Example 1 with CopyFilterDelegate

use of ddf.catalog.filter.delegate.CopyFilterDelegate in project ddf by codice.

                // Define the extra query clause(s) to add to the copied filter
                // This will create a filter with a search phrase of:

Example 2 with CopyFilterDelegate

use of ddf.catalog.filter.delegate.CopyFilterDelegate in project ddf by codice.

the class DummyPreSubscriptionPlugin method process.

    Subscription newSubscription = input;
    if (input != null) {
        FilterDelegate<Filter> delegate = new CopyFilterDelegate(filterBuilder);

            Filter modifiedFilter = filterBuilder.allOf(copiedFilter, extraFilter);
            // Create a new subscription with the modified filter
            newSubscription = new SubscriptionImpl(modifiedFilter, input.getDeliveryMethod(), input.getSourceIds(), input.isEnterprise());
        } catch (UnsupportedQueryException e) {
