Method Detail

• public int addFragment(byte[] fragment)

  Adds a fragment for reassembly. A fragment may fail to be added if the reassembly is already complete, or if the fragment is malformed.

  Returns:

  fragment ID of the fragment, if accepted, -1 on failure.

• public byte[] getData()

  Gets the reassembled data, if reassembly is complete.

  Returns:

  reassembled data, or null if reassembly incomplete.

• public long getDataLength()

  Gets length of the data array to reassemble.

  Returns:

  data array length in bytes.

• public int getFragmentCount()

  Gets the number of fragments successfully added during reassembly.

  Returns:

  number of fragments successfully added.

• public int getFragmentLength()

  Gets length of each fragment.

  Returns:

  fragment length in bytes.

• public int getMaxFragmentCount()

  Gets the maximum number of fragments possible.

  Returns:

  maximum number of fragments possible.

• public int getMinFragmentCount()

  Gets the minimum number of fragments required to reassemble the data.

  Returns:

  minimum number of fragments required.

• public boolean hasFinishedReassembly()

  Checks if the reassemble is complete.

  Returns:

  true if reassembly is done, false if more fragments are required.

• public Reassembler setup(long dataLen, int fragmentLen)

  Sets up the reassembler to reassemble a large data chunk from smaller fragments of a specified length.

  Parameters:

  dataLen - length of the large data chuck to be reconstructed.

  fragmentLen - size of each fragment in bytes.
