                  io.temporal.api.common.v1.Header header,
                  UpdateProtocolCallback callbacks)

Handle an update workflow execution event

eventLoop

boolean eventLoop()

Returns:

true if the execution of the workflow method is finished or an exit was explicitly called by it

getOutput

java.util.Optional<io.temporal.api.common.v1.Payloads> getOutput()

Returns:

null means no output yet

cancel

void cancel(java.lang.String reason)

close

void close()

query

java.util.Optional<io.temporal.api.common.v1.Payloads> query(io.temporal.api.query.v1.WorkflowQuery query)

Called after all history is replayed and workflow cannot make any progress if workflow task is a query.

Parameters:

query - arguments

Returns:

query result

getWorkflowContext

WorkflowContext getWorkflowContext()

Returns:

the fullest context of the workflow possible
