Method Detail

markForUpdate

public void markForUpdate(DataContainer container,
                          boolean writeSkewCheck)

Description copied from interface: NodeSPI

Marks a node for updating. Internally, this creates a copy of the delegate and performs any checks necessary to maintain isolation level.

Only used with MVCC.

Specified by:

markForUpdate in interface NodeSPI

Overrides:

markForUpdate in class ReadCommittedNode

Parameters:

container - data container

writeSkewCheck - if true, and the node supports write skew checking, nodes are tested for write skews.

updateNode

protected void updateNode(Fqn fqn,
                          InvocationContext ctx,
                          DataContainer dataContainer)

Description copied from class: ReadCommittedNode

Updates state changes on the current node in the underlying data structure.

Overrides:

updateNode in class ReadCommittedNode

ctx - invocation context

dataContainer - data container
