Constructor Detail

DeflaterPool

public DeflaterPool(int capacity,
                    int compressionLevel,
                    boolean nowrap)

Create a Pool of Deflater instances.

If given a capacity equal to zero the Deflaters will not be pooled and will be created on acquire and ended on release. If given a negative capacity equal to zero there will be no size restrictions on the DeflaterPool

Parameters:

capacity - maximum number of Deflaters which can be contained in the pool

compressionLevel - the default compression level for new Deflater objects

nowrap - if true then use GZIP compatible compression for all new Deflater objects
