Examples of EmptyExpression

org.apache.slide.search.basic.expression.EmptyExpression
Represents an AND expression. @author Martin Wallmer @version $Revision: 1.2.2.1 $
org.codehaus.groovy.ast.expr.EmptyExpression
This class is a place holder for an empty expression. Empty expression are used in closures lists like (;). During class Generation this expression should be either ignored or reaplce with a null value. @author Jochen Theodorou @see org.codehaus.groovy.ast.stmt.EmptyStatement
org.exist.xquery.modules.ngram.query.EmptyExpression
org.mozilla.javascript.ast.EmptyExpression
AST node for an empty expression. Node type is {@link Token#EMPTY}.
To create an empty statement, wrap it with an {@link ExpressionStatement}.

Examples of com.github.sommeri.less4j.core.ast.EmptyExpression

    List<HiddenTokenAwareTree> children = actual.getChildren();
    String name = buildFunctionName(children.get(0));


    if (children.size() == 1) {
      /* No arguments to the function */
      return new FunctionExpression(token, name, new EmptyExpression(token));
    }


    HiddenTokenAwareTree parameterNode = children.get(1);


    Expression parameter = (Expression) parentBuilder.switchOn(parameterNode);
