Overview

An NSRangeSpecifier object specifies a range (that is, an uninterrupted series) of objects in a container through two delimiting objects. The range is represented by two object specifiers, a start specifier and an end specifier, which can be of any specifier type (such as NSIndexSpecifier or NSWhoseSpecifier object). These specifiers are evaluated in the context of the same container object as the range specifier itself.

You don’t normally subclass NSRangeSpecifier.

Tasks

Initializing a Range Specifier

Accessing a Range Specifier

Instance Methods

endSpecifier

Returns the object specifier representing the last object of the range.

- (NSScriptObjectSpecifier *)endSpecifier

Return Value

The object specifier representing the last object of the range.

Availability

Available in Mac OS X v10.0 and later.

initWithContainerClassDescription:containerSpecifier:key:startSpecifier:endSpecifier:

Returns a range specifier initialized with the given properties.

- (id)initWithContainerClassDescription:(NSScriptClassDescription *)classDescription containerSpecifier:(NSScriptObjectSpecifier *)container key:(NSString *)property startSpecifier:(NSScriptObjectSpecifier *)startSpec endSpecifier:(NSScriptObjectSpecifier *)endSpec

Parameters

classDescription: The class description.
container: The container.
property: The property.
startSpec: The object specifier representing the first object of the range.
endSpec: The object specifier representing the last object of the range.

Return Value

A range specifier initialized with the given properties.

Discussion

Invokes the super class’s initWithContainerClassDescription:containerSpecifier:key: method and initializes the instance with the object specifiers representing the starting element, startSpec, and the ending element, endSpec, of a range of elements in the container.
