matlab.net.http.HeaderField.displaySubclasses

Class: matlab.net.http.HeaderField
Namespace: matlab.net.http

Display supported HeaderField subclasses

Syntax

matlab.net.http.HeaderField.displaySubclasses

[fields,names] = matlab.net.http.HeaderField.displaySubclasses

Description

matlab.net.http.HeaderField.displaySubclasses displays all subclasses of the HeaderField class in the matlab.net.http.field namespace and the names of the header fields they support. Use these subclasses to construct common header fields.

example

[fields,names] = matlab.net.http.HeaderField.displaySubclasses returns the subclass names in fields as an array of strings. The method returns the header field names that the subclasses support in names, a cell array of string vectors that the subclasses support. names{i} contains the names supported by fields(i). If fields(i) has no constraints on supported names, then names{i} is empty.
