Constructors

Msg()

Constructs new message and allocates unique ID

Declaration
protected Msg()

Properties

ArrivalTimeStamp

Returns arrival timestamp expressed in ticks, that is - when message just arrived before its processing started by Glue (before deserialization). This property allows for glue-internal latency assessment

Declaration
public long ArrivalTimeStamp { get; }
Property Value
Type Description
System.Int64

BindingSpecificContext

Returns a binding-specific context object which is used for message processing/routing by binding. This property value is not serialized and used internally by Glue framework. Not all bindings use/need this property

Declaration
public object BindingSpecificContext { get; }
Property Value
Type Description
System.Object

CorrelationData

Arbitrary named object collection that can be used to correlate messages and/or attach extra data. This field is NOT transmitted over wire nor is it used by the framework. Message inspectors may use this property at their own discretion, for example in cases when the same inspector type is registered on multiple levels (endpoint, binding, glue), inspectors may check this property to execute only once per message. The collection is lazily allocated at the first reference attempt

Declaration
public Dictionary<string, object> CorrelationData { get; }
Property Value
Type Description
System.Collections.Generic.Dictionary<System.String, System.Object>

HasCorrelationData

Returns true when this message contains header data

Declaration
public bool HasCorrelationData { get; }
Property Value
Type Description
System.Boolean

HasHeaders

Returns true when this message contains header data

Declaration
public bool HasHeaders { get; }
Property Value
Type Description
System.Boolean

Headers

Returns a list of headers that this message contains

Declaration
public Headers Headers { get; set; }
Property Value
Type Description
Headers

ID

Returns a unique ID for this message

Declaration
public FID ID { get; }
Property Value
Type Description
FID

RequestID

Returns request ID that relates to this message instance. It is the message ID for RequestMsg and related message ID for ResponseMsg

Declaration
public abstract FID RequestID { get; }
Property Value
Type Description
FID

Methods

__SetArrivalTimeStampTicks(Int64)

Framework method not for developers. Sets arrival ticks stamp. Usually called from transport

Declaration
public void __SetArrivalTimeStampTicks(long value)
Parameters
Type Name Description
System.Int64 value

__SetBindingSpecificContext(Msg)

Internal method not to be called by app developers. Called from custom bindings to inject binding-specific context

Declaration
public void __SetBindingSpecificContext(Msg other)
Parameters
Type Name Description
Msg other

__SetBindingSpecificContext(Object)

Internal method not to be called by app developers. Called from custom bindings to inject binding-specific context

Declaration
public void __SetBindingSpecificContext(object context)
Parameters
Type Name Description
System.Object context

CloneState(Msg, Boolean, Boolean)

Clones message state from another message instance. State includes binding-specific context and optionally headers and correlation data

Declaration
public void CloneState(Msg from, bool cloneHeaders = true, bool cloneCorrelation = true)
Parameters
Type Name Description
Msg from
System.Boolean cloneHeaders
System.Boolean cloneCorrelation

ToString()

Declaration
public override string ToString()
Returns
Type Description
System.String
Overrides
System.Object.ToString()
