Interface XBRLLoaderInterface

All Known Implementing Classes:

ExcelReportFactHandler, NullDriver, SQLDriver

public interface XBRLLoaderInterface

This is the interface for drivers responsible of handling events about data loading in repositories like excel files, databases or any other formats. The driver knows how to work with the target environment. Each driver may have a configuration file. Data loading events are generated by the loader engine and they are independent of the driver to use. XBRL data can be targeted to more that one driver.

Method Summary

XBRLTransformationResult	createNewResult(net.sf.saxon.s9api.Processor configuration) Creates a new document container.
void	endOfDocument() Called by the transformation processor to indicate the end of a document processing Usually a document footer is produced.
java.net.URI	getConfigFile() Returns back the URI of the configuration file
void	init() This method is called by the loader just after object has been created and if a configuration file is set (which is an optional step only if configuration file is indicated as a parameter) This method should read the configuration file and set values for constants and things like that.
void	processContexts(java.util.Iterator<XBRLContext> contexts) Called by the transformation processor to provide the contexts for the data that will be found later during the processing of facts the default process updates the content of some variables. or calculates number of columns, rows.
void	processFact(java.lang.String identifier, XBRLFact fact) Called by the processor to inform about a new fact that requires processing.
void	setConfigFile(java.net.URI configFile) This method is called by the loader when a new loader is just created and for each one of the drivers that exist on the loader configuration file and only if the driver has a parameter indicating the URL of the configuration file Next call is init()
void	startOfDocument(XBRLInstance instance) Called by the transformation processor to indicate the start of a new document.

Method Detail

setConfigFile

void setConfigFile(java.net.URI configFile)

This method is called by the loader when a new loader is just created and for each one of the drivers that exist on the loader configuration file and only if the driver has a parameter indicating the URL of the configuration file Next call is init()

Parameters:

configFile -

init

void init()
          throws LoaderConfigurationFileException

This method is called by the loader just after object has been created and if a configuration file is set (which is an optional step only if configuration file is indicated as a parameter) This method should read the configuration file and set values for constants and things like that. Next call is createNewResult(Processor)

Throws:

LoaderConfigurationFileException

createNewResult

XBRLTransformationResult createNewResult(net.sf.saxon.s9api.Processor configuration)
                                         throws FactHandlerException

Creates a new document container. This method is the first one called when a new instance document requires to be processed. This method can be used to open connections to the target repository. Next call is startOfDocument(XBRLInstance)

Parameters:

configuration - Saxon s9api Processor object

Returns:

XBRLTransformationResult an object that implements the XBRLTransformationResult interface.

Throws:

FactHandlerException - if anything goes wrong.

startOfDocument

void startOfDocument(XBRLInstance instance)
                     throws FactHandlerException

Called by the transformation processor to indicate the start of a new document. Usually a document header is produced. A new template document is initialized or a transaction is created. Next call is processContexts(Iterator)

Parameters:

instance -

Throws:

FactHandlerException

processContexts

void processContexts(java.util.Iterator<XBRLContext> contexts)

Called by the transformation processor to provide the contexts for the data that will be found later during the processing of facts the default process updates the content of some variables. or calculates number of columns, rows. Next call is processFact(String, XBRLFact) for facts that passes the filters established by the loader engine and are the true loading events.

Parameters:

contexts - Iterator<XBRLContext>

processFact

void processFact(java.lang.String identifier,
                 XBRLFact fact)
                 throws FactHandlerException

Called by the processor to inform about a new fact that requires processing. This is where the real loading event is handled by the driver. Next call is endOfDocument() when the instance document is finished and no more events needs to be generated

Parameters:

identifier - as String which is the identifier code in the loader configuration file.

fact - XBRLFact the loaded fact

Throws:

FactHandlerException - if something goes wrong.

endOfDocument

void endOfDocument()
                   throws FactHandlerException

Called by the transformation processor to indicate the end of a document processing Usually a document footer is produced. Or the transaction is committed. There is no a next call.

Throws:

FactHandlerException - if something goes wrong

getConfigFile

java.net.URI getConfigFile()

Returns back the URI of the configuration file

Returns:

URI
