getFormVersion

public abstract java.lang.String getFormVersion()
                                         throws java.text.ParseException,
                                                java.io.IOException

Every File which is submitted to ETL have to be associated with the form version. This form version is either submitted from within the file or as one of the input to ETL . If Form Version submitted from within the file then we need to write the file parser in such a way so that it reads the from version . The FormVersion decides which version of map file should be used to transform the data.

Returns:

the version string

Throws:

java.text.ParseException

java.io.IOException

getData

public abstract java.util.Map<java.lang.String,Data> getData(java.io.File templateConfigFile)
                                                      throws org.apache.commons.configuration.ConfigurationException,

We need to parse the file and convert the data into #org.eaglei.datatools.etl.server.extractor.parsers.data . This method returns the Java.util.Map with 'key' as the name of Map file and 'value' as the Data.It needs template config file as input. This templateconfig will be having information about the file being extracted.

Parameters:

templateConfigFile -

Returns:

Throws:

org.apache.commons.configuration.ConfigurationException
