All Implemented Interfaces:

PropertyBindable, PropertyConstrainable, Resource, java.lang.Comparable<Resource>

public class BoundPropertyResource
extends BoundPropertyObject
implements Resource, java.lang.Comparable<Resource>

Represents the default implementation of a resource that recognizes bound properties. This class provides compare functionality that sorts according to the reference URI, if available.

Constructor Detail

BoundPropertyResource

protected BoundPropertyResource()

Default constructor that allows the reference URI to be set later.

BoundPropertyResource

protected BoundPropertyResource(java.net.URI referenceURI)

Constructs a resource with a reference URI.

Parameters:

referenceURI - The reference URI for the new resource.

Method Detail

getURI

public java.net.URI getURI()

Specified by:

getURI in interface Resource

Returns:

The resource identifier URI, or null if the identifier is not known.

setReferenceURI

public void setReferenceURI(java.net.URI uri)

Sets the reference URI of the resource.

Parameters:

uri - The new reference URI, or null if the identifier is not known.

equals

public boolean equals(java.lang.Object object)

Compares the resource reference URIs. If neither object has a reference URI, the default identity comparison is performed.

Overrides:

equals in class java.lang.Object

Parameters:

object - The object with which to compare this resource.

Returns:

true if this resource equals that specified in object.

See Also:

getURI(), AbstractResource.equals(Object)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

A hashcode value composed from the reference URI, if available.

compareTo

public int compareTo(Resource resource)

Compares this object to another object.

This method determines order based upon the reference URI of the resource, if any; otherwise, the hash codes of the resources are compared. The resource with no URI is sorted before a resource with a URI. The same resource will always be considered equal.

Specified by:

compareTo in interface java.lang.Comparable<Resource>

Parameters:

resource - The resource with which to compare this resouce.

Returns:

A negative integer, zero, or a positive integer as this resource reference URI is less than, equal to, or greater than the reference URI of the specified resource, respectively.

See Also:

getURI(), hashCode(), DefaultResource.compareTo(Resource)

toString

public java.lang.String toString()

Returns a string representation of the resource. This version returns the URI, if there is one, between double angle quotation marks; otherwise the default string representation of the object is returned.

Overrides:

toString in class java.lang.Object

Returns:

A string representation of the resource.
