A pin provides values to actions and accept result values from them. A pin is an object node for inputs and outputs to actions.

An input pin is a pin that holds input values to be consumed by an action.

An action input pin is a kind of pin that executes an action to determine the values to input to another.

An input pin is a pin that holds input values to be consumed by an action.

A pin provides values to actions and accept result values from them. A pin is an object node for inputs and outputs to actions.

An output pin is a pin that holds output values produced by an action.

A pin provides values to actions and accept result values from them. A pin is an object node for inputs and outputs to actions.

An input pin is a pin that holds input values to be consumed by an action.

A value pin is an input pin that provides a value by evaluating a value specification.

An object node is an abstract activity node that is part of defining object flow in an activity. Object nodes have support for token selection, limitation on the number of tokens, specifying the state required for tokens, and carrying control values.

An activity parameter node is an object node for inputs and outputs to activities.

An object node is an abstract activity node that is part of defining object flow in an activity. Object nodes have support for token selection, limitation on the number of tokens, specifying the state required for tokens, and carrying control values.

A central buffer node is an object node for managing flows from multiple sources and destinations.

An object node is an abstract activity node that is part of defining object flow in an activity. Object nodes have support for token selection, limitation on the number of tokens, specifying the state required for tokens, and carrying control values.

A central buffer node is an object node for managing flows from multiple sources and destinations.

A data store node is a central buffer node for non-transient information.

An object node is an abstract activity node that is part of defining object flow in an activity. Object nodes have support for token selection, limitation on the number of tokens, specifying the state required for tokens, and carrying control values.

An expansion node is an object node used to indicate a flow across the boundary of an expansion region. A flow into a region contains a collection that is broken into its individual elements inside the region, which is executed once per element. A flow out of a region combines individual elements into a collection for use outside the region.
