Method Detail

getType

ImageView.ImageBindMapping.Type getType()

Returns:

The load type supported by this mapping.

toImage

Image toImage(java.lang.Object value)

Converts a value from the bind context to an image representation during a Component.load(Object) operation.

Parameters:

value - The value returned from the bound object.

Returns:

The image converted from the bound value.

toImageURL

java.net.URL toImageURL(java.lang.Object value)

Converts a value from the bind context to an image location during a Component.load(Object) operation.

Parameters:

value - The value returned from the bound object.

Returns:

The value converted to an image URL.

toImageName

java.lang.String toImageName(java.lang.Object value)

Converts a value from the bind context to an image resource name during a Component.load(Object) operation.

Parameters:

value - The value returned from the bound object.

Returns:

The value converted to an image name.

valueOf

java.lang.Object valueOf(Image image)

Converts an image to a value to be stored in the bind context during a Component.store(Object) operation.

Note: if the bind type is ImageView.ImageBindMapping.Type.URL or ImageView.ImageBindMapping.Type.NAME then this will likely entail also persisting the image itself somewhere else and returning the name/location of the stored image.

Parameters:

image - The image currently stored in the image view.

Returns:

The image converted to a value suitable for persistence in the bound object.
