Interface DiskWriteAttributes

All Superinterfaces:

Serializable

Deprecated.

as of 6.5 use DiskStore instead

@Deprecated
public interface DiskWriteAttributes
extends Serializable

Immutable parameter object for describing how region entries should be written to disk.

Since:

GemFire 3.2

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object o) Deprecated. Two DiskWriteAttributes are equal if the both specify the synchronous writes, or they both specify asynchronous writes with the same time interval, bytes threshold, maxOplogSize and compaction values
long	getBytesThreshold() Deprecated. as of 6.5 use DiskStore.getQueueSize() instead.
int	getMaxOplogSize() Deprecated. as of 6.5 use DiskStore.getMaxOplogSize() instead.
long	getTimeInterval() Deprecated. as of 6.5 use DiskStore.getTimeInterval() instead.
boolean	isRollOplogs() Deprecated. Returns true if the oplogs is to be rolled to a more condensed format (on disk)
boolean	isSynchronous() Deprecated. as of 6.5 use RegionAttributes.isDiskSynchronous() instead.

Method Detail

isSynchronous

@Deprecated
boolean isSynchronous()

Deprecated. as of 6.5 use RegionAttributes.isDiskSynchronous() instead.

Returns true if this DiskWriteAttributes object configures synchronous writes.

Returns:

Returns true if writes to disk are synchronous and false otherwise

isRollOplogs

boolean isRollOplogs()

Deprecated.

Returns true if the oplogs is to be rolled to a more condensed format (on disk)

Returns:

Returns true if the oplogs is to be rolled or false otherwise

getMaxOplogSize

@Deprecated
int getMaxOplogSize()

Deprecated. as of 6.5 use DiskStore.getMaxOplogSize() instead.

Get the maximum size in megabytes a single oplog (operation log) file should be

Returns:

the maximum size the operations log file can be

getTimeInterval

@Deprecated
long getTimeInterval()

Deprecated. as of 6.5 use DiskStore.getTimeInterval() instead.

Returns the number of milliseconds that can elapse before unwritten data is written to disk. If this DiskWriteAttributes configures synchronous writing, then timeInterval has no meaning.

Returns:

Returns the time interval in milliseconds that can elapse between two writes to disk

getBytesThreshold

@Deprecated
long getBytesThreshold()

Deprecated. as of 6.5 use DiskStore.getQueueSize() instead.

Returns the number of unwritten bytes of data that can be enqueued before being written to disk. If this DiskWriteAttributes configures synchronous writing, then bytesThreshold has no meaning.

Returns:

Returns the number of bytes that can be buffered before being written to disk

equals

boolean equals(Object o)

Deprecated.

Two DiskWriteAttributes are equal if the both specify the synchronous writes, or they both specify asynchronous writes with the same time interval, bytes threshold, maxOplogSize and compaction values

Overrides:

equals in class Object

Returns:

true if o is equal else false
