    • getSignature

      public String getSignature()
      Description copied from class: AbstractQueryModelNode
      Default implementation of QueryModelNode.getSignature() that prints the name of the node's class.
      Specified by:
      getSignature in interface QueryModelNode
      getSignature in class AbstractQueryModelNode
      The node's signature, e.g. SLICE (offset=10, limit=10).
    • equals

      public boolean equals(Object other)
      Description copied from interface: QueryModelNode
      Returns true if this query model node and its children are recursively equal to o and its children.
