public class NodeTypeDefDiff

extends Object

A NodeTypeDefDiff represents the result of the comparison of two node type definitions.

The result of the comparison can be categorized as one of the following types:

NONE inidcates that there is no modification at all.

A TRIVIAL modification has no impact on the consistency of existing content and does not affect existing/assigned definition id's. The following modifications are considered TRIVIAL:

• changing node type orderableChildNodes flag
• changing node type primaryItemName value
• adding non-mandatory property/child node
• changing property/child node protected flag
• changing property/child node onParentVersion value
• changing property/child node mandatory flag to false
• changing property/child node autoCreated flag
• changing child node defaultPrimaryType
• changing child node sameNameSiblings flag to true
• weaken property valueConstraints (e.g. by removing completely or by adding to existing or by making a single constraint less restrictive)
• changing property defaultValues

A MINOR modification has no impact on the consistency of existing content but does affect existing/assigned definition id's. The following modifications are considered MINOR:

• changing specific property/child node name to *
• weaken child node requiredPrimaryTypes (e.g. by removing)
• changing specific property requiredType to undefined
• changing property multiple flag to true

A MAJOR modification affects the consistency of existing content and does change existing/assigned definition id's. All modifications that are neither TRIVIAL nor MINOR are considered MAJOR.
