  • get

    public final java.lang.Object get()

    Description copied from class: Location
    Get the current value of this location.

    Specified by:

    get in class Location<java.lang.Object>

  • isBound

    public boolean isBound()

    Specified by:

    isBound in class Location<java.lang.Object>

  • set

    public final void set(java.lang.Object newValue)

    Specified by:

    set in class Location<java.lang.Object>

  • getPropertyList

    public static java.lang.Object getPropertyList(java.lang.Object symbol,
     Environment env)

    Get the property list assocated with an object in a given Environment.

    Parameters:

    symbol - Usually but not necessarily a Symbol. (A String is not converted a Symbol by this method.)

  • getPropertyList

    public static java.lang.Object getPropertyList(java.lang.Object symbol)

    Get the property list associated with object in the current Environment. Corresponds to Common Lisp's symbol-plist function.

    Parameters:

    symbol - Usually but not necessarily a Symbol. (A String is not converted a Symbol by this method.)

  • setPropertyList

    public static void setPropertyList(java.lang.Object symbol,
     java.lang.Object plist,
     Environment env)

    Set the property list assocated with an object in a given Environment. This function should be avoided, since a Symbol's property list may be used by unknown classes. It also can be slow.

    Parameters:

    symbol - Usually but not necessarily a Symbol. (A String is not converted a Symbol by this method.)

  • setPropertyList

    public static void setPropertyList(java.lang.Object symbol,
     java.lang.Object plist)

    Set the property list assocated with an object in a given Environment. Corresponds to Common Lisp's (setf symbol-plist) function.

    See Also:

    setPropertyList(Object,Object,Environment)

  • getProperty

    public static java.lang.Object getProperty(java.lang.Object symbol,
     java.lang.Object property,
     java.lang.Object defaultValue,
     Environment env)

    Gets a property value associated with an object.

    Parameters:

    symbol - Usually a Symbol, but can be any Object. A String is converted to a Symbol using env.getSymbol(). Symbols require a constant-type hash lookup; other object are searched linearly.

  • getProperty

    public static java.lang.Object getProperty(java.lang.Object symbol,
     java.lang.Object property,
     java.lang.Object defaultValue)

    Gets a property value associated with an object. Corresponds to Common Lisp's get function.

    See Also:

    getProperty(Object,Object,Object,Environment)

  • putProperty

    public static void putProperty(java.lang.Object symbol,
     java.lang.Object property,
     java.lang.Object newValue,
     Environment env)

  • putProperty

    public static void putProperty(java.lang.Object symbol,
     java.lang.Object property,
     java.lang.Object newValue)

    Sets a property value associated with an object. Corresponds to Common Lisp's (setf get) function.

  • removeProperty

    public static boolean removeProperty(java.lang.Object symbol,
     java.lang.Object property,
     Environment env)

    Remove a properaty assocatied with an object.

  • removeProperty

    public static boolean removeProperty(java.lang.Object symbol,
     java.lang.Object property)

    Remove a property associated with an object. Corresponds to Common Lisp's remprop function.

  • plistGet

    public static java.lang.Object plistGet(java.lang.Object plist,
     java.lang.Object prop,
     java.lang.Object dfault)

    Given a property list and a key, find the corresponding property value.

  • plistPut

    public static java.lang.Object plistPut(java.lang.Object plist,
     java.lang.Object prop,
     java.lang.Object value)

    Modify and add a property binding to a property list.

    Returns:

    The updated property list.

  • plistRemove

    public static java.lang.Object plistRemove(java.lang.Object plist,
     java.lang.Object prop)

    Remove a property binding from a property list.

    Returns:

    The updated property list.
