Examples of java.util.zip.Deflater.deflate()

java.util.zip.Deflater.deflate()
Fills specified buffer with compressed data. Returns actual number of bytes of compressed data. A return value of 0 indicates that needsInput() should be called in order to determine if more input data is required. @param b the buffer for the compressed data @param off the start offset of the data @param len the maximum number of bytes of compressed data @return the actual number of bytes of compressed data
