Examples of org.activiti.cdi.spi.ProcessEngineLookup

org.activiti.cdi.spi.ProcessEngineLookup

Represents a strategy for building or looking up a {@link ProcessEngine}.

Implementations of this class are looked up using the Java SE 6 {@link ServiceLoader}facilities. Users of this class that provide a custom implementation, must declare it in a file named META-INF/services/org.activiti.cdi.spi.ProcessEngineLookup in order for it to be found.

Each implementation declares a "precedence". The precedence controls the order in which the resolved implementations will be invoked. (See: getPrecedence().) Implementations with a higher precedence will we invoked first.
