public LikeFilter makeFilter(Object oLeft,
                             Object oRight)

Overrides:

makeFilter in class BaseOperator<LikeFilter>

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

Specified by:

addToTokenTable in class BaseOperator<LikeFilter>

Parameters:

tokenTable - the TokenTable to add this operator to

isIgnoreCase

protected boolean isIgnoreCase()

Returns true if the LikeFilter should be case-insensitive, otherwise returns false.
