48.12 Functions for Checking the Validity of Specifier Components

Function: valid-specifier-domain-p domain

This function returns non-nil if domain is a valid specifier domain. A domain is used to instance a specifier (i.e. determine the specifier’s value in that domain). Valid domains are a window, frame, or device. (nil is not valid.)

Function: valid-specifier-locale-p locale

This function returns non-nil if locale is a valid specifier locale. Valid locales are a device, a frame, a window, a buffer, and global. (nil is not valid.)

Function: valid-specifier-locale-type-p locale-type

Given a specifier locale-type, this function returns non-nil if it is valid. Valid locale types are the symbols global, device, frame, window, and buffer. (Note, however, that in functions that accept either a locale or a locale type, global is considered an individual locale.)

Function: valid-specifier-type-p specifier-type

Given a specifier-type, this function returns non-nil if it is valid. Valid types are generic, integer, boolean, color, font, image, face-boolean, and toolbar.

Function: valid-specifier-tag-p tag

This function returns non-nil if tag is a valid specifier tag.

Function: valid-instantiator-p instantiator specifier-type

This function returns non-nil if instantiator is valid for specifier-type.

Function: valid-inst-list-p inst-list type

This function returns non-nil if inst-list is valid for specifier type type.

Function: valid-spec-list-p spec-list type

This function returns non-nil if spec-list is valid for specifier type type.

Function: check-valid-instantiator instantiator specifier-type

This function signals an error if instantiator is invalid for specifier-type.

Function: check-valid-inst-list inst-list type

This function signals an error if inst-list is invalid for specifier type type.

Function: check-valid-spec-list spec-list type

This function signals an error if spec-list is invalid for specifier type type.
