Method Detail

feed

public Decoder<O> feed(InputBuffer input)

Description copied from class: Decoder

Incrementally decodes as much input buffer data as possible, and returns another Decoder that represents the continuation of how to decode additional buffer data. If isLast is true, then feed must return a terminated Decoder, i.e. a Decoder in the done state, or in the error state. The given input buffer is only guaranteed to be valid for the duration of the method call; references to input must not be stored.

Specified by:

feed in class Decoder<O>

fork

public Decoder<O> fork(Object condition)

Description copied from class: Decoder

Returns a Decoder continuation whose behavior may be altered by the given out-of-band condition.

Overrides:

fork in class Decoder<O>

bind

public O bind()

Description copied from class: Decoder

Returns the decoded result. Only guaranteed to return a result when in the done state.

Overrides:

bind in class Decoder<O>

trap

public Throwable trap()

Description copied from class: Decoder

Returns the decode error. Only guaranteed to return an error when in the error state.

Overrides:

trap in class Decoder<O>

doDecode

protected abstract Decoder<? extends O> doDecode()

Returns a new Decoder continuation for this DynamicDecoder, or null if this DynamicDecoder is done.

didDecode

protected abstract void didDecode(O value)

Lifecycle callback invoked after this DynamicDecoder has finished decoding a value.
