Field Detail children protected List<QueryNode> children(Code) id protected int id(Code) parent protected QueryNode parent(Code) Constructor Detail QueryNode protected QueryNode()(Code) Default constructor QueryNode protected QueryNode(int id)(Code) Protected constructor. Parameters:   id - the node ID Method Detail addChild public void addChild(QueryNode child)(Code) Add a new child node after the last child. Parameters:   child - The child node to be added addChild public void addChild(QueryNode parentNode, QueryNode child)(Code) Add a new child to the given parent node. The parent node may be the current node, or any of its immediate or transitive child nodes. Parameters:   parentNode - The parent node where the child should be inserted Parameters:   child - The child node to be added addChildAfter public void addChildAfter(QueryNode afterNode, QueryNode child)(Code) Add a child after the given node. The after node may be an immediate or transitive child of the current node. Parameters:   afterNode - node after which the child should be inserted Parameters:   child - child node to be added buildSqlQuery abstract protected void buildSqlQuery(SqlQueryBuilder builder)(Code) Build the query represented by this node and its children. Parameters:   builder - an sql query builder equals public boolean equals(Object anotherNode)(Code) findChild public QueryNode findChild(int childId)(Code) Return the child node with the given ID. Parameters:   childId - the requested child node ID the child node with the given ID getChild public QueryNode getChild(int index)(Code) Return the child node at the given index. Parameters:   index - the child index in this parent's children list the child node at the given index. getChildren public List<QueryNode> getChildren()(Code) getId public int getId()(Code) getLabel public FxString getLabel()(Code) Return the label to be displayed for this query node. the label to be displayed for this query node. getLevel public int getLevel()(Code) Return the nesting level of the given node in the query tree, i.e. the number of parent links one has to traverse to reach the root node. A node attached to the root node has a level of 1. the node level getNodeName protected String getNodeName()(Code) Return the informal representation of a node to be used in toString. the informal representation of a node to be used in toString. getParent public QueryNode getParent()(Code) getPath public String getPath()(Code) Returns the complete node path of the current node, i.e. the node ids traversed to the root node separated by dashes ("-"). e.g. 1.path --> 1 |- 2.path --> 1-2 |- 3.path --> 1-2-3 the complete node path of the current node hashCode public int hashCode()(Code) isHidden public boolean isHidden()(Code) Returns true if the node and its children should not be displayed in a query editor or report. true if the node and its children should not be displayed isValid abstract public boolean isValid()(Code) Return true if the node's value is valid, or false if it is not. true if the node's value is valid, or false if it is not. isValueNode public boolean isValueNode()(Code) Return true if this node is a "value" node, i.e. is used to represent a scalar value in the query. Used for JSTL node handling. true for scalar value nodes isWideInput public boolean isWideInput()(Code) Returns true if the node needs a wide input field, e.g. a datepicker or file download field. true if the node needs a wide input field removeChild public QueryNode removeChild(QueryNode child)(Code) Remove a child node. Also searches all subtrees if the node is node an immediate child. Parameters:   child - the child to be deleted the parent node of the deleted child, or null if the child does not exist setChildren public void setChildren(List<QueryNode> children)(Code) setId public void setId(int id)(Code) setParent public void setParent(QueryNode parent)(Code) Set the parent of this node. If the node is not included in the parent's children list, it is added automatically.
