    • parseObject

      public void parseObject(String fileName, ParserListenerMode mode, org.antlr.v4.runtime.ParserRuleContext ctx)
      Parses a database object from the given parse tree context.
      Parameters:
      fileName - the source file being parsed
      mode - the parsing mode (REF, SCRIPT, etc.)
      ctx - the ANTLR parse tree context to parse from

    • parseObject

      public abstract void parseObject()
      Parses a database object from the current context. Must be implemented by concrete subclasses to handle specific object types.

      public static String getFullCtxText(org.antlr.v4.runtime.ParserRuleContext ctx)
      Extracts raw text from context
      Parameters:
      ctx - context
      Returns:
      raw string

    • getFullCtxText

      public static String getFullCtxText(org.antlr.v4.runtime.ParserRuleContext start, org.antlr.v4.runtime.ParserRuleContext end)
      Extracts raw text between two parse tree contexts.
      Parameters:
      start - the starting context
      end - the ending context
      Returns:
      the text between the contexts

      Extracts raw text between two tokens.
      Parameters:
      start - the starting token
      end - the ending token
      Returns:
      the text between the tokens

      public static ArgMode parseArgMode(org.antlr.v4.runtime.ParserRuleContext mode)
      Parses an argument mode from a parse tree context.
      Parameters:
      mode - the mode parse tree context
      Returns:
      the parsed ArgMode

    • getSafe

      public <T extends IStatement, R extends IStatement> R getSafe(BiFunction<T,String,R> getter, T container, org.antlr.v4.runtime.ParserRuleContext ctx)
      Safely retrieves a database statement with validation.

      Note: Always returns null if parser is in ref mode.

      Type Parameters:

      ctx - the parse tree context
      Returns:
      the found statement or null if parser is in ref mode
      Throws:
      UnresolvedReferenceException - if statement not found
