Interface TokenDecoder

All Known Subinterfaces:

ComparableTokenDecoder

All Known Implementing Classes:

AbstractTokenDecoder, SparseRecordDecoder

public interface TokenDecoder

Converts binary encodings of tokens into token values. Implementations should extend AbstractTokenDecoder rather than implementing this interface directly.

Method Summary

Modifier and Type	Method	Description
void	decode(BinaryReader source, boolean skip)	Decodes the encoding at the current position of the reader and stores the value in the current target.
void	decodeField(BinaryReader source, int fieldIndex, boolean skip)	Decodes the encoding at the current position of the reader and stores the value in the current target.
void	setTarget(TokenSettable buffer)	Designates the current target for decoding operations.

Method Details

setTarget

void setTarget(TokenSettable buffer)

Designates the current target for decoding operations.

Parameters:

buffer - the target buffer into which to decode.

decode

void decode(BinaryReader source,
 boolean skip)

Decodes the encoding at the current position of the reader and stores the value in the current target. The reader is advanced past the encoding as a result.

Parameters:

source - the reader containing the encoding

skip - a value of true means decode the bytes but don't set on target

decodeField

void decodeField(BinaryReader source,
 int fieldIndex,
 boolean skip)

Decodes the encoding at the current position of the reader and stores the value in the current target. The reader is advanced past the encoding as a result.

Parameters:

source - the reader containing the encoding

fieldIndex - the index of the field being decoded

skip - a value of true means decode the bytes but don't set on target
