Method Detail

getInstance

public static RuntimeDelegate getInstance()

Obtain a RuntimeInstance instance. If an instance had not already been created and set via setInstance(RuntimeDelegate), the first invocation will create an instance which will then be cached for future use.

The algorithm used to locate the RuntimeInstance subclass to use consists of the following steps:

• If a resource with the name of META-INF/services/org.centeropenmiddleware.almistack.poc.clients.spi.RuntimeInstance exists, then its first line, if present, is used as the UTF-8 encoded name of the implementation class.
• If the $java.home/lib/poc-business-logic.properties file exists and it is readable by the java.util.Properties.load(InputStream) method and it contains an entry whose key is org.centeropenmiddleware.almistack.poc.clients.spi.RuntimeInstance, then the value of that entry is used as the name of the implementation class.
• If a system property with the name org.centeropenmiddleware.almistack.poc.clients.spi.RuntimeInstance is defined, then its value is used as the name of the implementation class.
• Finally, a default implementation class name is used.

Returns:

an instance of RuntimeInstance.

setInstance

public static void setInstance(RuntimeDelegate delegate)

Set the runtime delegate that will be used by Client Business Logic API classes. If this method is not called prior to getInstance() then an implementation will be sought as described in getInstance().

Parameters:

delegate - the RuntimeInstance runtime delegate instance.

Throws:

SecurityException - if there is a security manager and the permission ReflectPermission("suppressAccessChecks") has not been granted.
