Examples of com.hazelcast.spi.Operation

com.hazelcast.spi.Operation
An operation could be compared the a {@link Runnable}. So it contains logic that is going to be executed; this logic will be placed in the {@link #run()} method.

    public void addOperation(Operation op) {
        if (op instanceof TxnRemoveOperation) {
            TxnRemoveOperation removeOperation = (TxnRemoveOperation) op;
            Iterator<Operation> iter = opList.iterator();
            while (iter.hasNext()) {
                Operation opp = iter.next();
                if (opp instanceof TxnPutOperation) {
                    TxnPutOperation putOperation = (TxnPutOperation) opp;
                    if (putOperation.getRecordId() == removeOperation.getRecordId()) {
                        iter.remove();
                        return;
                    }
                }
            }
        } else if (op instanceof TxnRemoveAllOperation) {
            TxnRemoveAllOperation removeAllOperation = (TxnRemoveAllOperation) op;
            Collection<Long> recordIds = removeAllOperation.getRecordIds();
            Iterator<Operation> iter = opList.iterator();
            while (iter.hasNext()) {
                Operation opp = iter.next();
                if (opp instanceof TxnPutOperation) {
                    TxnPutOperation putOperation = (TxnPutOperation) opp;
                    if (recordIds.remove(putOperation.getRecordId())) {
                        iter.remove();
