Enum Class ALfnTileStore.CommitPolicy

java.lang.Object

java.lang.Enum<ALfnTileStore.CommitPolicy>

com.luciad.fusion.tilestore.ALfnTileStore.CommitPolicy

All Implemented Interfaces:

Serializable, Comparable<ALfnTileStore.CommitPolicy>, Constable

Enclosing class:

ALfnTileStore

public static enum ALfnTileStore.CommitPolicy
extends Enum<ALfnTileStore.CommitPolicy>

The commit policy determines when new tiles will be visible.

• PER_TILE means that new tiles will be visible immediately. This is the default. As fusion progresses, new tiles will become visible incrementally. However, it also means that a view consisting of multiple tiles may be inconsistent: some tiles may be new, others may be old (or missing).
• PER_COVERAGE means that new tiles will not be visible until fusion completes. After completion, new tiles become visible all at once. The completion of fusion is triggered by an put of the coverage metadata, when all its assets become complete. This policy does not work well with the fusion engine's checkpointing mechanism.
  • When used in combination with checkpointing, all engine sessions must be configured to produce all levels. This can be done by calling setLevelsToProduce on a RasterSessionBuilder with an array containing all levels, such as new byte[] { 0, 1, ..., 24 } . Note that this may introduce scalability issues when there are lots (hundreds) of new assets to be fused in that session.
  • Alternatively, the saving of checkpoints can be disabled by setting the checkpoint directory to null on the ALfnEngineEnvironment.
