Example 17 with NodeDefinition

use of javax.jcr.nodetype.NodeDefinition in project jackrabbit by apache.

the class ItemSaveOperation method validateTransientItems.

/**
     * the following validations/checks are performed on transient items:
     *
     * for every transient item:
     * - if it is 'modified' or 'new' check the corresponding write permission.
     * - if it is 'removed' check the REMOVE permission
     *
     * for every transient node:
     * - if it is 'new' check that its node type satisfies the
     *   'required node type' constraint specified in its definition
     * - check if 'mandatory' child items exist
     *
     * for every transient property:
     * - check if the property value satisfies the value constraints
     *   specified in the property's definition
     *
     * note that the protected flag is checked in Node.addNode/Node.remove
     * (for adding/removing child entries of a node), in
     * Node.addMixin/removeMixin/setPrimaryType (for type changes on nodes)
     * and in Property.setValue (for properties to be modified).
