len
is not zero, the method will block until some input can be decompressed; otherwise, no bytes are read and 0
is returned. If this method returns a nonzero integer n then buf[off]
through buf[off+
n-1]
contain the uncompressed data. The content of elements buf[off+
n]
through buf[off+
len-1]
is undefined, contrary to the specification of the InputStream
superclass, so an implementation is free to modify these elements during the inflate operation. If this method returns -1
or throws an exception then the content of buf[off]
through buf[off+
len
-1]
is undefined.
