Examples with ASTNode org.codice.ddf.endpoints.ASTNode used on opensource projects

Example 1 with ASTNode

use of org.codice.ddf.endpoints.ASTNode in project ddf by codice.

the class OpenSearchQuery method addContextualFilter.

public void addContextualFilter(String searchTerm, String selectors) throws ParsingException {
    String methodName = "addContextualFilter";
    Filter filter = null;
    KeywordFilterGenerator keywordFilterGenerator = new KeywordFilterGenerator(filterBuilder);
    KeywordTextParser parser = Parboiled.createParser(KeywordTextParser.class);
    // translate the search terms into an abstract syntax tree
    ParsingResult<ASTNode> result = new RecoveringParseRunner(parser.inputPhrase()).run(searchTerm);
    // make sure it's a good result before using it
    if (result.matched && !result.hasErrors()) {
        filter = generateContextualFilter(selectors, keywordFilterGenerator, result);
    } else if (result.hasErrors()) {
        throw new ParsingException("Unable to parse keyword search phrase. " + generateParsingError(result));
    }
    if (filter != null) {
        filters.add(filter);
    }
}

Example 2 with ASTNode

use of org.codice.ddf.endpoints.ASTNode in project ddf by codice.

    Map<String, String> inputToOutput = new LinkedHashMap<String, String>();
    FilterBuilder filterBuilder = new GeotoolsFilterBuilder();

        KeywordFilterGenerator kfg = new KeywordFilterGenerator(filterBuilder);
        Filter filter = kfg.getFilterFromASTNode(result.resultValue);
        inputToOutput.put(input, filter.toString());
