Example 1 with TextMatching

use of annis.model.QueryNode.TextMatching in project ANNIS by korpling.

the class AnnotationConditionProvider method addAnnotationConditions.

/**

 * @param annotation The annotation to add
 * @param table Table to operate on

Example 2 with TextMatching

use of annis.model.QueryNode.TextMatching in project ANNIS by korpling.

the class DefaultWhereClauseGenerator method addSpanConditions.

@Override
protected void addSpanConditions(List<String> conditions, QueryData queryData, QueryNode node) {
    TextMatching textMatching = node.getSpanTextMatching();
    conditions.add(join(textMatching.sqlOperator(), tables(node).aliasedColumn(NODE_TABLE, "span"), sqlString(node.getSpannedText(), textMatching)));
}
