Defines the fundamental interfaces for those extensions from the
reportitem extension point.
Package Specification
The extension package defines the key interfaces of those extension implementation
from the reportitem extension point. All the implementation of reportitem extension
point build on these interfaces to offer the extension definition, extension properties,
extension choice, extension element, extension command and extension exception
and other concepts defined in the reportitem extension point schema.
The key interfaces in this package include:
- {@link org.eclipse.birt.report.model.api.extension.IReportItemFactory} provides methods to
access the meta data of an extended type of report element and create new instance of
the element{@link org.eclipse.birt.report.model.api.extension.IReportItem}. See the extensive
documentation in this interface for information about the services common to all
extension definition.
- {@link org.eclipse.birt.report.model.api.extension.IReportItem} Provides methods to
access/modify properties, these methods are to be implemented if the report item
stores its properties in its own model.
- {@link org.eclipse.birt.report.model.api.extension.IPropertyDefinition} and
{@link org.eclipse.birt.report.model.api.extension.IChoiceDefinition}
provide generic access to extension properties or extension structure members, and
choices for extension properties or members respectively.
- {@link org.eclipse.birt.report.model.api.extension.IElementCommand},
{@link org.eclipse.birt.report.model.api.extension.ExtendedElementException}integrate
with the models command stack, the extension plug-in needs to implement the
IElementCommand interface
