deflate(int flush)

Overrides:

deflate in class ZStream

end

public int end()

Description copied from class: ZStream

Those methods are expected to be override by Inflater and Deflater. In the future, they will become abstract methods.

Overrides:

end in class ZStream

Returns:

zlib error code

params

public int params(int level,
 int strategy)

setDictionary

public int setDictionary(byte[] dictionary,
 int dictLength)

finished

public boolean finished()

Overrides:

finished in class ZStream

copy

public int copy(Deflater src)

deflateBound

public int deflateBound(int sourceLen)

Calculate pessimistic deflate bound (copied from C ZLib code)

Parameters:

sourceLen - source data length

Returns:

maximum size of compressed data
