Enum AGPoolProp

java.lang.Object

java.lang.Enum<AGPoolProp>

com.franz.agraph.pool.AGPoolProp

All Implemented Interfaces:

Serializable, Comparable<AGPoolProp>

public enum AGPoolProp
extends Enum<AGPoolProp>

Property names for AGPoolConfig.

Property names to open a AGRepositoryConnection.

TODO: AGRepositoryConnection.setSessionLoadInitFile(boolean)

TODO: AGRepositoryConnection.addSessionLoadScript(String)

Many of these properties are specified and used by GenericObjectPool.

Enum Constant Summary

Enum Constants

Enum Constant and Description
initialSize When the pool is created, this many connections will be initialized, then returned to the pool.
lifo Boolean property, true means LIFO and false means FIFO retrieval of objects from pool
maxActive Max number of connections that can be allocated by the pool.
maxIdle
maxWait milliseconds to wait to borrow before throwing NoSuchElementException
minEvictableIdleTimeMillis
minIdle
numTestsPerEvictionRun
shutdownHook When the pool is created, if this is true (default is false), a hook will be registered to close the pool.
softMinEvictableIdleTimeMillis
testOnBorrow Calls AGRepositoryConnection.size(org.eclipse.rdf4j.model.Resource...).
testOnReturn Calls AGRepositoryConnection.size(org.eclipse.rdf4j.model.Resource...).
testWhileIdle
timeBetweenEvictionRunsMillis
warmup Boolean property, if true warmup is executed during pool creation.
warmupIncludeStrings Boolean property, set to false to exclude the string table from a warmup
warmupIncludeTriples Boolean property, set to false to exclude triple indices from a warmup

Enum Constant Detail

initialSize

public static final AGPoolProp initialSize

When the pool is created, this many connections will be initialized, then returned to the pool.

See Also:

AGPoolConfig.initialSize

shutdownHook

public static final AGPoolProp shutdownHook

When the pool is created, if this is true (default is false), a hook will be registered to close the pool. Connections will be closed whether idle or not.

When the pool is closed, from outside of the hook, the hook will be removed so it is not leaked in the list of hooks.

See Also:

AGPoolConfig.shutdownHook, Runtime.addShutdownHook(Thread)

minIdle

public static final AGPoolProp minIdle

See Also:

GenericObjectPool.setMinIdle(int)

maxIdle

public static final AGPoolProp maxIdle

See Also:

GenericObjectPool.setMaxIdle(int)

maxActive

public static final AGPoolProp maxActive

Max number of connections that can be allocated by the pool. If multiple clients (or different pools), are using the same AllegroGraph Server, this value should be set to something less than the SessionPorts. See Session Port Setup.

See Also:

BaseGenericObjectPool.setMaxTotal(int)

maxWait

public static final AGPoolProp maxWait

milliseconds to wait to borrow before throwing NoSuchElementException

See Also:

BaseGenericObjectPool.setMaxWaitMillis(long)

testOnBorrow

public static final AGPoolProp testOnBorrow

Calls AGRepositoryConnection.size(org.eclipse.rdf4j.model.Resource...).

Redundant because AGConnFactory.activateObject(PooledObject) always calls AGRepositoryConnection.rollback().

See Also:

BaseGenericObjectPool.setTestOnBorrow(boolean), AGConnFactory.validateObject(PooledObject)

testOnReturn

public static final AGPoolProp testOnReturn

Calls AGRepositoryConnection.size(org.eclipse.rdf4j.model.Resource...).

See Also:

BaseGenericObjectPool.setTestOnReturn(boolean), AGConnFactory.validateObject(PooledObject)

timeBetweenEvictionRunsMillis

public static final AGPoolProp timeBetweenEvictionRunsMillis

See Also:

BaseGenericObjectPool.setTimeBetweenEvictionRunsMillis(long)

minEvictableIdleTimeMillis

public static final AGPoolProp minEvictableIdleTimeMillis

See Also:

BaseGenericObjectPool.setMinEvictableIdleTimeMillis(long)

testWhileIdle

public static final AGPoolProp testWhileIdle

See Also:

BaseGenericObjectPool.setTestWhileIdle(boolean)

softMinEvictableIdleTimeMillis

public static final AGPoolProp softMinEvictableIdleTimeMillis

See Also:

BaseGenericObjectPool.setSoftMinEvictableIdleTimeMillis(long)

numTestsPerEvictionRun

public static final AGPoolProp numTestsPerEvictionRun

See Also:

BaseGenericObjectPool.setNumTestsPerEvictionRun(int)

warmup

public static final AGPoolProp warmup

Boolean property, if true warmup is executed during pool creation.

warmupIncludeStrings

public static final AGPoolProp warmupIncludeStrings

Boolean property, set to false to exclude the string table from a warmup

warmupIncludeTriples

public static final AGPoolProp warmupIncludeTriples

Boolean property, set to false to exclude triple indices from a warmup

lifo

public static final AGPoolProp lifo

Boolean property, true means LIFO and false means FIFO retrieval of objects from pool

Method Detail

values

public static AGPoolProp[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AGPoolProp c : AGPoolProp.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AGPoolProp valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
