Method Detail

getSignature

public java.lang.String getSignature()

Description copied from interface: HistoricalData

The signature is a static string that describes this data as uniquely as possible. This will be used to group data in the data cache (for example, when displaying quarantined data), as well as uniquely identifying cacheable schemas, etc.

Basically, the golden rule is that if two pieces of data have the same signature, the came from the same place, and are going to the same place, and in theory could be grouped together (note: they won't be, that is done with the GroupableData interface).

Specified by:

getSignature in interface HistoricalData

getData

public java.util.List<HistoricalData> getData()

Specified by:

getData in interface DataTransaction

setData

public void setData(java.util.List<HistoricalData> data)

addData

public void addData(HistoricalData value)

getDataCount

public int getDataCount()

Description copied from interface: HistoricalData

This is a fairly ambiguous number, but basically indicates how many rows will ultimately be inserted in the database. Used for judging transaction size.

Specified by:

getDataCount in interface HistoricalData

getFlavor

public HistoryFlavor getFlavor()

Description copied from interface: HistoricalData

The very broad "flavor" designator, used to get the data to the correct sink. That is, different sinks support different types of data, and this is used to match them up.

Specified by:

getFlavor in interface HistoricalData

setFlavor

public void setFlavor(HistoryFlavor flavor)

getLoggerName

public java.lang.String getLoggerName()

Description copied from interface: HistoricalData

Returns the name of the logger that should be notified when something happens to this data. If null or empty, notifications won't occur (errors, however, may still be logged to the general logger).

Specified by:

getLoggerName in interface HistoricalData

setLoggerName

public void setLoggerName(java.lang.String logger)

isEmpty

public boolean isEmpty()

getGroupId

public java.lang.String getGroupId()

Description copied from interface: GroupableData

A string identifing the "group" of the data. In other words, any piece of data from this group can be merged together.

Specified by:

getGroupId in interface GroupableData

groupData

public GroupableData groupData(GroupableData other)

Description copied from interface: GroupableData

Merge another piece of similar data into this one.

Specified by:

groupData in interface GroupableData

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
