Class ASTNode

java.lang.Object
org.parboiled.trees.ImmutableGraphNode<ASTNode>
org.parboiled.trees.ImmutableTreeNode<ASTNode>
org.parboiled.trees.ImmutableBinaryTreeNode<ASTNode>
org.codice.ddf.opensearch.endpoint.ASTNode
All Implemented Interfaces:
org.parboiled.trees.BinaryTreeNode<ASTNode>, org.parboiled.trees.GraphNode<ASTNode>, org.parboiled.trees.TreeNode<ASTNode>
Direct Known Subclasses:
KeywordASTNode, OperatorASTNode, PhraseDelimiterASTNode
public abstract class ASTNode extends org.parboiled.trees.ImmutableBinaryTreeNode<ASTNode>
Abstract Syntax Tree Node
Abstract class that extends built-in Parboiled tree node class.

During the parsing of the keyword string, the parser creates and stores instances of this class's subclasses on the processing stack. This allows the parser to build an Abstract Syntax Tree from the keyword string.
