ESQL context tree functions

ESQL provides functions that support operations on the context tree.

ESQL provides a CONTEXTREFERENCE function, which provides access to node sections from the flow propagation path. The function returns a REFERENCE to the context tree section that is named by the nodeLabel parameter. For more information, see CONTEXTREFERENCE function.

ESQL provides a CONTEXTINVOCATIONNODE function, which returns the captured node section for a message flow input node, and enables access to the payload that came into the message flow. You do not need to know the name of the input node. For more information, see CONTEXTINVOCATIONNODE function.

For more information about message trees, see Logical tree (message assembly).
