      Modifier and Type Method Description
      void add​(int offset, java.lang.String s)
      Modifies the string table to add a string at a specified offset, growing the internal byte[] storage as necessary to accommodate the string at the offset.
      void clear()  
      int getByteCount()  
      java.lang.String getStringAtOffset​(long offset)
      Returns the string found at offset, or throws an IOException if the offset is out of bounds.
      boolean isValid​(long offset)
      Returns true if the specified offset is a valid offset for this string table.
      static StringTable readStringTable​(ByteProvider bp)

      • getByteCount

        public int getByteCount()

      • add

        public void add​(int offset,
                java.lang.String s)
        Modifies the string table to add a string at a specified offset, growing the internal byte[] storage as necessary to accommodate the string at the offset.

        Used for unit tests to construct a custom string table for test cases.

        Parameters:
        offset - where to place the string in the table
        s - string to insert into table
