Package software.amazon.smithy.build.transforms

Class Apply

java.lang.Object

software.amazon.smithy.build.transforms.ConfigurableProjectionTransformer<T>

software.amazon.smithy.build.transforms.Apply

All Implemented Interfaces:

ProjectionTransformer

public final class Apply
extends ConfigurableProjectionTransformer<T>

Recursively applies transforms of other projections.

Note: this transform is special cased and not created using a normal factory. This is because this transformer needs to recursively transform models based on projections, and no other transform needs this functionality. We could *maybe* address this later if we really care that much.

Constructor Detail

Apply

public Apply(Apply.ApplyCallback applyCallback)

Sets the function used to apply projections.

Parameters:

applyCallback - Takes the projection name, model, and returns the updated model.

Method Detail

getConfigType

public java.lang.Class<Apply.Config> getConfigType()

Description copied from class: ConfigurableProjectionTransformer

Gets the configuration class type.

The referenced configType class must be a public POJO with a public, zero-arg constructor, getters, and setters. If the POJO has a public static fromNode method, it will be invoked and is expected to deserialize the Node. If the POJO has a public static builder method, it will be invoked, setters will be called on the builder POJO, and finally the result of calling the build method is used as the configuration type. Finally, the deserializer will attempt to create the type and call setters on the instantiated object that correspond to property names (either named "set" + property name, or just property name).

Specified by:

getConfigType in class ConfigurableProjectionTransformer<Apply.Config>

Returns:

Returns the configuration class (a POJO with setters/getters).

getName

public java.lang.String getName()

Description copied from interface: ProjectionTransformer

Gets the name of the transformer.

Returns:

Returns the name (e.g., "traits").

transformWithConfig

protected Model transformWithConfig(TransformContext context,
                                    Apply.Config config)

Description copied from class: ConfigurableProjectionTransformer

Executes the transform using the deserialized configuration object.

Specified by:

transformWithConfig in class ConfigurableProjectionTransformer<Apply.Config>

Parameters:

context - Transform context.

config - Deserialized configuration object.

Returns:

Returns the transformed model.

transform

public final Model transform(TransformContext context)

Description copied from interface: ProjectionTransformer

Transforms the given model using the provided TransformContext.

Specified by:

transform in interface ProjectionTransformer

Overrides:

transform in class ConfigurableProjectionTransformer<T>

Parameters:

context - Transformation context.

Returns:

Returns the created transformer.
