Method Detail

getMonitoringValuesProviders

List<IMonitorValuesProvider> getMonitoringValuesProviders()

Returns a view of aggregation values stored in this monitor context.

There is no guarantee whether the returned list will or will not reflect further changes made in this monitor context.

Returns:

an immutable list with the providers currently set in this monitor context.

Since:

9.0.0

addValues

default IMonitorValuesProvider addValues(String fieldId,
                                         Serializable... values)

Stores a monitoring value in this monitor context. removeValues(IMonitorValuesProvider) should be called (use a try/finally block to ensure that) to remove the aggregation value set when it should no longer be applied.

Typical use for setting an aggregation value follows below:

 final String monitoringFieldId = ...;
 final Serializable value = ...;
 IMonitorValuesProvider provider = monitorContext.addValues(monitoringFieldId, value);
 try
 {
   // execution block that will have the set aggregation value as default
 }
 finally
 {
   monitorContext.removeValues(provider);
 }
 

Parameters:

fieldId - the field identifier.

values - the values to set for the field.

Returns:

the created IMonitorValuesProvider to provide the given values.

Since:

9.0.0

addValues

default IMonitorValuesProvider addValues(String fieldId,
                                         List<? extends Serializable> values)

Stores a monitoring value in this monitor context. removeValues(IMonitorValuesProvider) should be called (use a try/finally block to ensure that) to remove the aggregation value set when it should no longer be applied.

Typical use for setting an aggregation value follows below:

 final String monitoringFieldId = ...;
 final Serializable value = ...;
 IMonitorValuesProvider provider = monitorContext.addValues(monitoringFieldId, value);
 try
 {
   // execution block that will have the set aggregation value as default
 }
 finally
 {
   monitorContext.removeValues(provider);
 }
 

Parameters:

fieldId - the field identifier.

values - the values to set for the field.

Returns:

the created IMonitorValuesProvider to provide the given values.

Since:

9.0.0

addValues

default IMonitorValuesProvider addValues(Map<String,List<? extends Serializable>> fieldValues)

Stores a monitoring value in this monitor context. removeValues(IMonitorValuesProvider) should be called (use a try/finally block to ensure that) to remove the aggregation value set when it should no longer be applied.

Typical use for setting an aggregation value follows below:

 final String monitoringFieldId = ...;
 final Serializable value = ...;
 IMonitorValuesProvider provider = monitorContext.addValues(monitoringFieldId, value);
 try
 {
   // execution block that will have the set aggregation value as default
 }
 finally
 {
   monitorContext.removeValues(provider);
 }
 

Parameters:

fieldValues - the field values to set for the field.

Returns:

the created IMonitorValuesProvider to provide the given values.

Since:

9.0.0

addValues

void addValues(IMonitorValuesProvider... fieldValues)

Stores a monitoring value in this monitor context. removeValues(IMonitorValuesProvider) should be called (use a try/finally block to ensure that) to remove the aggregation value set when it should no longer be applied.

Typical use for setting an aggregation value follows below:

 IMonitorValuesProvider provider = new MyValueProvider();
 monitorContext.addValues(provider);
 try
 {
   // execution block that will have the set aggregation value as default
 }
 finally
 {
   monitorContext.removeValues(provider);
 }
 

Parameters:

fieldValues - the field values providers to set for the field.

Since:

9.0.0

removeValues

void removeValues(IMonitorValuesProvider provider)

Removes an aggregation value from the current monitor context.

Parameters:

provider - the previously added provider.

Since:

9.0.0

Since:

9.0.0

isEnabled

boolean isEnabled()

Returns whether the current monitor context is enabled.

Returns:

whether the current monitor context is enabled.

Since:

11.0.0

isEmpty
