  - ### Method Detail

    - #### inflateBestEffort

          public static final byte[] inflateBestEffort(byte[] in)

      Returns an inflated copy of the input array. If the deflated input has been truncated or corrupted, a best-effort attempt is made to inflate as much as possible. If no data can be extracted `null` is returned.

    - #### inflateBestEffort

          public static final byte[] inflateBestEffort(byte[] in,
                                                       int sizeLimit)

      Returns an inflated copy of the input array, truncated to `sizeLimit` bytes, if necessary. If the deflated input has been truncated or corrupted, a best-effort attempt is made to inflate as much as possible. If no data can be extracted `null` is returned.

    - #### inflate

          public static final byte[] inflate(byte[] in)
                                      throws java.io.IOException

      Returns an inflated copy of the input array.
      Throws:
        `java.io.IOException` - if the input cannot be properly decompressed

    - #### deflate

          public static final byte[] deflate(byte[] in)

      Returns a deflated copy of the input array.
