Field Detail

CONCURRENCY_LEVEL

public static final org.infinispan.commons.configuration.attributes.AttributeDefinition<Integer> CONCURRENCY_LEVEL

ISOLATION_LEVEL

public static final org.infinispan.commons.configuration.attributes.AttributeDefinition<org.infinispan.util.concurrent.IsolationLevel> ISOLATION_LEVEL

LOCK_ACQUISITION_TIMEOUT

public static final org.infinispan.commons.configuration.attributes.AttributeDefinition<Long> LOCK_ACQUISITION_TIMEOUT

USE_LOCK_STRIPING

public static final org.infinispan.commons.configuration.attributes.AttributeDefinition<Boolean> USE_LOCK_STRIPING

Method Detail

getElementDefinition

public org.infinispan.commons.configuration.elements.ElementDefinition getElementDefinition()

Specified by:

getElementDefinition in interface BaseConfigurationInfo

Returns:

the ElementDefinition of the configuration.

concurrencyLevel

public int concurrencyLevel()

Concurrency level for lock containers. Adjust this value according to the number of concurrent threads interacting with Infinispan. Similar to the concurrencyLevel tuning parameter seen in the JDK's ConcurrentHashMap.

isolationLevel

public org.infinispan.util.concurrent.IsolationLevel isolationLevel()

Cache isolation level. Infinispan only supports READ_COMMITTED or REPEATABLE_READ isolation levels. See http://en.wikipedia.org/wiki/Isolation_level for a discussion on isolation levels.

lockAcquisitionTimeout

public long lockAcquisitionTimeout()

Maximum time to attempt a particular lock acquisition

lockAcquisitionTimeout

public LockingConfiguration lockAcquisitionTimeout(long timeout)

useLockStriping

public boolean useLockStriping()

If true, a pool of shared locks is maintained for all entries that need to be locked. Otherwise, a lock is created per entry in the cache. Lock striping helps control memory footprint but may reduce concurrency in the system.

attributes

public org.infinispan.commons.configuration.attributes.AttributeSet attributes()

Specified by:

attributes in interface BaseConfigurationInfo

Returns:

the AttributeSet declared by the configuration.

toString

public String toString()

equals

public boolean equals(Object obj)

hashCode

public int hashCode()
