Compressed stream classes

CompressedInputStream and CompressedOutputStream allow you to apply a compression Codec to an input or output stream.

Factory

The CompressedInputStream$create() and CompressedOutputStream$create() factory methods instantiate the object and take the following arguments:

• stream An InputStream or OutputStream, respectively

• codec A Codec, either a Codec instance or a string

• compression_level compression level for when the codec argument is given as a string

Methods

Methods are inherited from InputStream and OutputStream, respectively
