Field Detail

trustEntityTimestamp

protected boolean trustEntityTimestamp

If the entity has an update timestamp/date then should we trust that or assign the time of tracking when this code is called. In mission critical applications the date/time when the update occoured can be important.

Also because a TrackTransformer can be called asynchronously, the Date/Time when it was called Vs when the change actually occured can be important.

Default value:

false

curDateTime

protected transient Date curDateTime

TrackTransformer

public TrackTransformer()

actionOnTrack

protected Consumer<TR> actionOnTrack()

Define a Custom action on track object

Consumer of Track type

transform

public Object transform(Object input)

Specified by:

transform in interface org.apache.commons.collections.Transformer

track

protected abstract TR track(E e)

Convert Entity to Trackable Object

Parameters:

e - as Entity type

Returns:

Track

isTrustEntityTimestamp

public boolean isTrustEntityTimestamp()
