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>

setRequestHeader

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:

setRequestHeader in interface org.apache.commons.httpclient.HttpMethod

Overrides:

setRequestHeader in class org.apache.commons.httpclient.HttpMethodBase

Parameters:

headerName - Header name

headerValue - Header value

setType

public void setType(int type)

Type setter.

Parameters:

type - New type value

getType

public int getType()

Type getter.

Returns:

int type value

setDepth

public void setDepth(int depth)

Depth setter.

Specified by:

Depth getter.

Specified by:

getDepth in interface DepthSupport

Returns:

int depth value

setPropertyNames

public void setPropertyNames(java.util.Enumeration propertyNames)

Property names setter. The enumeration may contain strings with or without a namespace prefix but the preferred way is to provide PropertyName objects.

Parameters:

recycle

public void recycle()

Description copied from class: XMLResponseMethodBase

Reset the State of the class to its initial state, so that it can be used again.

Specified by:
