Decodes a Metadata element from the provided input buffer.

public EventMessageDecoder()

public EventMessage decode(ParsableByteArray emsgData)

protected Metadata decode(MetadataInputBuffer inputBuffer, ByteBuffer buffer)

Called by decode after input buffer validation has been performed.

Parameters
`MetadataInputBuffer inputBuffer`	The input buffer to decode.
`ByteBuffer buffer`	The input buffer's `data buffer`, for convenience. Validation by decode guarantees that `hasArray`, `position` and `arrayOffset` are `true`, `0` and `0` respectively.

Returns
`Metadata`	The decoded metadata object, or `null` if the metadata could not be decoded.
