A ProcessingMechanism is a type of
Mechanism that transforms its input in some way. A ProcessingMechanism always
receives its input either from another ProcessingMechanism, or from the input to a Process or System when it is
executed. Similarly, its output is generally conveyed to another ProcessingMechanism or used as the ouput for a Process
or System. However, the output of a ProcessingMechanism may also be used by an AdaptiveMechanism
to modify the parameters of other components (or its own). ProcessingMechanisms are always executed before all
AdaptiveMechanisms in the Process and/or System to which they belong, so that any modificatons made by the
AdaptiveMechanism are available to all ProcessingMechanisms in the next
Creating a ProcessingMechanism¶
A ProcessingMechanism can be created by using the standard Python method of calling the constructor for the desired
type. Some types of ProcessingMechanism (for example, ObjectiveMechanisms) are also created
when a System or Process is created, if
control have been specified for it.
A ProcessingMechanism has the same basic structure as a Mechanism. See the documentation for individual subtypes of ProcessingMechanism for more specific information about their structure.
