Resource

All Known Implementing Classes:

BinaryResource, FailedResource, JSONResource, MetadataResource, UnknownResource, UnparsedTextResource, XmlResource
```
public interface Resource
```
This interface defines a Resource. The Resource objects belong to a collection. It is used to support the fn:collection() and fn:uri-collection() functions.
It is recommended (but is not universally the case) that fetching (and where necessary parsing) the content of a Resource should be delayed until the getItem(net.sf.saxon.expr.XPathContext) method is called. This means that errors in fetching the resource or parsing its contents may go undetected until the resource is materialized in this way.

- Method Detail
  - getResourceURI
```
java.lang.String getResourceURI()
```
    Get a URI that identifies this resource
    
    Returns:
    
    a URI identifying this resource
  - getItem
```
Item getItem(XPathContext context)
      throws XPathException
```
    Get an XDM Item holding the contents of this resource.
    
    Parameters:
    
    context - the XPath evaluation context
    
    Returns:
    
    an item holding the contents of the resource. The type of item will reflect the type of the resource: a document node for XML resources, a string for text resources, a map or array for JSON resources, a base64Binary value for binary resource. May also return null if the resource cannot be materialized and this is not to be treated as an error.
    
    Throws:
    
    XPathException - if a failure occurs materializing the resource
  - getContentType
```
java.lang.String getContentType()
```
    Get the media type (MIME type) of the resource if known
    
    Returns:
