Method Detail

getDeltaBaseCacheLimit

public int getDeltaBaseCacheLimit()

Get maximum number of bytes to hold in per-reader DeltaBaseCache.

Returns:

maximum number of bytes to hold in per-reader DeltaBaseCache.

setDeltaBaseCacheLimit

public DfsReaderOptions setDeltaBaseCacheLimit(int maxBytes)

Set the maximum number of bytes in the DeltaBaseCache.

Parameters:

maxBytes - the new limit.

Returns:

this

getStreamFileThreshold

public int getStreamFileThreshold()

Get the size threshold beyond which objects must be streamed.

Returns:

the size threshold beyond which objects must be streamed.

setStreamFileThreshold

public DfsReaderOptions setStreamFileThreshold(int newLimit)

Set new byte limit for objects that must be streamed.

Parameters:

newLimit - new byte limit for objects that must be streamed. Objects smaller than this size can be obtained as a contiguous byte array, while objects bigger than this size require using an ObjectStream.

Returns:

this

getStreamPackBufferSize

public int getStreamPackBufferSize()

Get number of bytes to use for buffering when streaming a pack file during copying.

Returns:

number of bytes to use for buffering when streaming a pack file during copying. If 0 the block size of the pack is used.

setStreamPackBufferSize

public DfsReaderOptions setStreamPackBufferSize(int bufsz)

Set new buffer size in bytes for buffers used when streaming pack files during copying.

Parameters:

bufsz - new buffer size in bytes for buffers used when streaming pack files during copying.

Returns:

this

fromConfig

public DfsReaderOptions fromConfig(Config rc)

Update properties by setting fields from the configuration.

If a property is not defined in the configuration, then it is left unmodified.

Parameters:

rc - configuration to read properties from.

Returns:

this
