GroovyRunnerRegistry (Groovy 4.0.23)

org.apache.groovy.plugin.GroovyRunnerRegistry

All Implemented Interfaces and Traits:

Map, Iterable
```
public class GroovyRunnerRegistry
extends Object
implements Map, Iterable
```
Registry of services that implement the GroovyRunner interface.
This registry makes use of the ServiceLoader facility. The preferred method for registering new GroovyRunner providers is to place them in a provider-configuration file in the resource directory META-INF/services. The preferred method for accessing the registered runners is by making use of the Iterable interface using an enhanced for-loop.
For compatibility with previous versions, this registry implements the Map interface. All null keys and values will be ignored and no exception thrown, except where noted.
By default the registry contains runners that are capable of running JUnit 3 and JUnit 4 test classes if those libraries are available to the class loader.
Since:
2.5.0

Methods Summary

Methods
Type Params	Return Type	Name and description
	`public void`	`clear()` Clears all registered runners from the registry and resets the registry so that it contains only the default set of runners.
	`public boolean`	`containsKey(Object key)` Returns `true` if a runner was registered with the specified key.
	`public boolean`	`containsValue(Object runner)` Returns `true` if registry contains the given runner instance.
	`public Set<Entry<String, GroovyRunner>>`	`entrySet()` Returns a set of entries for registered runners.
	`public GroovyRunner`	`get(Object key)` Returns the registered runner for the specified key.
	`public static GroovyRunnerRegistry`	`getInstance()` Returns a reference to the one and only registry instance.
	`public boolean`	`isEmpty()` Returns `true` if the registry contains no runners, else `false`.
	`public Iterator<GroovyRunner>`	`iterator()` Returns an iterator for all runners that are registered.
	`public Set<String>`	`keySet()` Set of all keys associated with registered runners.
	`public void`	`load(ClassLoader classLoader)` Loads GroovyRunner instances using the ServiceLoader facility.
	`public GroovyRunner`	`put(String key, GroovyRunner runner)` Registers a runner with the specified key.
	`public void`	`putAll(Map<? extends String, ? extends GroovyRunner> m)` Adds all entries from the given Map to the registry.
	`public GroovyRunner`	`remove(Object key)` Removes a registered runner from the registry.
	`public int`	`size()` Returns the number of registered runners.
	`public String`	`toString()`

- Method Detail
  - @Override
    public void clear()
    
    Clears all registered runners from the registry and resets the registry so that it contains only the default set of runners.
  - @Override
    public boolean containsKey(Object key)
    
    Returns true if a runner was registered with the specified key.
    Parameters:
    key - for the registered runner
    Returns:
    true if a runner was registered with given key
  - @Override
    public boolean containsValue(Object runner)
    
    Returns true if registry contains the given runner instance.
    Parameters:
    runner - instance of a GroovyRunner
    Returns:
    true if the given runner is registered
  - @Override
    public Set<Entry<String, GroovyRunner>> entrySet()
    
    Returns a set of entries for registered runners. This is a snapshot of the registry and any subsequent registry changes will not be reflected in the set.
    Returns:
    an unmodifiable set of registered runner entries
  - @Override
    public GroovyRunner get(Object key)
    
    Returns the registered runner for the specified key.
    Parameters:
    key - used to look up the runner
    Returns:
    the runner registered with the given key
  - public static GroovyRunnerRegistry getInstance()
    
    Returns a reference to the one and only registry instance.
    Returns:
    registry instance
  - @Override
    public boolean isEmpty()
    
    Returns true if the registry contains no runners, else false.
    Returns:
    true if no runners are registered
  - @Override
    public Iterator<GroovyRunner> iterator()
    
    Returns an iterator for all runners that are registered. The returned iterator is a snapshot of the registry at the time the iterator is created. This iterator does not support removal.
    Returns:
    iterator for all registered runners
  - @Override
    public Set<String> keySet()
    
    Set of all keys associated with registered runners. This is a snapshot of the registry and any subsequent registry changes will not be reflected in the set.
    Returns:
    an unmodifiable set of keys for registered runners
  - public void load(ClassLoader classLoader)
    
    Loads GroovyRunner instances using the ServiceLoader facility.
    Parameters:
    classLoader - used to locate provider-configuration files and classes
  - @Override
    public GroovyRunner put(String key, GroovyRunner runner)
    
    Registers a runner with the specified key.
    Parameters:
    key - to associate with the runner
    runner - the runner to register
    Returns:
    the previously registered runner for the given key, if no runner was previously registered for the key then null
  - @Override
    public void putAll(Map<? extends String, ? extends GroovyRunner> m)
    
    Adds all entries from the given Map to the registry. Any entries in the provided Map that contain a null key or value will be ignored.
    throws:
    NullPointerException if the given Map is null
    
    Parameters:
    m - entries to add to the registry
  - @Override
    public GroovyRunner remove(Object key)
    
    Removes a registered runner from the registry.
    Parameters:
    key - of the runner to remove
    Returns:
    the runner instance that was removed, if no runner instance was removed then null
  - @Override
    public int size()
    
    Returns the number of registered runners.
    Returns:
    number of registered runners
  - @Override
    public String toString()
  - @Override
    public Collection<GroovyRunner> values()
    
    Returns a collection of all registered runners. This is a snapshot of the registry and any subsequent registry changes will not be reflected in the collection.
    Returns:
    an unmodifiable collection of registered runner instances
