Method Summary

Modifier and Type	Method	Description
Collection<Accessor>	getAccessors()	INTERNAL: Always use writeConnection.
boolean	isExclusiveConnectionRequired()	INTERNAL: This method is called in case externalConnectionPooling is used.
boolean	isExclusiveIsolatedClientSession()	PUBLIC: Return if this session is an exclusive isolated client session.
void	postAcquireConnection(Accessor accessor)	INTERNAL: This method rises appropriate for the session event(s) right after connection is acquired.
void	preReleaseConnection(Accessor accessor)	INTERNAL: This method rises appropriate for the session event(s) right before the connection is released.
protected void	releaseWriteConnection()	INTERNAL: As this session type should maintain it's transaction for its entire life- cycle we will wait for 'release' before releasing connection.
void	setAccessor(Accessor accessor)	INTERNAL: Provided for consistency.
protected boolean	shouldExecuteLocally(DatabaseQuery query)	INTERNAL: Helper method to calculate whether to execute this query locally or send it to the server session.

 ConnectionPolicy connectionPolicy)

ExclusiveIsolatedClientSession

public ExclusiveIsolatedClientSession(ServerSession parent,
 ConnectionPolicy connectionPolicy,
 Map properties)

Method Details

getAccessors

public Collection<Accessor> getAccessors()

INTERNAL: Always use writeConnection.

Overrides:

getAccessors in class ClientSession

setAccessor

public void setAccessor(Accessor accessor)

INTERNAL: Provided for consistency.

Overrides:

setAccessor in class AbstractSession

releaseWriteConnection

protected void releaseWriteConnection()

INTERNAL: As this session type should maintain it's transaction for its entire life- cycle we will wait for 'release' before releasing connection. By making this method a no-op the connection will not be released until 'release()' is called on the client session.

Overrides:

releaseWriteConnection in class ClientSession

postAcquireConnection

public void postAcquireConnection(Accessor accessor)

INTERNAL: This method rises appropriate for the session event(s) right after connection is acquired.

Overrides:

postAcquireConnection in class AbstractSession

preReleaseConnection

public void preReleaseConnection(Accessor accessor)

INTERNAL: This method rises appropriate for the session event(s) right before the connection is released.

Overrides:

preReleaseConnection in class AbstractSession

isExclusiveConnectionRequired

public boolean isExclusiveConnectionRequired()

INTERNAL: This method is called in case externalConnectionPooling is used. If returns true, accessor used by the session keeps its connection open until released by the session.

Overrides:

isExclusiveConnectionRequired in class ClientSession

isExclusiveIsolatedClientSession

public boolean isExclusiveIsolatedClientSession()

PUBLIC: Return if this session is an exclusive isolated client session.

Overrides:

isExclusiveIsolatedClientSession in class AbstractSession

shouldExecuteLocally

protected boolean shouldExecuteLocally(DatabaseQuery query)

INTERNAL: Helper method to calculate whether to execute this query locally or send it to the server session.

Overrides:

shouldExecuteLocally in class IsolatedClientSession
