Buffer read-only attributes
Use buffer read-only attributes to access the information contained in an existing buffer. The following
attributes are available per reading buffer (for example, rb.basetimeseconds would access
basetimeseconds for reading buffer rb, and the number of readings the reading buffer can store is
accessed as rb.capacity).
The fractional portion of the timestamp of when the reading at rb[1] was
stored in the reading buffer (in seconds).
The seconds portion of the timestamp, in whole seconds, when the reading at
rb[1] was stored in the buffer.
The total number of readings that can be stored in the reading buffer.
The timestamp resolution, in seconds. The resolution is fixed at 1e-9 seconds.
Buffer programming examples
Refer to the following for buffer control programming examples. In the example, the buffer is named
readingbuffer.
You must clear the buffer using the readingbuffer.clear() command before changing buffer
control attributes.
readingbuffer.collectchannels = 1
readingbuffer.appendmode = 1
Enable the buffer append mode.
readingbuffer.collecttimestamps = 0
Disable timestamp storage.
Refer to the following for buffer read-only attribute programming examples. In the example, the buffer
is named readingbuffer.
Request number of readings stored in the
buffer.
buffer_size = readingbuffer.capacity
Request the buffer storage capacity.
