Method Details

newDefaultsForObjects

public static AdvancedRangeCacheConfigImpl newDefaultsForObjects()

PageSize : 100000 objects MaxRequestsize : unlimited Sync delay : 5 seconds Internal buffer size: 1024 objects Values subject to change.

Returns:

newDefaultsForObjects

public static AdvancedRangeCacheConfigImpl newDefaultsForObjects(long requestSize)

newDefaultForBytes

public static AdvancedRangeCacheConfigImpl newDefaultForBytes()

PageSize : 16MB MaxRequestsize : unlimited Sync delay : 5 seconds Internal buffer size: 8KB Values subject to change.

Returns:

newDefaultForBytes

public static AdvancedRangeCacheConfigImpl newDefaultForBytes(long requestSize)

getPageSize

public int getPageSize()

Specified by:

getPageSize in interface AdvancedRangeCacheConfig

setPageSize

public AdvancedRangeCacheConfigImpl setPageSize(int pageSize)

getMaxRequestSize

public long getMaxRequestSize()

Specified by:

getMaxRequestSize in interface AdvancedRangeCacheConfig

setMaxRequestSize

public AdvancedRangeCacheConfigImpl setMaxRequestSize(long maxRequestSize)

getTerminationDelay

public Duration getTerminationDelay()

Specified by:

getTerminationDelay in interface AdvancedRangeCacheConfig

setTerminationDelay

public AdvancedRangeCacheConfigImpl setTerminationDelay(Duration terminationDelay)

getInternalWorkerSize

public int getInternalWorkerSize()

Specified by:

getInternalWorkerSize in interface AdvancedRangeCacheConfig

setInternalWorkerSize

public void setInternalWorkerSize(int internalWorkerSize)

getReadBeforeSize

public long getReadBeforeSize()

Specified by:

getReadBeforeSize in interface AdvancedRangeCacheConfig

Returns:

setReadBeforeSize

public void setReadBeforeSize(long readBeforeSize)

getMaxReadAheadItemCount

public int getMaxReadAheadItemCount()

Description copied from interface: AdvancedRangeCacheConfig

How far a channel may by default read ahead.

Specified by:

getMaxReadAheadItemCount in interface AdvancedRangeCacheConfig

setMaxReadAheadItemCount

public void setMaxReadAheadItemCount(int maxReadAheadItemCount)

hashCode
