Constructor Detail

ItemStateValidator

public ItemStateValidator(ManagerProvider mgrProvider,
                          PathFactory pathFactory)

Creates a new ItemStateValidator instance.

Parameters:

mgrProvider - manager provider

Method Detail

validate

public void validate(NodeState nodeState)
              throws ConstraintViolationException,
                     RepositoryException

Checks whether the given node state satisfies the constraints specified by its primary and mixin node types. The following validations/checks are performed:

• check if its node type satisfies the 'required node types' constraint specified in its definition
• check if all 'mandatory' child items exist
• for every property: check if the property value satisfies the value constraints specified in the property's definition

Parameters:

nodeState - state of node to be validated

Throws:

ConstraintViolationException - if any of the validations fail

RepositoryException - if another error occurs
