Method Detail

createFast

public static GammaStm createFast()

Creates a GammaStm implementation optimized for speed. This method probably will be invoked by the GlobalStmInstance.

Returns:

the created GammaStm.

newDefaultTxn

public final GammaTxn newDefaultTxn()

Description copied from interface: Stm

Starts a default Txn that is useful for testing/experimentation purposes. This method is purely for easy to use access, but doesn't provide any configuration options. See the Stm.newTxnFactoryBuilder() for something more configurable. In mose cases this is not the method you want to use to manage transactions.

Transactions returned by this method are not speculative.

Specified by:

newDefaultTxn in interface Stm

Returns:

the new default Txn.

getDefaultTxnExecutor

public final GammaTxnExecutor getDefaultTxnExecutor()

Description copied from interface: Stm

Returns the default TxnExecutor that is useful for testing/experimentation purposes. This method is purely for easy to use access, but it doesn't provide any configuration options. See the Stm.newTxnFactoryBuilder() for something more configurable.

Transactions used in this Block are not speculative.

Specified by:

getDefaultTxnExecutor in interface Stm

Returns:

the default TxnExecutor.

newOrElseBlock

public final GammaOrElseBlock newOrElseBlock()

Description copied from interface: Stm

Creates an OrElseBlock.

Specified by:

newOrElseBlock in interface Stm

Returns:

the created OrElseBlock.

getGlobalConflictCounter

public final GlobalConflictCounter getGlobalConflictCounter()

getDefaultRefFactory

public final GammaTxnRefFactory getDefaultRefFactory()

Description copied from interface: Stm

Returns the default TxnRefFactory that can be used for easy and cheap access to a reference factory instead of setting one up through the TxnRefFactoryBuilder.

Specified by:

getDefaultRefFactory in interface Stm

Returns:

the default TxnRefFactory.

newTxnFactoryBuilder

public final GammaTxnFactoryBuilder newTxnFactoryBuilder()

Description copied from interface: Stm

Gets the TxnFactoryBuilder that needs to be used to execute a Txn created by this Stm. See the TxnFactoryBuilder for more info. The TxnFactoryBuilder also is responsible for creating the TxnExecutor since the Txn and TxnExecutor can be tightly coupled.

Specified by:

newTxnFactoryBuilder in interface Stm

Returns:

the TxnFactoryBuilder that is used to execute transactions on this Stm.

getDefaultTxnCollectionFactory

public final TxnCollectionsFactory getDefaultTxnCollectionFactory()

Description copied from interface: Stm

Gets the default TxnCollectionsFactory.

Specified by:

getDefaultTxnCollectionFactory in interface Stm

Returns:

the default TxnCollectionsFactory.

getTxRefFactoryBuilder

public final GammaTxnRefFactoryBuilder getTxRefFactoryBuilder()

Description copied from interface: Stm

Gets the TxnRefFactoryBuilder.

Specified by:

getTxRefFactoryBuilder in interface Stm

Returns:

the TxnRefFactoryBuilder.
