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()
returns SparkDataResult
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
withAtomicIncrements
signature withAtomicIncrements()
returns SparkDataItemPersistor
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
withConditionCheck
signature withConditionCheck(SparkDataCondition condition)
returns SparkDataItemPersistor
If supplied, the conditions will be used to do a conditional update
withErrorOnTypeConversion
signature withErrorOnTypeConversion()
returns SparkDataItemPersistor
If set, when the document is serialized for persistance, if an unsupported data type is found, an exception will be thrown
withOverwrite
signature withOverwrite()
returns SparkDataItemPersistor
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.
withVersionCheck
signature withVersionCheck()
returns SparkDataItemPersistor
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
