Overrides:

makeFilter in class BaseOperator<AnyFilter>

Parameters:

oLeft - the left value to use to build a Filter

oRight - the right value to use to build a Filter

Returns:

a Filter representing this operation

Specified by:

addToTokenTable in class BaseOperator<AnyFilter>

Parameters:

tokenTable - the TokenTable to add this operator to

populateFilterArray

                                   Filter... aFilterSrc)

Populate the specified target Filter array with the Filters in the source array.

If the any of the Filters in the source array is an AnyFilter then rather than adding the AnyFilter itself to the target array all of the filters contained within the AnyFilter are added to the array.

Parameters:
