Constructor Detail

MultiBinaryLongMap.LeftoverLongMapHolder.LeftoverMaskedBinaryLongMap

public MultiBinaryLongMap.LeftoverLongMapHolder.LeftoverMaskedBinaryLongMap(MultiBinaryLongMap.MaskedLongMapHolder holder,
                                                                            BinaryLongMap blm,
                                                                            int cShift,
                                                                            int cBits)

Construct a LeftoverMaskedBinaryLongMap.

Parameters:

holder - the MaskedLongMapHolder

blm - the underlying BinaryLongMap

cShift - the number of positions to left-shift the values stored in this MaskedBinaryLongMap

cBits - the number of bits in the values stored in this MaskedBinaryLongMap

Method Detail

encode

protected long encode(long lEncoded,
                      long lValue)

Encode the specified n-bit value into the possibly already encoded value, preserving any unrelated bits.

Overrides:

encode in class MultiBinaryLongMap.MaskedBinaryLongMap

Parameters:

lEncoded - the 64-bit value to encode into

lValue - the value to encode

Returns:

the new encoded value

instantiateMaskedEntryVisitor

protected MultiBinaryLongMap.MaskedBinaryLongMap.MaskedEntryVisitor instantiateMaskedEntryVisitor(BinaryLongMap.EntryVisitor visitor,
                                                                                                  boolean fExisting)

Instantiate a MaskedEntryVisitor to use to MultiBinaryLongMap.MaskedBinaryLongMap.visit(com.tangosol.util.Binary, com.tangosol.util.BinaryLongMap.EntryVisitor) entries in this MaskedBinaryLongMap.

Overrides:

instantiateMaskedEntryVisitor in class MultiBinaryLongMap.MaskedBinaryLongMap

Parameters:

visitor - the underlying visitor to wrap

fExisting - true iff the underlying visitor is to visit only entries that logically exist in the MaskedBinaryLongMap

Returns:

a MaskedEntryVisitor
