Constructor Details

PartitionHolder

public PartitionHolder(PartitionChunk<T> initialChunk)

PartitionHolder

public PartitionHolder(List<PartitionChunk<T>> initialChunks)

PartitionHolder

public PartitionHolder(PartitionHolderContents<T> contents,
 short maxMinorVersion)

Constructor for situations where the caller already has a PartitionHolderContents. Generally used for copying. Also used for tests.

Method Details

copyWithOnlyVisibleChunks

public static <T extends Overshadowable<T>>
PartitionHolder<T> copyWithOnlyVisibleChunks(PartitionHolder<T> partitionHolder)

deepCopy

public static <T extends Overshadowable<T>>
PartitionHolder<T> deepCopy(PartitionHolder<T> partitionHolder)

add

public boolean add(PartitionChunk<T> chunk)

getMaxMinorVersion

public short getMaxMinorVersion()

Returns the maximum minor version across all the added segments. We do not handle updates of this variable when segments are removed for the sake of simplicity.
