@Immutable
public static class SystemFunctions.CreateVersionNodeFunction
extends SystemFunctions.VersionHistoryFunction

The Function implementation that efficiently updates the JCR version history and storage with a new version of a node being checked in. This function will correctly update the version storage and output the values for the "mix:versionable" properties. Note, however, that the caller of this function must walk the children of the versionable node and create version nodes appropriately.

Note that this function assumes that the version history already exists for the versionable node.

This function requires the following inputs:

The function produces the following outputs:

Method Detail

run

public void run(FunctionContext context)
The method called to invoke the function. The implementation can obtain from the supplied FunctionContext the inputs to the function, a FunctionContext.builder() that can be used to create and immediately execute other requests, the context of execution, the location in the graph where the function is being applied, and other information needed during execution. The implementation even uses the supplied FunctionContext to write output parameters.

Specified by:
run in class Function
Parameters:
context - the context in which the function is being invoked, and which contains the inputs, the outputs, and methods to create and invoke other requests on the connector
