Traversal Strategies

Identifier:

com.ibm.xtools.emf.validation.core.traversalStrategies

Since:

7.0.5

Description:

Allows clients to contribute a custom traversal strategy that will be used when validation core executes batch validation. Batch validation occurs during resource load, calls to ValidationManager#executeValidation and constraint enablement.

This allows clients to provide specialized handling in these circumstances. By default the strategy used traverses the proper contents of the object and ignores unloaded resources and objects.

API Information:

Supplied Implementation:

The platform itself does not have any predefined traversalStrategies. Particular product installs may include traversalStrategies as required.
