Method Detail

getClassName

String getClassName()

Return the internal name of the class.

Returns:

The class name.

isTracedClass

boolean isTracedClass()

Returns true iff this class is monitored.

Returns:

true iff this class has one or more MM annotations.

getAnnotationToHolderName

Map<String,String> getAnnotationToHolderName()

Map from MM annotation name to the name of the holder field that contains the SynchronizedHolder for the corresponding MethodMonitor. The domain of this map is the set of MM annotations on this class.

Returns:

Map from MM annotations defined on this class to the names of the holder fields.

classifyMethod

EnhancedClassData.MethodType classifyMethod(String fullMethodDescriptor)

Classify the method.

Parameters:

fullMethodDescriptor - The full method descriptor of the method.

Returns:

The kind of the corresponding method.

getHolderName

String getHolderName(String fullMethodDescriptor)

Name of the holder fields corresponding to a particular method. Note that the full descriptor (name + arg/return descriptor) is used to unambiguously identify the method in the class.

Parameters:

fullMethodDescriptor - The full method descriptor of the method.

Returns:

The name of the holder field used for this method.

getMethodNames

List<String> getMethodNames()

List of method names for all MM methods and info methods in the class. Order is significant, as the index of the method in the list is the ordinal used to represent it. This list is in sorted order.

Returns:

List of all method tracing names in sorted order.

getTimingPointNames

List<String> getTimingPointNames()

List of timing point names corresponding to method names. For monitored methods, this is just the method name. For info methods whose tpType is not NONE, this is specified in tpName.

Returns:

List of timing point names, in the same order as in getMethodTracingNames.

getDescriptions

List<String> getDescriptions()

List of descriptions of monitored methods and info methods. If no description was given in the annotations, the value is "".

Returns:

List of descriptions in the same order as in getMethodTracingNames.

getTimingPointTypes

List<TimingPointType> getTimingPointTypes()

List of timing point types of monitored methods and info methods. The list contains BOTH for a monitored method. An info method that does not represent a timing point is represented by NONE.

Returns:

List of TimingPointTypes in the same order as in getMethodTracingNames.

getMethodMMAnnotationName

List<String> getMethodMMAnnotationName()

List of annotation names for each info method and monitored method. It is interpreted as follows:

• If the entry in the list is not null, it is the only annotation applicable to this method. This is the case for monitored methods.
• If the entry in the list is null, all annotations on the enclosing class apply to this method. This is the case for an InfoMethod, which can be called from any monitored method regardless of the annotation on the monitored method.

Returns:

List of annotation names for methods.

getMethodIndex

int getMethodIndex(String methodName)

Index of method name in the list of method names.

Parameters:

methodName - The method name as defined for tracing.

Returns:

the method index

updateInfoDesc

void updateInfoDesc()

Enhance all of the descriptors for infoMethods.
