Class NodeTypeDefDiff

java.lang.Object

org.apache.jackrabbit.oak.plugins.nodetype.NodeTypeDefDiff

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 indicates that there is no modification at all.

A TRIVIAL modification has no impact on the consistency of existing content. 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 specific property/child node name to *
• changing child node defaultPrimaryType
• changing child node sameNameSiblings flag to true
• weaken child node requiredPrimaryTypes (e.g. by removing)
• weaken property valueConstraints (e.g. by removing a constraint or by making a specific constraint less restrictive)
• changing property defaultValues
• changing specific property requiredType to undefined
• changing property multiple flag to true

A MAJOR modification potentially affects the consistency of existing content. All modifications that are not TRIVIAL are considered MAJOR.

This class duplicates code from org.apache.jackrabbit.spi.commons.nodetype.NodeTypeDefDiff; both should be updated in sync, see OAK-2802
