Class SidewaysPrint

java.lang.Object
  net.sf.paperclips.SidewaysPrint

All Implemented Interfaces:

Print

public final class SidewaysPrint
extends java.lang.Object
implements Print

A decorator print that rotates it's target by increments of 90 degrees.

Note: On Windows, this class depends on a bugfix available as of Eclipse build 3.2, release candidate 3 (2006-04-28). Prior to this release, using SidewaysPrint triggers the bug, causing the document to scale very large on paper. This bug only manifests itself on paper, not with on-screen viewing.

SidewaysPrint, unlike RotatePrint, is neither horizontally nor vertically greedy. Greedy prints take up all the available space on the page.

Constructor Summary

SidewaysPrint(Print target)
Constructs a SidewaysPrint that rotates it's target 90 degrees counter-clockwise.

SidewaysPrint(Print target, int angle)
Constructs a SidewaysPrint.

Method Summary

boolean	equals(java.lang.Object obj)
int	getAngle() Returns the angle by which the target will be rotated (one of 0, 90, 180, or 270).
Print	getTarget() Returns the print to be rotated.
int	hashCode()
PrintIterator	iterator(org.eclipse.swt.graphics.Device device, org.eclipse.swt.graphics.GC gc) Returns a PrintIterator for laying out the contents of this Print.

Constructor Detail

SidewaysPrint

public SidewaysPrint(Print target)

Constructs a SidewaysPrint that rotates it's target 90 degrees counter-clockwise.

Parameters:

target - the print to rotate.

SidewaysPrint

public SidewaysPrint(Print target,
                     int angle)

Constructs a SidewaysPrint.

Parameters:

target - the print to rotate.

angle - the angle by which the target will be rotated, expressed in degrees counter-clockwise. Positive values rotate counter-clockwise, and negative values rotate clockwise. Must be a multiple of 90.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getTarget

public Print getTarget()

Returns the print to be rotated.

Returns:

the print to be rotated.

getAngle

public int getAngle()

Returns the angle by which the target will be rotated (one of 0, 90, 180, or 270).

Returns:

the angle by which the target will be rotated.

iterator

public PrintIterator iterator(org.eclipse.swt.graphics.Device device,
                              org.eclipse.swt.graphics.GC gc)

Description copied from interface: Print

Returns a PrintIterator for laying out the contents of this Print. The iterator uses a snapshot of the print at the time this method is invoked, so subsequent changes to the Print will not affect the output of the iterator.

Specified by:

iterator in interface Print

Parameters:

device - the graphics device this Print will be drawn onto.

gc - the graphics context to be used for calculating layout and drawing the Print's contents.

Returns:

a PrintIterator for laying out the contents of this Print.
