    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(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.
    String
    inspect(int symbol)
    Return the symbol name associated with an id.
    int
    lookup(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.
    Cursor
    setArray()
    Create a new array value and make it the new top-level data object.
    Cursor
    setBool(boolean bit)
    Create a new boolean value and make it the new top-level data object.
    Cursor

    Create a new data value and make it the new top-level data object.
    Cursor
    setDouble(double d)
    Create a new double value and make it the new top-level data object.
    Cursor
    setLong(long l)
    Create a new double value and make it the new top-level data object.
    Cursor
    setNix()
    Create a new empty value and make it the new top-level data object.
    Cursor
    setObject()
    Create a new object value and make it the new top-level data object.
    Cursor
    setString(byte[] utf8)
    Create a new string value and make it the new top-level data object.
    Cursor
    setString(String str)
    Create a new string value and make it the new top-level data object.
    int
    symbols()
    Returns a count of names in the symbol table.
    String
    toString()
     
    Cursor
    wrap(int sym)
    Take the current top-level data object and make it a field in a new ObjectValue with the given symbol id as field id; the new ObjectValue will also become the new top-level data object.
