        Specified by:
        getClassType in interface DebuggerColumn<java.lang.String>
        Returns:
        Java type of this column

        Description copied from interface: DebuggerColumn
        Gets title of the column.
        Specified by:

        Specified by:
        setValue in interface DebuggerColumn<java.lang.String>
        Parameters:
        location - memory address (not row in debug table)
        value - new value of the cell

      • getValue

        public java.lang.String getValue​(int location)
        Get opcode for instruction at specific location.
        Specified by:

        Parameters:
        location - memory address (not row in debug table)
        Returns:
        Opcode string of an instruction at specific location

      • getDefaultWidth

        public int getDefaultWidth()
        Description copied from interface: DebuggerColumn
        Get default width of the column in pixels. If it is not known, this method should return -1.
        Specified by:
