Method Detail

parse

public boolean parse(PropertyMap map,
            java.lang.String record)
              throws AccountingParseException

Description copied from interface: PropertyContainerParser

Parse a String representation of the UsageRecord. If the parse needs to be aborted throw and AccountingParseException. If the parse cannot succeed but no error needs to be reported (e.g. an empty or comment line) this method can return false

Specified by:

parse in interface PropertyContainerParser

Throws:

AccountingParseException

Parameters:

map - PropertyMap to add quantities

Returns:

true if parse ok

initFinder

public PropertyFinder initFinder(uk.ac.ed.epcc.webapp.AppContext ctx,
                        PropertyFinder prev,
                        java.lang.String table)

Description copied from interface: PropertyContainerUpdater

Generate a PropertyFinder that will find any PropertyTag generated by this class. This call should be treated as a secondary constructor and should be called before any other method from this interface.

All properties defined at run-time should have their PropertyTag objects constructed by the time the first call to this method returns. As some parsers properties will generate different things depending on the other properties already in scope this method is passed a PropertyFinder for any properties that may already be in scope. This will include any default parameters specified when the data was uploaded and any properties generated from the database meta-data. Though it is perfectly legal to return a PropertyFinder that returns a superset of the generated properties the only requirement is that the returned finder can find any property that this classes parse method may actually generate values for. So Normally the contents of the super-finder are not included in the result unless these values are actually generated by the parse. If values are generated then a MultiFinder can be populated with the PropertyRegistrys from the generated properties

Specified by:

initFinder in interface PropertyContainerUpdater

prev - PropertyFinder for the higher levels in the call chain.

table - String name of the destination table in case per-table customisation is needed

Returns:

PropertyFinder or null

getDefaultUniqueProperties

public java.util.Set<PropertyTag> getDefaultUniqueProperties()

Description copied from interface: PropertyContainerParser

Get the default set of unique properties for this parser

Specified by:

getDefaultUniqueProperties in interface PropertyContainerParser

Overrides:

getDefaultUniqueProperties in class AbstractPropertyContainerParser

Returns:

Set of PropertyTag or null
