Interface EmptyReachableSetStep

All Superinterfaces:

ReachableSetStep

public interface EmptyReachableSetStep
extends ReachableSetStep

An empty (and incomplete) reachable set step. To complete the step, start by defining a "from" part using either from(String) or fromConfigurationItemType(). After completing the step (defining "from", "to" and "link" parts), you will be able to add another step or return to the containing node. Leaving the reachable set step in an incomplete state will result in an invalid query definition.

Note: This interface extends ReachableSetStep to aid automatic query builders, so the following idiom can be used:

 ReachableSetStep step = node.reachableSetDefinition().addstep();
 step.from().ofType(x);
 step.to().ofType(y);
 step.link().ofType(z).setAlongDirection(true);

However, for explicit step creation, it's usually easier (and more readable) to use the chained methods approach.

Since:

UCMDB 9.0

Method Detail

from

ReachableSetStepFromPart from(String typeName)

Defines a "from type" condition for this step. Only steps that start with the given type will be a valid match for this step definition.

Returns:

the "from" part of the step.

fromITWorldType

ReachableSetStepFromPart fromITWorldType()

Deprecated. use fromConfigurationItemType()

fromConfigurationItemType

ReachableSetStepFromPart fromConfigurationItemType()

Defines a "from any type" condition for this step. The same as calling from("configuration_item");

Returns:

the "from" part of the step.
