Return header fields matching name or class - MATLAB

Syntax

[fields,indices] = getFields(headers,ids)

Description

[fields,indices] = getFields(headers,ids) returns fields and their indices in the header fields that match the given IDs.

Input Arguments

`headers` — Header fields
vector of `matlab.net.http.HeaderField` objects

Header fields, specified as a vector of matlab.net.http.HeaderField objects.

`ids` — Names to match
strings | `matlab.net.http.HeaderField` objects | `meta.class` objects

Names to match, specified as one of the following.

String vector, character vector, cell array of character vectors, or comma-separated list of strings or character vectors containing the names of the fields to return. Names are not case-sensitive.
Vector or comma-separated list of one or more matlab.net.http.HeaderField objects whose Name properties are used to determine which fields to return. Names are not case-sensitive. Header field values in these objects are ignored.
Vector or comma-separated list of meta.class objects that are subclasses of HeaderField.
The getFields method searches for names that match names supported by the specified classes, regardless of the class. If a subclass does not have a specific set of supported names, all header fields of that subclass are matched regardless of their names. Call the HeaderField.displaySubclasses method to see supported names.

Output Arguments

`fields` — Fields matching input
array of `matlab.net.http.HeaderField` objects

Fields matching input, returned as an array of matlab.net.http.HeaderField objects. If no matches exist, getFields returns an empty HeaderField array. The name search is case-insensitive.

`indices` — Index values of fields
array of integers | `[]`

Index values of fields, returned as an array of integers, or [] if no match.

If messages is a vector, then getFields returns fields matching ids from all messages. indices is a cell array of vectors, where indices{i} contains the indices of the matching fields in messages{i}.
