isValidFor

public boolean isValidFor(LayerContext ctx)

Description copied from class: LayerType

Tests if this type can create layers for the given application provided context. Note that some applications may provide their context through the extension object interface (see ExtensibleObject.getExtension(Class)).

Specified by:

isValidFor in class LayerType

Parameters:

ctx - An application-dependent layer context.

Returns:

true if the type is valid with respect to the given context.

createLayerConfig

public PropertySet createLayerConfig(LayerContext ctx)

Description copied from class: LayerType

Creates a default configuration instance for the type of layers this type can create. After a default configuration has been created it is usually modified to specify a layer's construction parameters, e.g. for an image layer this could be the file path to the image file. Then, an application will pass the configuration to the LayerType.createLayer(com.bc.ceres.glayer.LayerContext, com.bc.ceres.binding.PropertySet) method in order to create a new layer instance.

Specified by:

createLayerConfig in class LayerType

Parameters:

ctx - An application provided context, may be null. The parameter may be ignored by many layer types.

Returns:

A new layer (default) configuration.

createLayer

public Layer createLayer(LayerContext ctx,
                         PropertySet configuration)

Description copied from class: LayerType

Creates a layer instance for the given application provided context and the given layer configuration. The configuration may contain both, inmutable construction parameters passed to specific layer constructor as well as mutable layer properties.

Specified by:

createLayer in class LayerType

Parameters:

ctx - An application provided context, may be null. The parameter may be ignored by many layer types.

configuration - The layer configuration.

Returns:

A new layer instance.
