Example 1 with NamespacesProperty

use of org.apache.jackrabbit.webdav.jcr.property.NamespacesProperty in project jackrabbit by apache.

the class WorkspaceResourceImpl method setProperty.

/**
     * Allows to alter the registered namespaces ({@link ItemResourceConstants#JCR_NAMESPACES})
     * or register node types {@link ItemResourceConstants#JCR_NODETYPES_CND}
     * where the passed value is a cnd string containing the definition
     * and forwards any other property to the super class.
     * <p>
     * Note that again no property status is set. Any failure while setting
     * a property results in an exception (violating RFC 2518).
     *
     * @param property
     * @throws DavException
     * @see DavResource#setProperty(org.apache.jackrabbit.webdav.property.DavProperty)
