Metadata Class

Metadata Class

A collection of metadata entries that can be exchanged during a call. gRPC supports these types of metadata:

Request headers - are sent by the client at the beginning of a remote call before any request messages are sent.
Response headers - are sent by the server at the beginning of a remote call handler before any response messages are sent.
Response trailers - are sent by the server at the end of a remote call along with resulting call status.

Copy

public sealed class Metadata : IList<MetadataEntry>, 
	ICollection<MetadataEntry>, IEnumerable<MetadataEntry>, IEnumerable

Public NotInheritable Class Metadata
	Implements IList(Of MetadataEntry), ICollection(Of MetadataEntry), 
	IEnumerable(Of MetadataEntry), IEnumerable

public ref class Metadata sealed : IList<MetadataEntry^>, 
	ICollection<MetadataEntry^>, IEnumerable<MetadataEntry^>, IEnumerable

[<SealedAttribute>]
type Metadata =  
    class
        interface IList<MetadataEntry>
        interface ICollection<MetadataEntry>
        interface IEnumerable<MetadataEntry>
        interface IEnumerable
    end
