Detailed Description

Routines for demarshaling data.

All demarshal*() methods will advance the internal data pointer the correct number of bytes to read the next piece of data.

◆ is_valid()

void Demarshaling::is_valid ( uint32_t  numBytesWanted)
private

Checks to make sure that we're not overruing any array via an assertion.

Parameters
numBytesWantedThe number of bytes that we want to pull out of the array.

◆ set_data()

void DBus::Demarshaling::set_data ( const uint8_t *  data,
uint32_t  dataLen 
)

Set the data C array to marshal/demarshal.

This also has the side effect of resetting the data offset to 0, in cases where you are demarshaling data.

Parameters
data

◆ set_data_offset()

void Demarshaling::set_data_offset ( uint32_t  offset)

Set the offset in the data to demarshal.

Parameters
offset
