MqttVariableHeader class - mqtt_client library

Constructors

MqttVariableHeader(): Initializes a new instance of the MqttVariableHeader class.
MqttVariableHeader.fromByteBuffer(MqttByteBuffer headerStream): Initializes a new instance of the MqttVariableHeader class, populating it with data from a stream.

Properties

connectFlags ↔ MqttConnectFlags: Conenct flags
getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
keepAlive ↔ int: Defines the maximum allowable lag, in seconds, between expected messages. The spec indicates that clients won't be disconnected until KeepAlive + 1/2 KeepAlive time period elapses.
getter/setter pair
length ↔ int: The length, in bytes, consumed by the variable header.
getter/setter pair
messageIdentifier ↔ int?: Message identifier
getter/setter pair
protocolName ↔ String: Protocol name
getter/setter pair
protocolVersion ↔ int: Protocol version
getter/setter pair
returnCode ↔ MqttConnectReturnCode: Return code
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.

topicName ↔ String: Topic name
getter/setter pair

Methods

getWriteLength() → int: Gets the length of the write data when WriteTo will be called. A subclass that overrides writeTo must also overwrite this method.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
readConnectFlags(MqttByteBuffer stream) → void: Connect flags
readFrom(MqttByteBuffer variableHeaderStream) → void: Creates a variable header from the specified header stream. A subclass can override this method to do completely custom read operations if required.
readKeepAlive(MqttByteBuffer stream) → void: Keep alive
readMessageIdentifier(MqttByteBuffer stream) → void: Message identifier
readProtocolName(MqttByteBuffer stream) → void: Read functions Protocol name
readProtocolVersion(MqttByteBuffer stream) → void: Protocol version
readReturnCode(MqttByteBuffer stream) → void: Return code
readTopicName(MqttByteBuffer stream) → void: Topic name
toString() → String: A string representation of this object.
inherited
writeConnectFlags(MqttByteBuffer stream) → void: Connect flags
writeKeepAlive(MqttByteBuffer stream) → void: Keep alive
writeMessageIdentifier(MqttByteBuffer stream) → void: Message identifier
writeProtocolName(MqttByteBuffer stream) → void: Write functions Protocol name
writeProtocolVersion(MqttByteBuffer stream) → void: Protocol version
writeReturnCode(MqttByteBuffer stream) → void: Return code
writeTo(MqttByteBuffer variableHeaderStream) → void: Writes the variable header to the supplied stream. A subclass can override this method to do completely custom write operations if required.
writeTopicName(MqttByteBuffer stream) → void: Topic name

Operators

operator ==(Object other) → bool: The equality operator.
