Constructor Detail

AccountingUpdater

public AccountingUpdater(uk.ac.ed.epcc.webapp.AppContext conn,
                 PropertyMap meta_data,
                 UsageRecordParseTarget<T> t)

Create an AccountingUpdater. This sets the ParseTarget class used to parse the records and a set of MetaData properties. These are properties that come from the surrounding code (such as the person performing the upload or the machine the data is from if this is not included in the individual records). MetaProperties must be the same for every record parsed in this pass but data from a different upload may have different values.

Parameters:

conn - AppContext

meta_data - MetaData properties

t - ParseTarget
