* The class contains all report properties and report elements inherited from the
* {@link net.sf.jasperreports.engine.JRReport} interface
* in their design time state.
*
* All its instances are subject to compilation before being used for filling and report
* generation. These instances are the raw material that the JasperReports library uses to generate
* reports. Such instances are usually obtained:
*
* - by parsing the JRXML report template files
* using the library's internal XML-parsing utility classes.
* - by applications that use JasperReports through API calls if
* working with JRXML files is not an option.
*
*
* The first option for creating report designs relies on editing the JRXML files and using them
* with the {@link net.sf.jasperreports.engine.JasperCompileManager} in order to prepare them
* for filling with data. Because they are well structured and are validated against a public
* XSD when parsed, these files can be easily edited using simple editors or specialized
* XML editors.
*
* The second option is recommended only in case the parent application that uses
* JasperReports inside the reporting module needs to create report templates at runtime. In
* most cases this is not needed because the report templates do not need to change with
* every report execution, and hence static report templates could be used. Only the data
* used to fill these static report templates is dynamic.
*
* However, there are cases when the actual report template is the result of some user input.
* The parent application might supply its users with a set of options when launching the
* reports that might take the form of some simplified report designer or wizard. In such
* cases, the actual report layout is not known or is not complete at design time, and can
* only be put together after the user's input is received.
*
* The most common use case scenario that requires dynamically built or ad hoc report
* templates (as we call them) is one in which the columns that are going to be present in a
* table-like report layout are not known at design time. Instead, the user will give the
* number of columns and their order inside the desired report at runtime.
*
* Developers have to make sure that the applications they create really need ad hoc reports
* and cannot rely solely on static report templates. Since dynamically built report
* templates have to be compiled on the fly at runtime, they can result in a certain loss of
* performance.
