Called by the MapEngine when a new instance that requires this data source is going to be created. Can be used to open connections to data sources. Be careful when processing the inputs because the same mapper could use more than one driver and inputs are shared across all the drivers. Don't assume there will always be just one driver providing data to the mapper.

Specified by:

public void startOfFact(java.lang.String mapIdentifier,
               javax.xml.namespace.QName factName)

Description copied from interface: XBRLDataSource

Called by the MapEngine when a new fact is about to be started Return nothing. It is used to inform the "other side" and can be used to attach resources

Specified by:

startOfFact in interface XBRLDataSource

Parameters:

factName - QName

endOfFact

public void endOfFact(java.lang.String mapIdentifier,
             javax.xml.namespace.QName factName)

Specified by:

endOfFact in interface XBRLDataSource

Parameters:

mapIdentifier - the map identifier

factName - the fact name

isInputFileRequired

public boolean isInputFileRequired()

Description copied from interface: XBRLDataSource

Returns true if this driver requires an input file. This function is used by the GUI in order to enable or disable the "Test Mapper" menu item depending on whether or not input files are required

Specified by:

isInputFileRequired in interface XBRLDataSource

Returns:

boolean

isTupleSourceRequired

public boolean isTupleSourceRequired()

Description copied from interface: XBRLDataSource

Returns a boolean value indicating if the source format has a meaning to indicate the number of occurrences of a tuple.

This information is used during the algorithm for generating a template file automatically.

Excel Data Source, for example, does not provides a meaning to indicate the number of occurrences of a tuple. The number of occurrences will be indicated in the instance document template itself. SQL Data Source, is on the other side. The SQL Driver and the source format may have information to provide the number of occurrences for a tuple.

Note, once a template has been automatically generated. it is up to the team to change the generated template into something different if this is required by the project.

Specified by:

isTupleSourceRequired in interface XBRLDataSource

Returns:

boolean value.

getSourceReference

Specified by:

getSourceReference in interface XBRLDataSource

Parameters:

mapIdentifier - current map identifier

index - current index for the map identifier

String with target description

verifyRule

public boolean verifyRule(Section section)

Description copied from interface: XBRLDataSource

Checks the current driver for a rule for section passed in in the parameter. If the rule is satisfied the return value shall be true, otherwise, the return value shall be false.

This method is called only if the fact contains a sectionRef and the sectionRef contains a rule.

The algorithm to determine the output value is driver dependant and there is no default value.
