protected void assignProperties(ExporterContext context,
                                java.lang.Object primaryObject)
                         throws java.lang.Exception

Throws:

public void exportInto(ExporterContext context,
                       Block rootBlock,
                       java.lang.Object primaryObject)
                throws java.lang.Exception

Description copied from interface: BlockExporter

Export an object into a supplied Block instance. This is effectively the "lowest" level interface to exporting.

Specified by:

exportInto in interface BlockExporter

Parameters:

context - The ExporterContext object.

rootBlock - The root Block to export INTO.

primaryObject - The primary object that we are export.

Throws:

java.lang.Exception - If we are unable to create a Block instance.

exportBlock

public Block exportBlock(ExporterContext context,
                         java.lang.String blockName,
                         java.lang.Object primaryObject)
                  throws java.lang.Exception

Description copied from interface: BlockExporter

Instead of exporting INTO a Block, this method exports a Block. It is up to the caller to determine what is done with it. This method creates a Block and then calls BlockExporter.exportInto(ExporterContext, Block, Object).

Specified by:

exportBlock in interface BlockExporter

Parameters:

context - The ExporterContext object.

blockName - The name of the root block to create an instance for.

primaryObject - The primary object that we are export.

Returns:

The Block created by the Exporter.

Throws:

java.lang.Exception - If we are unable to create a Block instance.

exportList

public BlockList exportList(ExporterContext context,
                            java.lang.Object primaryObject)
                     throws java.lang.Exception

Description copied from interface: BlockExporter

Instead of exporting into a supplied BlockList, this method simply creates a new, empty BlockList and then calls BlockExporter.exportInto(ExporterContext, BlockList, Object). The newly created BlockList is returned.

Specified by:

exportList in interface BlockExporter

Parameters:

context - The ExporterContext object.

primaryObject - The primary object that we are export.

Returns:

The BlockList created by the Exporter.

Throws:

java.lang.Exception - If we are unable to create a Block instance.

exportBlock

public Block exportBlock(ExporterContext context,
                         java.lang.Object primaryObject)
                  throws java.lang.Exception

Description copied from interface: BlockExporter

Instead of exporting INTO a named Bloc, this exports into a Block defined by the Exporter class. This method collects the root block defined by Exporter and calls BlockExporter.exportBlock(ExporterContext, String, Object).

Specified by:

exportBlock in interface BlockExporter

Parameters:

context - The ExporterContext object.

primaryObject - The primary object that we are export.

Returns:

The Block created by the Exporter.

Throws:

java.lang.Exception - If we are unable to create a Block instance.

exportInto

public void exportInto(ExporterContext context,
                       BlockList blockList,
                       java.lang.Object primaryObject)
                throws java.lang.Exception

Description copied from interface: BlockExporter

Instead of exporting into a BLOCK, this method exports the generated Block into the supplied LIST.

Specified by:

exportInto in interface BlockExporter

Parameters:

context - The ExporterContext object.

blockList - The BlockList to export INTO.

primaryObject - The primary object that we are export.

Throws:

java.lang.Exception - If we are unable to create a Block instance.
