Package org.jfree.report.content Description

Report contents. Contents are abstract views of the data that should be printed in the OutputTarget. There are 3 known types of content yet: Text, Shapes and Images. The abstract view allows the logical page to format the content without knowing any details about the content itself.

Content may be split into several parts, so that portions of content for specific bounds can be extracted.

To create contents, an LayoutSupport defines a ContentFactory. This factory is resopnsible to create the content from the Element's value, if the OutputTarget does support the elements content type.

How content is created and used within the report processing

• The ContentFactory is used to create the content for the elements. The elements getValue() method is used to read the assigned content for the element. This raw data and the elements style definition is used to create the content. When using the DefaultContentFactory, the content is created using one of the defined ContentFactoryModules.
• The Content is then used to compute the size for the dynamic elements by the BandLayoutManager.
• PageableLayout: Once the layout is complete, the content is used in the logical page to create the required PhysicalOperations needed to display the content in the OutputTarget. This conversion is done by one of the OperationModules of the OutputTargets or LogicalPages OperationFactory.
• The generated PhysicalOperations are added to the physical page and finally printed when the physical page is closed.
