Detailed Description

A class for the cross-thread manipulatable value. Can be used in situations where a value needs to be manipulated (read and/or written) from a thread context. The shadow value of the node is created in the thread context and can be manipulated there. An addition, a thread context value copy is created for direct manipulation in the thread context and to determine if the thread context value has been changed and the change should be synced back to the node context. All value synchronization between the threads is done without mutexes - only using lockfree commands queues.

Note: The template type of the class can be different from the node that will be synced - then value converting occurs on sync time.

CrossThreadValueNode constructor parameters:

• node - The node to create the cross-thread manipulatable value for
• threadContextRunQueue - The run queue for the thread context to post value-change commands to

  Note: When threadContextRunQueue is not set (nullptr), then the syncing will be unidirectional - i.e. value is not synced from node context to thread context. Value can then only be synced from thread context to node context (using AddSyncThreadContextValueToNodeQueue() method). This unidirectional syncing can be useful when the value is only written from the thread context and read in the node context (like updating values of read-only output signals, properties or arguments from thread).

• onNodeRemove - Optional callback to be called when the node context reports node was removed

Note: The constructor of the CrossThreadValueNode should be always called from thread context and with the node context GetMemberAccessMutex() locked.
