Constructor & Destructor Documentation

◆ Message() [1/3]

xsens::Message::Message	(	const uint8_t	msgId = `0`,
		const uint16_t	length = `0`,
		const uint16_t	maxLength = `CMT_MAXMSGLEN`
	)

Create a Message object with the given data length and message Id.

The function allocates enough memory to hold an entire message with the given data length.

Parameters

msgId	The message Id that will be assigend to the m_messageId field.
length	The length of the data in the message. This value is stored in `m_createdLength` as well as `m_length` or `m_extendedLength`.
maxLength	The maximum data length that can be stored in the structure.

Definition at line 41 of file cmtmessage.cpp.

◆ Message() [2/3]

xsens::Message::Message	(	const uint8_t *	source,
		const uint16_t	size,
		const uint16_t	maxLength = `CMT_MAXMSGLEN`
	)

Create a message from the given source string.

This is done through a simple memory copy. The number of bytes copied is taken from the data in the message (so the message is interpreted first). Note that this does NOT recompute the checksum, nor is it checked.

Parameters

source	The source string containing message data
size	The size of the source string
maxLength	The maximum data length that can be stored in the structure.
