      Modifier and Type Method Description
      boolean equalTo​(Slime that)
      Tests whether the two Inspectors are equal.
      Cursor get()
      Get a Cursor connected to the top-level data object.
      int insert​(java.lang.String name)
      Add a name to the symbol table; if the name is already in the symbol table just returns the id it already had.

      Return the symbol name associated with an id.
      int lookup​(java.lang.String name)
      Find the id associated with a symbol name; if the name was not in the symbol table returns the constant Integer.MAX_VALUE instead.
