Examples with ColumnSet org.apache.accumulo.core.iterators.conf.ColumnSet used on opensource projects

Example 1 with ColumnSet

use of org.apache.accumulo.core.iterators.conf.ColumnSet in project teiid by teiid.

the class BaseFilterIterator method init.

@Override
public void init(SortedKeyValueIterator<Key, Value> source, Map<String, String> options, IteratorEnvironment env) throws IOException {
    super.init(source, options, env);
    String cf = options.get(AccumuloMetadataProcessor.CF);
    String cq = options.get(AccumuloMetadataProcessor.CQ);
    if (options.get(AccumuloMetadataProcessor.VALUE_IN) != null) {
        String value = options.get(AccumuloMetadataProcessor.VALUE_IN);
        this.valueIn = AccumuloMetadataProcessor.ValueIn.valueOf(value.substring(1, value.length() - 1));
    } else {
        this.valueIn = AccumuloMetadataProcessor.ValueIn.VALUE;
    }
    if (cq != null) {
        // $NON-NLS-1$
        this.columnFilter = new ColumnSet(Arrays.asList(cf + ":" + cq));
    } else {
        this.columnFilter = new ColumnSet(Arrays.asList(cf));
    }
    this.negate = false;
    if (options.get(NEGATE) != null) {
        this.negate = Boolean.parseBoolean(options.get(NEGATE));
    }
