Method Detail

values

public static FwdServerJMX.QueryProfiler[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FwdServerJMX.QueryProfiler c : FwdServerJMX.QueryProfiler.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FwdServerJMX.QueryProfiler valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

register

public void register(BooleanConsumer agent)

Register enable/disable setter

Specified by:

register in interface AgentRegistry<BooleanConsumer>

Parameters:

agent - enable/disable setter

getProfiler

public SimpleQueryProfiler getProfiler()

Retrieve the profiler back-end of this profiler.

Returns:

The simple query profiler
