| int read(byte[] buf int off int len): | Reads uncompressed data into an array of bytes. If len is not zero the method will block until some input can be decompressed; otherwise no bytes are read and 0 is returned. Syntax : public int read(byte[] buf int off int len) throws IOException Overrides: read in class InflaterInputStream Parameters: buf - the buffer into which the data is read off - the start offset in the destination array b len - the maximum number of bytes read Returns: the actual number of bytes read or -1 if the end of the compressed input stream is reached Throws: NullPointerException IndexOutOfBoundsException ZipException IOException
