```
public interface TransactionIntegration
```
Agroal provides an integration point for transaction systems to modify the behaviour of the pool. The transaction layer can control the lifecycle of connections and define what connections are acquired and when these return to the pool. It is responsible for commit or rollback of the database transaction.

Modifier and Type	Interface	Description
`static interface`	`TransactionIntegration.ResourceRecoveryFactory`	This interface is implemented by the connection factory so that it can provide recovery resources to the transaction layer.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addResourceRecoveryFactory(TransactionIntegration.ResourceRecoveryFactory factory)`	Agroal calls this method on init to register itself as a XA module capable of recovery.
`void`	`associate(TransactionAware transactionAware, XAResource xaResource)`	Agroal notifies the transaction layer a Tx aware resource (a connection) and it's corresponding XA resource were acquired.
`boolean`	`disassociate(TransactionAware transactionAware)`	Agroal notifies the transaction layer that a Tx aware resource (a connection) is about to be returned to the pool.
`TransactionAware`	`getTransactionAware()`	Agroal inquires the transaction layer for a Tx aware resource (a connection) that can be acquired.
`static TransactionIntegration`	`none()`	The default implementation of the transaction layer, that performs no actions.
`void`	`removeResourceRecoveryFactory(TransactionIntegration.ResourceRecoveryFactory factory)`	Agroal calls this method on shutdown to de-register itself as a XA module capable of recovery.

static TransactionIntegration none()
```
    The default implementation of the transaction layer, that performs no actions.
  - getTransactionAware
```
TransactionAware getTransactionAware()
                              throws SQLException
```
    Agroal inquires the transaction layer for a Tx aware resource (a connection) that can be acquired. Usually, if there is a resource already associated with the calling thread it is returned.
    
    Throws:
    
    SQLException
  - associate
```
void associate(TransactionAware transactionAware,
               XAResource xaResource)
        throws SQLException
```
    Agroal notifies the transaction layer a Tx aware resource (a connection) and it's corresponding XA resource were acquired. Usually, the resource is associated with the calling thread.
    
    Throws:
    
    SQLException
  - disassociate
```
boolean disassociate(TransactionAware transactionAware)
              throws SQLException
```
    Agroal notifies the transaction layer that a Tx aware resource (a connection) is about to be returned to the pool. Usually, the resource is disassociated from the calling thread and returned to the pool.
    
    Returns:
    
    true if the Tx aware should return to the pool, false if it should not.
    
    Throws:
    
    SQLException
  - addResourceRecoveryFactory
```
void addResourceRecoveryFactory(TransactionIntegration.ResourceRecoveryFactory factory)
```
    Agroal calls this method on init to register itself as a XA module capable of recovery.
  - removeResourceRecoveryFactory
```
void removeResourceRecoveryFactory(TransactionIntegration.ResourceRecoveryFactory factory)
```
    Agroal calls this method on shutdown to de-register itself as a XA module capable of recovery.
