Field Summary

Fields
Modifier and Type	Field and Description
`static WriteModifiers`	`MEMORY_ONLY_SEARCH` Look only in memory for existence of entry with the same ID - do not use the underlying external data source.
`static WriteModifiers`	`NONE` Empty - use operation default behavior.
`static WriteModifiers`	`ONE_WAY` Operation is executed in one way mode, meaning no return value will be provided.
`static WriteModifiers`	`PARTIAL_UPDATE` Update only non-null properties, ignore null properties.
`static WriteModifiers`	`RETURN_PREV_ON_UPDATE` If the entry already exists in the space, return the old entry in the result.
`static WriteModifiers`	`UPDATE_ONLY` If the entry does not exists in the space throw an EntryNotInSpaceException.
`static WriteModifiers`	`UPDATE_OR_WRITE` If the entry does not exists in the space it is written, otherwise it is updated.
`static WriteModifiers`	`WRITE_ONLY` If the entry already exists in the space throw an EntryAlreadyInSpaceException.

    Operation is executed in one way mode, meaning no return value will be provided. Using this mode provides no guarantee whether the operation succeeded or not, the only guarantee is that the operation was successfully written to the local network buffer. As a result, using this modifier will cause the operation not to guarantee automatic fail-over if the primary space instance failed, and it cannot be done under a transaction. When used with an auto generated id space entry, the local entry instance will not be updated with the generated id as this is done on the server. The same applies for version property.
  - MEMORY_ONLY_SEARCH
```
public static final WriteModifiers MEMORY_ONLY_SEARCH
```
    Look only in memory for existence of entry with the same ID - do not use the underlying external data source. We assume that if an entry with the same ID does not reside in cache - it does not exist in the underlying external data source either. When using this modifier special care should be taken into consideration, it is the responsibility of the caller when using this modifier to make sure the entry does not reside in the external data source, failing to do so may cause inconsistent and fatal behavior of the system at a later point when this entry is trying to be persisted into the external data source but it already exists there.
