• Resource.getURI()

hashCode

public int hashCode()

This implementation returns a hashcode value composed from the reference URI, if available.

hashCode in class Object

toString

public static String toString(URI resourceURI)

Returns a reference string representation of the resource identified by the given URI. This version returns the URI between double angle quotation marks.

Parameters:

resourceURI - The resource URI for which a reference string should be returned.

Returns:

A reference string representation of the resource.

Throws:

NullPointerException - if the given resource URI is null.

toString

public static String toString(Resource resource)

Returns a reference string representation of the given resource. This version returns the URI, if there is one, between double angle quotation marks; otherwise, an ID using the resource's hash code is used.

Parameters:

resource - The resource for which a reference string should be returned.

Returns:

A reference string representation of the resource.

public 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 Object
