Examples of JBitSet

org.apache.derby.iapi.util.JBitSet
JBitSet is a wrapper class for BitSet. It is a fixed length implementation which can be extended via the grow() method. It provides additional methods to manipulate BitSets. NOTE: JBitSet was driven by the (current and perceived) needs of the optimizer, but placed in the util package since it is not specific to query trees.. NOTE: java.util.BitSet is final, so we must provide a wrapper class which includes a BitSet member in order to extend the functionality. We want to make it look like JBitSet extends BitSet, so we need to provide wrapper methods for all of BitSet's methods. @author Jerry Brenner

    // about eqOuterCols, so just create a zero-length array, pretending
