Constructor Detail

SiddhiDebugger

public SiddhiDebugger(ExecutionPlanContext executionPlanContext)

Create a new SiddhiDebugger instance for the given ExecutionPlanContext.

Parameters:

executionPlanContext - the ExecutionPlanContext

Method Detail

acquireBreakPoint

public void acquireBreakPoint(String queryName,
                              SiddhiDebugger.QueryTerminal queryTerminal)

Acquire the given breakpoint.

Parameters:

queryName - name of the Siddhi query

queryTerminal - IN or OUT endpoint of the query

releaseBreakPoint

public void releaseBreakPoint(String queryName,
                              SiddhiDebugger.QueryTerminal queryTerminal)

Release the given breakpoint from the SiddhiDebugger.

Parameters:

queryName - name of the Siddhi query

queryTerminal - IN or OUT endpoint of the query

releaseAllBreakPoints

public void releaseAllBreakPoints()

Release all the breakpoints from the Siddhi debugger. This may required to before stopping the debugger.

checkBreakPoint

public void checkBreakPoint(String queryName,
                            SiddhiDebugger.QueryTerminal queryTerminal,
                            ComplexEvent complexEvent)

Check for active breakpoint at the given endpoint and if there is an active checkpoint, block the thread and send the event for debug callback.

Parameters:

queryName - name of the Siddhi query

queryTerminal - IN or OUT endpoint of the query

complexEvent - the ComplexEvent which is waiting at the endpoint

next

public void next()

Release the current lock and wait for the events arrive to the next point. For this to work, the next endpoint is not required to be a checkpoint marked by the user. For example, if user adds breakpoint only for the IN of query 1, next will track the event in OUT of query 1.

play

public void play()

Release the current lock and wait for the next event arrive to the same break point.

setDebuggerCallback

public void setDebuggerCallback(SiddhiDebuggerCallback siddhiDebuggerCallback)

A callback to be called by the Siddhi debugger when reaching an active breakpoint.

Parameters:

siddhiDebuggerCallback - the SiddhiDebuggerCallback

getQueryState

public QueryState getQueryState(String queryName)

Get all the events stored in the Snapshotable entities of the given query.

Parameters:

queryName - name of the Siddhi query

Returns:

QueryState internal state of the query
