Summary

Public constructors
`SimpleMetadataDecoder()`

Public functions
`Metadata?`	`decode(inputBuffer: MetadataInputBuffer!)` Decodes a `Metadata` element from the provided input buffer.

Protected functions
`abstract Metadata?`	`decode(inputBuffer: MetadataInputBuffer!, buffer: ByteBuffer!)` Called by `decode` after input buffer validation has been performed.

SimpleMetadataDecoder()

fun decode(inputBuffer: MetadataInputBuffer!): Metadata?

Decodes a Metadata element from the provided input buffer.

Respects limit of inputBuffer.data, but assumes position and arrayOffset are both zero and hasArray is true.

Parameters
`inputBuffer: MetadataInputBuffer!`	The input buffer to decode.

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

protected abstract fun decode(inputBuffer: MetadataInputBuffer!, buffer: ByteBuffer!): Metadata?

Called by decode after input buffer validation has been performed.

Parameters
`inputBuffer: MetadataInputBuffer!`	The input buffer to decode.
`buffer: ByteBuffer!`	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.
