Class ValidatingMappedConfigurationWrapper<K,V>

java.lang.Object

org.apache.tapestry5.ioc.internal.AbstractConfigurationImpl<V>

org.apache.tapestry5.ioc.internal.ValidatingMappedConfigurationWrapper<K,V>

Type Parameters:

K - the key type

V - the value type

All Implemented Interfaces:

MappedConfiguration<K,V>

public class ValidatingMappedConfigurationWrapper<K,V>
extends AbstractConfigurationImpl<V>
implements MappedConfiguration<K,V>

A wrapper around a Map that provides the MappedConfiguration interface, and provides two forms of validation for mapped configurations:

• If either key or value is null, then a warning is logged
• If the key has previously been stored (by some other ContributionDef, then a warning is logged

When a warning is logged, the key/value pair is not added to the delegate. Handles instantiation of instances.

Method Detail

add

public void add(K key,
                V value)

Description copied from interface: MappedConfiguration

Adds a keyed object to the service's contribution.

Specified by:

add in interface MappedConfiguration<K,V>

Parameters:

key - unique id for the value

value - to contribute

addInstance

public void addInstance(K key,
                        Class<? extends V> clazz)

Description copied from interface: MappedConfiguration

Adds a keyed object as an instantiated instance (with dependencies injected) of a class. When the value type is an interface and the class to be contributed is a local file, then a reloadable proxy for the value class will be created and contributed.

Specified by:

addInstance in interface MappedConfiguration<K,V>

Parameters:

key - unique id for the value

clazz - class to instantiate and contribute

override

public void override(K key,
                     V value)

Description copied from interface: MappedConfiguration

Overrides an existing contribution by its key.

Specified by:

override in interface MappedConfiguration<K,V>

Parameters:

key - unique id of value to override

value - new value, or null to remove the key entirely

overrideInstance

public void overrideInstance(K key,
                             Class<? extends V> clazz)

Description copied from interface: MappedConfiguration

Overrides an existing contribution with a new instance. When the value type is an interface and the class to be contributed is a local file, then a reloadable proxy for the value class will be created and contributed.

Specified by:

overrideInstance in interface MappedConfiguration<K,V>

Parameters:

key - unique id of value to override

clazz - class to instantiate as override
