Detailed Description

template<typename T>
class adtf::streaming::ant::sample_data< T >

Sample Data getter for an easy use of samples with samplebuffer set to the type T.

Template Parameters

T	type of content of the samples sample buffer to get via GetData or sample_data::operator::T

Remarks

as long a sample data holds an reference to a sample the buffer is read locked !

Please use the newer versions (sample_data) from the flash namespace.

GetTime()

template<typename T>

tTimeStamp GetTime ( ) const

inline

Returns

returns the sample data time

Return values

-1	no time set

Definition at line 68 of file sample_data.h.

IsValid()

template<typename T>

bool IsValid ( ) const

inline

Validate if sample and sample buffer is set.

Return values
