Constructor Detail

EngineConfigurationImpl

public EngineConfigurationImpl(SessionCoordinator sessionCoordinator,
                               ConcurrencySettings concurrencySettings)

Creates a new EngineConfiguration object using the specified SessionCoordinator and concurrency settings. If this constructor is used the engine will be configured to check perform documents contain known activities but full schema validation of the perform documents will not be performed.

Parameters:

sessionCoordinator - The SessionCoordinator that will be used by the engine for joining and releasing requests to and from sessions.

concurrencySettings - Concurrency settings for the engine.

Throws:

java.lang.IllegalArgumentException - If

• factory is null;
• sessionCoordinator is null;
• concurrencySettings is null;
