SparkDataItemPersistor

An object that can persist data to the database.

By default, the persistor will perform a selective update based on the changed data, without checking the version

persist

signature persist()

Persists the state of the document to the database using the supplied strategies.

This method will return false if either the conditional check, or the version check fail

signature withAtomicIncrements()

If set, only the changes that have been made to this document are persisted.

Additionally, any numeric changes will be atomically incremented or decremented based on the original value

This method will turn off 'withOverwrite' if it's been previously specified

signature withConditionCheck(SparkDataCondition condition)

If supplied, the conditions will be used to do a conditional update

signature withErrorOnTypeConversion()

If set, when the document is serialized for persistance, if an unsupported data type is found, an exception will be thrown

signature withOverwrite()

If set, all fields in the document are persisted, even if they have not been changed, potentially overwriting changes made by other updates.

This method will turn off 'withAtomicIncrements' if it's been previously specified.

signature withVersionCheck()

If set, the document's version number will be used to do a conditional update.

If the version number in the DB is different to the version number in this instance, the persist call will return false
