Method Summary

void	destroy() Closes down all parts of DWR in a timely way, stops threads, and performs tidy-up.
<T> T	getBean(java.lang.Class<T> type) Get the contained instance of a bean of a given type
java.lang.Object	getBean(java.lang.String id) Get the contained instance of a bean/setting of a given name.
java.util.Collection<java.lang.String>	getBeanNames() Get a list of all the available beans.
void	initializeBean(java.lang.Object object) Sometimes we need to take a bean not created by the container, and inject it with the data that it would contain if it was created by the container.
<T> T	newInstance(java.lang.Class<T> type) Sometimes we need to create a bean as a one-off object and have it injected with settings by the container.

Method Detail

getBean

java.lang.Object getBean(java.lang.String id)

Get the contained instance of a bean/setting of a given name.

Parameters:

id - The type to get an instance of

Returns:

The object of the given type, or null if the object does not exist

getBean

<T> T getBean(java.lang.Class<T> type)

Get the contained instance of a bean of a given type

Parameters:

type - The type to get an instance of

Returns:

The object of the given type, or null if the object does not exist

getBeanNames

java.util.Collection<java.lang.String> getBeanNames()

Get a list of all the available beans. Implementation of this method is optional so it is valid for this method to return an empty collection, but to return Objects when queried directly using getBean(String). This method should only be used for debugging purposes.

Returns:

A collection containing all the available bean names.

destroy

void destroy()

Closes down all parts of DWR in a timely way, stops threads, and performs tidy-up.

newInstance

<T> T newInstance(java.lang.Class<T> type)
              throws java.lang.InstantiationException,
                     java.lang.IllegalAccessException

Sometimes we need to create a bean as a one-off object and have it injected with settings by the container. This does not make the object part of the container.

Parameters:

type - The type to get an instance of

Throws:

java.lang.InstantiationException

java.lang.IllegalAccessException

initializeBean

void initializeBean(java.lang.Object object)

Sometimes we need to take a bean not created by the container, and inject it with the data that it would contain if it was created by the container. This does not make the object part of the container.

Parameters:

object - The object to inject.
