getFields
Class: matlab.net.http.HeaderField
Namespace: matlab.net.http
Return header fields matching name or class
Description
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 | matlab.metadata.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 whoseName
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
matlab.metadata.Class
objects that are subclasses ofHeaderField
.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 theHeaderField.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}
.
