Class BranchNode

    • Field Detail

      • children

        protected List<ExprNode> children
        child node list for this branch node

    • Constructor Detail

      • BranchNode

        protected BranchNode​(AssertionType assertionType,
                     List<ExprNode> childList)
        Creates a BranchNode using a logical operator and a list of children.
        Parameters:
        assertionType - the node's type
        childList - the child nodes under this branch node.

      • BranchNode

        protected BranchNode​(AssertionType assertionType,
                     ExprNode... childList)
        Creates a BranchNode using a logical operator and a list of children.
        Parameters:
        assertionType - the node's type
        childList - the child nodes under this branch node.

      • BranchNode

        protected BranchNode​(AssertionType assertionType)
        Creates a BranchNode using a logical operator.
        Parameters:
        assertionType - the node's type

    • Method Detail

      • isLeaf

        public final boolean isLeaf()
        Description copied from interface: ExprNode
        Tests to see if this node is a leaf or branch node.
        Returns:
        false all the time.
        See Also:
        ExprNode.isLeaf()

      • clone

        public ExprNode clone()
        Makes a full clone in new memory space of the current node and children
        Specified by:
        clone in interface ExprNode
        Overrides:
        clone in class AbstractExprNode
        Returns:
        the clone

      • addNode

        public void addNode​(ExprNode node)
        Adds a child node to this branch node node
        Parameters:
        node - the child expression to add to this branch node

      • addNodeToHead

        public void addNodeToHead​(ExprNode node)
        Adds a child node to this branch node at the head rather than the tail.
        Parameters:
        node - the child expression to add to this branch node

      • getChildren

        public List<ExprNode> getChildren()
        Gets the children below this BranchNode. We purposefully do not clone the array list so that backends can sort the order of children using their own search optimization algorithms. We want backends and other parts of the system to be able to induce side effects on the tree structure.
        Returns:
        the list of child nodes under this branch node.

      • setChildren

        public void setChildren​(List<ExprNode> list)
        Sets the list of children under this node.
        Parameters:
        list - the list of children to set.

      • getFirstChild

        public ExprNode getFirstChild()
        Convenience method that gets the first child in the children array. Its very useful for NOT nodes since they only have one child by avoiding code that looks like: ( ExprNode ) m_children.get( 0 )
        Returns:
        the first child

      • accept

        public final Object accept​(FilterVisitor visitor)
        Description copied from interface: ExprNode
        Element/node accept method for visitor pattern.
        Parameters:
        visitor - the filter expression tree structure visitor
        Returns:
        The modified element
        See Also:
        ExprNode.accept( FilterVisitor)

      • isSchemaAware

        public boolean isSchemaAware()
        Tells if this Node is Schema aware.
        Returns:
        true if the Node is SchemaAware
