Interface MeasureManager

All Known Implementing Classes:

SimpleMeasureManager

public interface MeasureManager

A MeasureManager aims at managing a set of Measures. Typically, a Measurable entity would create a single MeasureManager to store all the Measures it would like to support, each of them being identified by a key.

Because a Measure can be whether a PullMeasure or a PushMeasure, the two methods getPullMeasure(Object) and getPushMeasure(Object) are provided. It could be that a single Measure is also available through both (via a single instance implementing both interfaces or two different instances implementing each interface), leading to have both methods returning a non-null value for the same key.

Method Summary

Modifier and Type	Method and Description
Collection<Object>	getMeasureKeys() This method should return all the keys identifying the Measures managed by this MeasureManager.
<T> PullMeasure<T>	getPullMeasure(Object key)
<T> PushMeasure<T>	getPushMeasure(Object key)

Method Detail

getMeasureKeys

Collection<Object> getMeasureKeys()

This method should return all the keys identifying the Measures managed by this MeasureManager. More precisely, if getPullMeasure(Object) or getPushMeasure(Object) returns a non-null value for a given key, then this key should be returned by getMeasureKeys(). However, it is not because a key is returned by getMeasureKeys() that it necessarily has a PullMeasure or a PushMeasure returned by this MeasureManager.

Returns:

the set of keys identifying the managed Measures

getPullMeasure

<T> PullMeasure<T> getPullMeasure(Object key)

Parameters:

key - the key of the Measure

Returns:

the PullMeasure identified by this key

getPushMeasure

<T> PushMeasure<T> getPushMeasure(Object key)

Parameters:

key - the key of the Measure

Returns:

the PushMeasure identified by this key
