Method Detail

setStringUtil

@Inject
public void setStringUtil(StringUtil stringUtil)

Parameters:

stringUtil - is the StringUtil to Inject.

setCollectionReflectionUtil

@Inject
public void setCollectionReflectionUtil(CollectionReflectionUtil collectionReflectionUtil)

Parameters:

collectionReflectionUtil - is the CollectionReflectionUtil to Inject.

doInitialize

protected void doInitialize()

Description copied from class: AbstractComponent

This method performs the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialize().

Overrides:

doInitialize in class AbstractLoggableComponent

doInitialized

protected void doInitialized()

Description copied from class: AbstractComponent

This method is invoked at the end of the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time after AbstractComponent.doInitialize() is completed and initialization-state has changed to initialized.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialized().

Overrides:

doInitialized in class AbstractComponent

getInstance

public static JsonUtil getInstance()

This method gets the singleton instance of this JsonUtilImpl.
ATTENTION:
Please read Cdi.GET_INSTANCE before using.

Returns:

the singleton instance.

read

public <T> T read(javax.json.stream.JsonParser json,
                  GenericType<T> type,
                  javax.json.stream.JsonParser.Event e)

Specified by:

read in interface JsonUtil

Type Parameters:

T - the generic type of the object to parse.

Parameters:

json - the JsonParser.

type - the GenericType of the requested object to parse.

e - the current JsonParser.Event.

Returns:

the parsed value.

readEnum

public <E extends Enum<E>> E readEnum(javax.json.stream.JsonParser json,
                                      Class<E> enumType)
                               throws IllegalCaseException

Specified by:

readEnum in interface JsonUtil

Type Parameters:

E - the generic type of the Enum to parse.

Parameters:

json - the JsonParser.

enumType - the Class reflecting the Enum to parse.

Returns:

the parsed Enum constant.

Throws:

IllegalCaseException - if no such Enum constant exists.

readCollection

public <C extends Collection<?>> C readCollection(javax.json.stream.JsonParser json,
                                                  GenericType<C> type)

Specified by:

readCollection in interface JsonUtil

Type Parameters:

                               Collection<E> collection,
                               GenericType<E> type)

Specified by:

readCollection in interface JsonUtil

Type Parameters:

E - the generic type of the elements in the Collection.

Parameters:

json - the JsonParser.

collection - the Collection where to add the elements parsed from JSON.

type - the GenericType of the elements in the Collection.

readMap

public <M extends Map<?,?>> M readMap(javax.json.stream.JsonParser json,
                                      GenericType<M> type)

Specified by:

readMap in interface JsonUtil
