AbstractRegistry (Spectator)

java.lang.Object
- com.netflix.spectator.api.AbstractRegistry

All Implemented Interfaces:

Registry, Iterable<Meter>

Direct Known Subclasses:

DefaultRegistry
```
public abstract class AbstractRegistry
extends Object
implements Registry
```
Base class to make it easier to implement a simple registry that only needs to customise the types returned for Counter, DistributionSummary, and Timer calls.

```
public AbstractRegistry(Clock clock)
```
    Create a new instance.
    
    Parameters:
    clock - Clock used for performing all timing measurements.
- Method Detail
  - newCounter
```
protected abstract Counter newCounter(Id id)
```
    Create a new counter instance for a given id.
    
    Parameters:
    id - Identifier used to lookup this meter in the registry.
    
    Returns:
    New counter instance.
  - newDistributionSummary
```
protected abstract DistributionSummary newDistributionSummary(Id id)
```
    Create a new distribution summary instance for a given id.
    
    Parameters:
    id - Identifier used to lookup this meter in the registry.
    
    Returns:
    New distribution summary instance.
  - newTimer
```
protected abstract Timer newTimer(Id id)
```
    Create a new timer instance for a given id.
    
    Parameters:
    id - Identifier used to lookup this meter in the registry.
    
    Returns:
    New timer instance.
  - clock
```
public final Clock clock()
```
    Description copied from interface: Registry
    
    The clock used by the registry for timing events.
    
    Specified by:
    
    clock in interface Registry
  - createId
```
public final Id createId(String name)
```
    Description copied from interface: Registry
    
    Creates an identifier for a meter. All ids passed into other calls should be created by the registry.
    
    Specified by:
    
    createId in interface Registry
    
    Parameters:
    name - Description of the measurement that is being collected.
  - createId
```
public final Id createId(String name,
          Iterable<Tag> tags)
```
    Description copied from interface: Registry
    
    Creates an identifier for a meter. All ids passed into other calls should be created by the registry.
    
    Specified by:
    
    createId in interface Registry
    
    Parameters:
    name - Description of the measurement that is being collected.
    tags - Other dimensions that can be used to classify the measurement.
  - register
```
public final void register(Meter meter)
```
    Description copied from interface: Registry
    
    Add a custom meter to the registry.
    
    Specified by:
    
    register in interface Registry
  - counter
```
public final Counter counter(Id id)
```
    Description copied from interface: Registry
    
    Measures the rate of some activity. A counter is for continuously incrementing sources like the number of requests that are coming into a server.
    
    Specified by:
    
    counter in interface Registry
    
    Parameters:
    id - Identifier created by a call to Registry.createId(java.lang.String)
  - distributionSummary
```
public final DistributionSummary distributionSummary(Id id)
```
    Description copied from interface: Registry
    
    Measures the rate and variation in amount for some activity. For example, it could be used to get insight into the variation in response sizes for requests to a server.
    
    Specified by:
    
    distributionSummary in interface Registry
    
    Parameters:
    id - Identifier created by a call to Registry.createId(java.lang.String)
  - timer
```
public final Timer timer(Id id)
```
    Description copied from interface: Registry
    
    Measures the rate and time taken for short running tasks.
    
    Specified by:
    
    timer in interface Registry
    
    Parameters:
    id - Identifier created by a call to Registry.createId(java.lang.String)
  - get
```
public final Meter get(Id id)
```
    Description copied from interface: Registry
    
    Returns the meter associated with a given id.
    
    Specified by:
    
    get in interface Registry
    
    Parameters:
    id - Identifier for the meter.
    
    Returns:
    Instance of the meter or null if there is no match.
  - iterator
```
public final Iterator<Meter> iterator()
```
    Description copied from interface: Registry
    
    Iterator for traversing the set of meters in the registry.
    
    Specified by:
    
    iterator in interface Registry
    
    Specified by:
    
    iterator in interface Iterable<Meter>
