Class SimpleDoc

public final class SimpleDoc extends Object implements Doc

Simple implementation of the 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.

Constructor Summary
	SimpleDoc(Object printData, DocFlavor flavor, DocAttributeSet attributes) Constructs a SimpleDoc with the specified print data, doc flavor and doc attribute set.

Method Summary
DocAttributeSet	getAttributes() Returns the unmodifiable view of the attributes of this doc object.
DocFlavor	getDocFlavor() Returns the flavor of this doc objects print data.
Object	getPrintData() Returns the print data of this doc object.
Reader	getReaderForText() Returns a `Reader` object for extracting character print data from this document.
InputStream	getStreamForBytes() Returns an `InputStream` object for extracting byte print data from this document.

Constructor Detail

SimpleDoc

public SimpleDoc(Object printData, DocFlavor flavor, DocAttributeSet attributes)

Constructs a SimpleDoc with the specified print data, doc flavor and doc attribute set.

Parameters: 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).

Throws: 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.

Method Detail

getAttributes

public DocAttributeSet getAttributes()

Returns the unmodifiable view of the attributes of this doc object.

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.

Returns: The unmodifiable attributes set, or null.

getDocFlavor

public DocFlavor getDocFlavor()

Returns the flavor of this doc objects print data.

Returns: The document flavor.

getPrintData

public Object getPrintData()

Returns the print data of this doc object.

The returned object is an instance as described by the associated document flavor ({@link DocFlavor#getRepresentationClassName()}) and can be cast to this representation class.

Returns: The print data in the representation class.

Throws: IOException if representation class is a stream and I/O exception occures.

getReaderForText

public Reader getReaderForText()

Returns a Reader object for extracting character print data from this document.

This method is supported if the document flavor is of type:

char[]
java.lang.String
java.io.Reader

otherwise this method returns null.

Returns: The Reader object, or null.

Throws: IOException if an error occurs.

getStreamForBytes

public InputStream getStreamForBytes()

Returns an InputStream object for extracting byte print data from this document.

This method is supported if the document flavor is of type:

byte[]
java.io.InputStream

otherwise this method returns null.

Returns: The InputStream object, or null.

Throws: IOException if an error occurs.
