The ASTIterator interface defines the functionality required by the enginer, for compiletime and runtime operations. Unlike other script implementations, MVEL does not use a completely normalized AST tree for it's execution. Instead, nodes are organized into a linear order and delivered via this iterator interface, much like bytecode instructions.

Examples of org.hibernate.hql.internal.ast.util.ASTIterator

    if ( fromElement.getQueryableCollection() != null && fromElement.isFetch() ) {
      text = fromElement.renderCollectionSelectFragment( nonscalarSize, k );
      appender.append( SqlTokenTypes.SQL_TOKEN, text, false );
    }
    // Look through the FromElement's children to find any collections of values that should be fetched...
    ASTIterator iter = new ASTIterator( fromElement );
    while ( iter.hasNext() ) {
      FromElement child = ( FromElement ) iter.next();
      if ( child.isCollectionOfValuesOrComponents() && child.isFetch() ) {
        // Need a better way to define the suffixes here...
        text = child.renderValueCollectionSelectFragment( nonscalarSize, nonscalarSize + k );
        appender.append( SqlTokenTypes.SQL_TOKEN, text, false );
