        QueryRootNode createQueryTree​(java.lang.String statement,
                              NameResolver resolver,
                              QueryNodeFactory factory)
                       throws InvalidQueryException

        Parameters:
        statement - the statement.
        resolver - the name resolver to use.
        factory - the query node factory to use.
        Returns:
        the QueryNode tree for the statement.
        Throws:
        InvalidQueryException - if the statement is malformed.

        boolean canHandle​(java.lang.String language)
        Returns true if this query tree builder can handle a statement in language.
        Parameters:
        language - the language of a query statement to build a query tree.
        Returns:
        true if this builder can handle language; false otherwise.

        Returns:
        String array containing the names of the supported languages.

      • toString

        java.lang.String toString​(QueryRootNode root,
                          NameResolver resolver)
                   throws InvalidQueryException
        Creates a String representation of the query node tree in the syntax this QueryTreeBuilder can handle.
        Parameters:
        root - the root of the query node tree.
        resolver - to resolve Names.
        Returns:
        a String representation of the query node tree.
        Throws:
        InvalidQueryException - if the query node tree cannot be converted into a String representation due to restrictions in this syntax.
