Interface ContextAssociationManager

All Known Implementing Classes:

Represents a means for associating an execution with a context.

This enables activiti-cdi to provide contextual business process management services, without relying on a specific context like i.e. the conversation context.

getCachedVariables

VariableMap getCachedVariables()

Returns:

a VariableMap of process variables cached between flushes

setVariableLocal
