Deprecated. - replace with computeDifferenceForSamePartitionTuples

Parameters:

minuendTuple - -

subtrahendTuple - -

intervalTypedAttributesIntervalOperatorImplementations - -

attributeIntervalTypeImplementations - -

wrkArgList - A List object that can be used for parameter passing in internal invocations of other operators. Prevents having to re-allocate new working objects on each invocation.

wrkSet1 - -

wrkSet2 - -

Returns:

true if the tuples overlapped

computeDifferenceForSamePartitionTuples

public static java.util.Collection<TupleBuffer> computeDifferenceForSamePartitionTuples(TupleBuffer minuendTuple,
                                                                                        TupleBuffer subtrahendTuple,
                                                                                        MyReadOnlyLinkedHashMap<NameIdentifier,java.util.Map<java.lang.String,OperatorImplementation_V0104>> intervalTypedAttributesIntervalOperatorImplementations,
                                                                                        java.util.Map<NameIdentifier,IntervalTypeImplementation> attributeIntervalTypeImplementations)

Computes the USING difference between two given tuples

Parameters:

minuendTuple - The first tuple, to be range-diff'ed with the second

subtrahendTuple - The second tuple, to be range-diff'ed to the first. subtrahendTuple is presumed to have equal attribute values to minuendTuple for all attributes not mentioned in the ranges argument (intervalTypedAttributesIntervalOperatorImplementations).

intervalTypedAttributesIntervalOperatorImplementations - A map mapping the attribute names to a corresponding collection of interval operators (this collection takes itself the form of a mapping from operator names to interval operator implementations). The map is required to hold at least the OPERATORNAMES.SPLITBY, OPERATORNAMES.IMINUS, OPERATORNAMES.IINTERSECT and OPERATORNAMES.ISEMPTYINTERVAL implementations for each attribute.

attributeIntervalTypeImplementations - A map mapping the attribute names to a corresponding collection of interval type implementations

Returns:

The set of tuples covering all the points covered by minuendTuple but not by subtrahendTuple

computeDifferenceForSamePartitionTuples

public static java.util.Collection<TupleBuffer> computeDifferenceForSamePartitionTuples(TupleBuffer minuendTuple,
                                                                                        TupleBuffer subtrahendTuple,

Computes the USING difference between two given tuples

Parameters:

minuendTuple - The first tuple, to be range-diff'ed with the second

subtrahendTuple - The second tuple, to be range-diff'ed to the first. subtrahendTuple is presumed to have equal attribute values to minuendTuple for all attributes not mentioned in the ranges argument (intervalTypedAttributesIntervalOperatorImplementations).

intervalTypedAttributesIntervalOperatorImplementations - A map mapping the attribute names to a corresponding collection of interval operators (this collection takes itself the form of a mapping from operator names to interval operator implementations). The map is required to hold at least the OPERATORNAMES.SPLITBY, OPERATORNAMES.IMINUS, OPERATORNAMES.IINTERSECT and OPERATORNAMES.ISEMPTYINTERVAL implementations for each attribute.

attributeIntervalTypeImplementations - A map mapping the attribute names to a corresponding collection of interval type operator implementations.

wrkArgList - A work object that can be used for argument value passing in internal operator calls, sparing out the need to allocate a new argument list object internally for each invocatio of this method

Returns:

The set of tuples covering all the points covered by minuendTuple but not by subtrahendTuple
