Method Detail

runOp

public static void runOp(Op op,
                         CallExecutor callExecutor)
                  throws OpException

Execute an Op and time it.

Parameters:

op - the DataOp to execute

callExecutor -

Throws:

OpException

toString

public static java.lang.String toString(Op op)

Create a string representation of a DataOp.

Parameters:

op - the op to be toString'ed

Returns:

the string representation of a DataOp

logOpTiming

public static void logOpTiming(long t1,
                               long t2,
                               Op op)

Logs an OP-TIME message to the application log for the DataOp.

Parameters:

t1 - the start time

t2 - the end time

op - the op that was executed

getLoggableFieldsAndValues

public static java.util.Map getLoggableFieldsAndValues(Op op)
                                                throws java.lang.IllegalAccessException

Used by the ParamTreePathCallbackTransformer to generate a map of input fields and values.

Parameters:

op - the op to be examined

Returns:

a map of field name to value for what look like the Op's inputs

Throws:

java.lang.IllegalAccessException

See Also:

ParamTreePathCallbackTransformer.getOpParams(net.wgen.op.db.DatabaseCall)

looksLikeLoggableInput

public static boolean looksLikeLoggableInput(Op op,
                                             java.lang.reflect.Field field)

Called by the OpToStringBuilder to determine whether or not a field should be included in an Op's string representation. So, in other words, the field will be accepted for inclusion in the String if:

• avoid byte arrays and the OpExecutor field
• include _rootOp
• include field names that appear to have setters

Parameters:

op -

field -

Returns:

whether or not this field appears to be loggable

wrapSingleConnection

protected static MappedConnectionFactory wrapSingleConnection(java.sql.Connection connection,
                                                              TraceKey traceKey)

Convenience function to wrap single connections in a MappedConnectionFactory.

Parameters:

connection -

traceKey -

Returns:

a connection factory for the single connection
