public class ImagePermission extends Permission
Image
. Permission is checked when calling one of the following methods:Image.canGetImage(String)
,Image.getImage(String)
,ResourceImage.canLoadImage(String)
,ResourceImage.loadImage(String)
,ResourceImage.loadImage(String, ResourceImage.OutputFormat)
,ResourceImage.loadImage(InputStream, int)

method.

public int hashCode()
Permission
The required hashCode
behavior for Permission Objects is the following:
hashCode
method must consistently return the same integer.
This integer need not remain consistent from one execution of an application to another execution
of the same application.
equals
method, then calling
the hashCode
method on each of the two Permission objects must produce the same
integer result.

public boolean implies(Permission permission)
Permission
This must be implemented by subclasses of Permission, as they are the only ones that can impose semantics on a Permission object.
