Method Details

createWebResource

static ComponentResource<byte[]> createWebResource(String name,
 byte[] data)

Creates a static web resource.

Parameters:

name - name

data - content

Returns:

static web resource

getResources

static Iterable<ComponentResource<?>> getResources(Class<?> targetClass)

Gets all resources definitions tied to an implementation class

Parameters:

targetClass - class to check

Returns:

resource definitions

needsAuthentication

public boolean needsAuthentication()

Description copied from interface: IuResource

Determines whether or not the resource should be authenticated before handing off to a managed application.

Specified by:

needsAuthentication in interface IuResource<T>

Returns:

true if the resource requires authentication; else false

shared

public boolean shared()

Description copied from interface: IuResource

Determines whether or not the resource is shared.

Specified by:

shared in interface IuResource<T>

Returns:

true if the resource is shared; else false

priority

public int priority()

Description copied from interface: IuResource

Indicates the initialization priority.

Specified by:

priority in interface IuResource<T>

Returns:

initialization priority

name

public String name()

Description copied from interface: IuResource

Gets the resource name.

Specified by:

name in interface IuResource<T>

Returns:

resource name

type

public IuType<?,T> type()

Description copied from interface: IuResource

Gets the resource type

Specified by:

type in interface IuResource<T>

Returns:

resource type

factory

public Supplier<?> factory()

Description copied from interface: IuResource

Gets the factory to be used for creating new instances.

By default, returns a Supplier that:

• Returns IuType.autoboxDefault() if the resource type is an immutable single-value
• Invokes IuExecutable.exec(Object...) on an an internally managed implementation class or InvocationHandler suitable for representing the resource

Specified by:

factory in interface IuResource<T>

Returns:

factory that supplies new instance of the resource, or an InvocationHandler for backing a Proxy.

factory

public void factory(Supplier<?> factory)

Description copied from interface: IuResource

Provides a factory to use for creating new instances of the resource.

The factory may return:

• A direct instance of the resource class.
• A instance of a class that implements the resource interface
• An InvocationHandler to back a Proxy for the resource interface

To selective override default behavior, call IuResource.factory() first to get a reference to the default factory.

Specified by:

factory in interface IuResource<T>

Parameters:

factory - resource implementation factory.

get

public T get()

Description copied from interface: IuResource

Gets the resource value.

Provides a new or immutable instance when IuResource.shared() returns false; may provide the same instance on subsequent calls when IuResource.shared() returns true.

Specified by:

get in interface IuResource<T>

Specified by:

get in interface Supplier<T>

toString

public String toString()

Overrides:

toString in class Object
