Class ContextManager

java.lang.Object

cc.redberry.core.context.ContextManager

public final class ContextManager
extends java.lang.Object

This class implements context management logic.

It holds current thread-local context of Redberry session (see description for Context class). It is possible to set context explicitly using setCurrentContext(Context) method. Each thread is linked to its own context. All child threads created via ExecutorService from getExecutorService() have same context.

Since:

1.0

Method Detail

getCurrentContext

public static Context getCurrentContext()

Returns the current context of Redberry session.

Returns:

the current context of Redberry session.

initializeNew

public static Context initializeNew()

This method initializes and sets current session context by the default value defined in DefaultContextFactory. After this step, all tensors that exist in the thread will be invalidated.

Returns:

created context

initializeNew

public static Context initializeNew(ContextSettings contextSettings)

This method initializes and sets current session context from the specified context settings (ContextSettings). After invocation of this method, all the tensors that exist in the current thread will be invalidated.

Returns:

created context

setCurrentContext

public static void setCurrentContext(Context context)

Sets current thread-local context to the specified one. After this step, all the tensors that exist in the thread will be invalidated.

Parameters:

context - context

getExecutorService

public static java.util.concurrent.ExecutorService getExecutorService()

Returns thread-local ExecutorService with fixed context. All threads linked to this ExecutorService will have same context.

Returns:

thread-local ExecutorService with fixed context
