All Implemented Interfaces:

public class PropFindMethod
extends XMLResponseMethodBase
implements DepthSupport

This class implements the WebDAV PROPFIND Method.

The PROPFIND method retrieves properties defined on the resource identified by the Request-URI, if the resource does not have any internal members, or on the resource identified by the Request-URI and potentially its member resources, if the resource is a collection that has internal member URIs.

A typical request looks like this:


 PROPFIND /file HTTP/1.1
 Host: www.foo.bar
 Content-type: text/xml; charset="utf-8"
 Content-Length: xxxx

 <?xml version="1.0" encoding="utf-8" ?>
   <D:propfind xmlns:D="DAV:">
   <D:prop xmlns:R="http://www.foo.bar/boxschema/">
     <R:bigbox/>
     <R:author/>
     <R:DingALing/>
     <R:Random/>
   </D:prop>
 </D:propfind>

public void setRequestHeader(java.lang.String headerName,
                             java.lang.String headerValue)
Set a request header value, redirecting the special case of the "Depth" header to invoke setDepth(int) instead.

Specified by:
