Method Detail

getRuntimeDataMap

java.util.Map getRuntimeDataMap()

Returns mappings that determine the values of action properties and flow context variables at runtime. The sources for these runtime data mappings include flow context variables and runtime configuration properties. The targets for these runtime data mappings include flow context variables and action properties.

By default, each action has a set of properties that are determined when a flow chart is created. However, some flow charts require an action property to be set at runtime, using data that is generated or acquired dynamically. A runtime data mapping from a flow context variable to an action property provides the necessary functionality to set an action property at runtime using data generated or acquired at runtime.

For example, suppose a FileExistTrigger monitors *.txt files. When that trigger fires, the name of the file that it discovered needs to be passed into a subsequent action for processing. The name of this file is not known until runtime. In this case, a runtime property mapping must be set.

Similarly, some action properties should be stored in a central location. A central storage location allows a property that exists in many actions to be updated globally in one step. For example, if many jobs each contain an EjbSessionAction with a common PROVIDER_URL property, that PROVIDER_URL property can be updated in all jobs in a single step, if that property is stored in a central location, such as the runtime configuration tree.

Furthermore, some flow context variables need to be copied to other flow context variables. For example, if two actions flow into a third action and a join point exists at that third action, the flow context result variables can be copied into new locations in the joined flow context. This runtime data mapping provides this functionality and makes it possible to condense flow context data from multiple sources into a joined flow context.

Returns:

Map of AbstractRuntimeDataMapSource to AbstractRuntimeDataMapTarget. A runtime data map describes how data is mapped from a source to a target. If the returned map is changed, the changes are reflected back into this Flow object.

Parameters:

runtimeDataMap - Map of AbstractRuntimeDataMapSource to AbstractRuntimeDataMapTarget. A runtime data map describes how data is mapped from a source to a target. If the passed in map is changed, the changes are reflected back into this Flow object.
