Field Detail

_attrMap

protected int[] _attrMap

Int-based compact data structure that contains mapping from attribute names to attribute indexes in the main attribute name array.

Data structure contains two separate areas; main hash area (with size _hashAreaSize), and remaining spillover area that follows hash area up until (but not including) _spillAreaEnd index. Main hash area only contains indexes (index+1; 0 signifying empty slot) to actual attributes; spillover area has both hash and index for any spilled entry. Spilled entries are simply stored in order added, and need to be searched using linear search. In case of both primary hash hits and spills, eventual comparison with the local name needs to be done with actual name array.

_hashAreaSize

protected int _hashAreaSize

Size of hash area in _attrMap; generally at least 20% more than number of attributes (_attrCount).

_spillAreaEnd

protected int _spillAreaEnd

Pointer to int slot right after last spill entry, in _attrMap array.

Method Detail

startNewValue

public char[] startNewValue(PName attrName,
                            int currOffset)

Method called by the parser right after attribute name has been parsed, but before value has been parsed.

Returns:

Underlying character buffer to use for storing attribute value characters

continueValue

public char[] continueValue()

finishLastValue

public final int finishLastValue(int endingOffset)

Method called after all attribute entries have been parsed, and thus the end of the last value in the buffer is known.

Returns:

Number of attributes collected

finishLastValue2

public final int finishLastValue2()

valueBufferFull

public char[] valueBufferFull()

Method called by the owner, when the
