Constructor Detail

ConstructorItem

public ConstructorItem(Constructor delegate,
                       ClassItem parent)
                throws InvalidDelegateException

Default contructor to create a new constructor item object.

Parameters:

delegate - the java.lang.reflect.Constructor actual meta item

Method Detail

toConstructors

public static Constructor[] toConstructors(ConstructorItem[] constructorItems)

Transforms a constructor items array into a constructors array containing the java.lang.reflect constructors wrapped by the constructor items.

Parameters:

constructorItems - the Constructor items

the actual Constructors in java.lang.reflect

getActualConstructor

public Constructor getActualConstructor()

Get the constructor represented by this constructor item.

Returns:

the actual constructor

getName

public String getName()

Description copied from class: MetaItem

This method gets the name of the meta item by delegating to the actual java.lang.reflect meta item.

Specified by:

getName in class MetaItem

Returns:

the item name

getType

public Class getType()

Description copied from class: MetaItemDelegate

This method gets the type of the meta item by delegating to the actual java.lang.reflect meta item.

Specified by:

getType in class MemberItem

Returns:

the item type

newInstance
