Class RepeatSynchronizationManager
java.lang.Object
org.springframework.batch.repeat.support.RepeatSynchronizationManager
Global variable support for repeat clients. Normally it is not necessary for clients to
be aware of the surrounding environment because a
RepeatCallback can always use
the context it is passed by the enclosing RepeatOperations. But occasionally it
might be helpful to have lower level access to the ongoing RepeatContext so we
provide a global accessor here. The mutator methods (clear() and
register(RepeatContext) should not be used except internally by
RepeatOperations implementations.- Author:

Method Details
-
getContext
Getter for the current context. A context is shared by all items in the batch, so this method is intended to return the same context object independent of whether the callback is running synchronously or asynchronously with the surroundingRepeatOperations.- Returns:
- the current
RepeatContextor null if there is none (if we are not in a batch).
-
setCompleteOnly
public static void setCompleteOnly()Convenience method to set the current repeat operation to complete if it exists. -
register
Method for registering a context - should only be used byRepeatOperationsimplementations to ensure thatgetContext()always returns the correct value.- Parameters:
context- a new context at the start of a batch.- Returns:
- the old value if there was one.
-
clear
Clear the current context at the end of a batch - should only be used byRepeatOperationsimplementations.- Returns:
- the old value if there was one.

setAncestorsCompleteOnly
public static void setAncestorsCompleteOnly()Set current session and all ancestors (via parent) to complete.,
