Package net.sf.paperclips

Class BigPrint

java.lang.Object

net.sf.paperclips.BigPrint

All Implemented Interfaces:

Print

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

A wrapper for prints whose minimum size is too large to fit on one page. The target's content is divided across multiple pages like a spreadsheet. Pages are printed in order left-to-right, then top-to-bottom.

Note that this print lays out content under the assumption that every page will have the same pixel width and height. If a BigPrint is wrapped in a print that violates this expectation, it is likely that the output will skip and/or repeat certain portions of the target's content. Some examples of this behavior:

• BorderPrint changes the available page height of the target, depending on whether the top and bottom borders are open or closed.
• ColumnPrint often changes the width from column to column, if the total width is not evenly divisible by the number of columns.

Parameters:

target -

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 wrapped print which is being split across pages.

Returns:

the wrapped print which is being split across pages.

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.
