Method Detail

makeFilter

public AllFilter makeFilter(Object oLeft,
                            Object oRight)

Description copied from class: BaseOperator

Create a Filter for this BaseOperator using the specified left and right values.

Note: This method should be thread safe as operators are stored in a static map so may be called by multiple threads.

Overrides:

makeFilter in class BaseOperator<AllFilter>

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

addToTokenTable

public void addToTokenTable(TokenTable tokenTable)

Description copied from class: BaseOperator

Add this operator to the given TokenTable. This typically means adding this operator using its symbol and also adding any aliases.

Specified by:

addToTokenTable in class BaseOperator<AllFilter>

Parameters:

tokenTable - the TokenTable to add this operator to

populateFilterArray

protected void populateFilterArray(Filter[] aFilterDest,
                                   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 AllFilter then rather than adding the AllFilter itself to the target array all of the filters contained within the AllFilter are added to the array.

Parameters:

aFilterDest - the Filter array to be populated

aFilterSrc - the outer filter to add to the array
