                     int off,
                     int len)

setInput

public void setInput(byte[] b)

setDictionary

public void setDictionary(byte[] b,

setStrategy

public void setStrategy(int strategy)

setLevel

public void setLevel(int level)

needsInput

public boolean needsInput()

flush

public void flush()

When called, indicates that the current input buffer contents should be flushed out when deflate is next called.

fullFlush

public void fullFlush()

When called, indicates that the current input buffer contents should be flushed out when deflate is next called, but all compression information up to this point is cleared.

finish

When called, indicates that compression should end with the current contents of the input buffer. Deflate must be called to get the final compressed bytes.

finished

public boolean finished()

getTotalOut

public int getTotalOut()

reset

public void reset()

end

public void end()

finalize

protected void finalize()

Overrides:

finalize in class java.lang.Object
