public final class SimpleDoc extends Object implements Doc
Doc
interface capable of handling
the predefined document flavors of DocFlavor
.
This implementation can construct a reader or stream for the service from the print data and ensures that always the same object is returned on each method call. It does simple checks that the supplied data matches the specified flavor of the doc object and supports thread safe access.

public SimpleDoc(Object printData, DocFlavor flavor, DocAttributeSet attributes)
printData
- the object with the data to print.flavor
- the document flavor of the print data.attributes
- the attributes of the doc (may be null
).IllegalArgumentException
- if either printData
or
flavor
are null
, or the print data is not
supplied in the document format specified by the given flavor object.public DocAttributeSet getAttributes()
The attributes of this doc's attributes set overrides attributes of
the same category in the print job's attribute set. If an attribute
is not available in this doc's attributes set or null
is returned the attributes of the same category of the print job are
used.
