Method Detail

getLeafUnitNodes

default List<ExpressionNode> getLeafUnitNodes()

Gets all the leaf units of the expression tree. A leaf unit is a node with at least one leaf node as its child. For example, Name eq 'John' is a leaf unit within a bigger filter expression tree.

Parameters:

filterTreeNode - Represents the filter expression tree

Returns:

A list of leaf units from the filter expression tree

getNodes

default List<ExpressionNode> getNodes()

Gets all the nodes from a filter expression tree.

Parameters:

filterTree - An ExpressionNode object which is the root node of a filter expression tree

Returns:

A list of ExpressionNode objects containing all nodes of a given filter expression tree
