OPERATOR
mem --- store and recall objects
DESCRIPTION
The mem operator is a method of storing object data for later use in an
igraph. It is a fire-on-any operator, meaning that it will produce an output
whenever any of its two input tokens are present. If an input object (any
type) arrives at the top port, mem stores the object data and passes the
object to its output port. The fireOnLoad parameter can prevent the object
from being sent to the output when loaded. Later, if a token (any type, any
value) arrives at the loadFlag port, the stored object is again sent to the
output. The mem operator is required in cases where the same object is used
many times within an igraph. For example, the getData operator can be used to
define a region of interest where measurements are to be made over a large
set of images. In such a case, the roi can be stored using the mem operator
and recalled for each measurement.
