Method Detail

getName

public java.lang.String getName()

Gets the name of the PN counter.

Specified by:

getName in interface NamedConfig

setName

public PNCounterConfig setName(java.lang.String name)

Sets the name of the PN counter.

Specified by:

setName in interface NamedConfig

Parameters:

name - the name of the PN counter

Returns:

the updated PN counter config

isStatisticsEnabled

public boolean isStatisticsEnabled()

Checks if statistics are enabled for this PN counter

Returns:

true if enabled, false otherwise

setStatisticsEnabled

public PNCounterConfig setStatisticsEnabled(boolean statisticsEnabled)

Enables or disables statistics for this PN counter

Parameters:

statisticsEnabled - true to enable statistics, false to disable

Returns:

the updated PN counter config

getReplicaCount

public int getReplicaCount()

Returns the number of replicas on which state for this PN counter will be kept. This number applies in quiescent state, if there are currently membership changes or clusters are merging, the state may be temporarily kept on more replicas.

Returns:

the number of replicas for the CRDT state

setReplicaCount

public PNCounterConfig setReplicaCount(int replicaCount)

Sets the number of replicas on which state for this PN counter will be kept. This number applies in quiescent state, if there are currently membership changes or clusters are merging, the state may be temporarily kept on more replicas.

The provided replicaCount must be between 1 and 2147483647.

Parameters:

replicaCount - the number of replicas for the CRDT state

Returns:

the updated PN counter config

Throws:

InvalidConfigurationException - if the replicaCount is less than 1

getSplitBrainProtectionName

public java.lang.String getSplitBrainProtectionName()

Returns the split brain protection name for operations.

Returns:

the split brain protection name

setSplitBrainProtectionName

public PNCounterConfig setSplitBrainProtectionName(java.lang.String splitBrainProtectionName)

Sets the split brain protection name for operations.

Parameters:

splitBrainProtectionName - the split brain protection name

Returns:

the updated PN counter config

getFactoryId
