Detailed Description

Represents a GVCP discovery command (DISCOVERY_CMD)

Constructor & Destructor Documentation

◆ GvcpDiscoveryRequestLayer() [1/2]

pcpp::GvcpDiscoveryRequestLayer::GvcpDiscoveryRequestLayer	(	uint8_t *	data,
		size_t	dataLen,
		Layer *	prevLayer,
		Packet *	packet
	)

inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in

◆ GvcpDiscoveryRequestLayer() [2/2]

pcpp::GvcpDiscoveryRequestLayer::GvcpDiscoveryRequestLayer	(	bool	allowBroadcastAck = `false`,
		bool	acknowledgeRequired = `true`,
		uint16_t	requestId = `1`
	)

explicit

A constructor that creates a new GVCP discovery command

Parameters

[in]	allowBroadcastAck	Whether the device is allowed to broadcast the acknowledge, optional
[in]	acknowledgeRequired	Whether an acknowledge is required, optional
[in]	requestId	The request ID, optional. The spec requires a non-zero value

Member Function Documentation

◆ hasAllowBroadcastAckFlag()

bool pcpp::GvcpDiscoveryRequestLayer::hasAllowBroadcastAckFlag ( ) const

Returns: True if the allow-broadcast-acknowledge bit is set in the flag, meaning the device is allowed to broadcast the acknowledge, false otherwise

◆ serializeLayer()

void pcpp::GvcpDiscoveryRequestLayer::serializeLayer ( ObjectScope & serializer ) const

overrideprotectedvirtual

Serializes the layer's data into a provided serializer object. This is used for generating serialized representations (like JSON) of the packet layers. This method should be overridden by derived layers to provide specific serialization logic.

Parameters

[in] serializer The object scope serializer to which the layer details should be written.

Reimplemented from pcpp::GvcpRequestLayer.

◆ setAllowBroadcastAckFlag()

void pcpp::GvcpDiscoveryRequestLayer::setAllowBroadcastAckFlag ( bool allowBroadcastAck )

Set or clear the allow-broadcast-acknowledge bit in the flag

Parameters

[in] allowBroadcastAck True to set the bit, false to clear it
