Example 1 with ValuesProperty

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

the class DefaultItemCollection method addMember.

/**
 * If the specified resource represents a collection, a new node is {@link Node#addNode(String)
 * added} to the item represented by this resource. If an input stream is specified
 * together with a collection resource {@link Session#importXML(String, java.io.InputStream, int)}
 * is called instead and this resource path is used as <code>parentAbsPath</code> argument.
 * <p>
 * However, if the specified resource is not of resource type collection a
 * new {@link Property} is set or an existing one is changed by modifying its
 * value.<br>
 * NOTE: with the current implementation it is not possible to create or
 * modify multivalue JCR properties.<br>
 * NOTE: if the JCR property represented by the specified resource has an
 * {@link PropertyType#UNDEFINED undefined} resource type, its value will be
 * changed/set to type {@link PropertyType#BINARY binary}.
