    if (srcRightTuples.getInsertSize() > 32 && rtm instanceof AbstractHashTable) {
        ((AbstractHashTable) rtm).ensureCapacity(srcRightTuples.getInsertSize());

                    // so any existing leftTuples we know are updates, but only add if not already added
                    if (leftTuple.getStagedType() == LeftTuple.NONE) {
                        trgLeftTuples.addUpdate(leftTuple);

Example 2 with AbstractHashTable

use of org.drools.core.util.AbstractHashTable in project drools by kiegroup.

the class PhreakJoinNode method doRightInserts.

public void doRightInserts(JoinNode joinNode, LeftTupleSink sink, BetaMemory bm, InternalWorkingMemory wm, TupleSets<RightTuple> srcRightTuples, TupleSets<LeftTuple> trgLeftTuples) {
    TupleMemory ltm = bm.getLeftTupleMemory();
    TupleMemory rtm = bm.getRightTupleMemory();
    ContextEntry[] contextEntry = bm.getContext();
    BetaConstraints constraints = joinNode.getRawConstraints();
    if (srcRightTuples.getInsertSize() > 32 && rtm instanceof AbstractHashTable) {
        ((AbstractHashTable) rtm).ensureCapacity(srcRightTuples.getInsertSize());
    }
    for (RightTuple rightTuple = srcRightTuples.getInsertFirst(); rightTuple != null; ) {
        RightTuple next = rightTuple.getStagedNext();
        rtm.add(rightTuple);
        if (ltm != null && ltm.size() > 0) {
            FastIterator it = joinNode.getLeftIterator(ltm);
            constraints.updateFromFactHandle(contextEntry, wm, rightTuple.getFactHandleForEvaluation());
            for (LeftTuple leftTuple = joinNode.getFirstLeftTuple(rightTuple, ltm, it); leftTuple != null; leftTuple = (LeftTuple) it.next(leftTuple)) {
                if (leftTuple.getStagedType() == LeftTuple.UPDATE) {
                    // ignore, as it will get processed via left iteration. Children cannot be processed twice
                    continue;
                }
                if (constraints.isAllowedCachedRight(contextEntry, leftTuple)) {
