Method Detail

initialiseChain

public static ResourceTransformationContext initialiseChain(ResourceTransformationContext context,
                                                            OperationTransformerRegistry.PlaceholderResolver placeholderResolver)

Call when starting a new chain of model versions. This will copy the ResourceTransformationContext instance, using the extra resolver to resolve the children of the placeholder resource.

Parameters:

context - the context to copy. It should be at a chained placeholder

placeholderResolver - the extra resolver to use to resolve the placeholder's children for the first model version delta in the chain

Returns:

a new ResourceTransformationContext instance using the extra resolver

nextInChainResource

public static ResourceTransformationContext nextInChainResource(ResourceTransformationContext context,
                                                                OperationTransformerRegistry.PlaceholderResolver placeholderResolver)

Call when transforming a new model version delta for a resource. This will copy the ResourceTransformationContext instance, using the extra resolver to resolve the children of the placeholder resource.

Parameters:

context - the context to copy. It should be at a chained placeholder

placeholderResolver - the extra resolver to use to resolve the placeholder's children for the model version delta we are transforming

Returns:

a new ResourceTransformationContext instance using the extra resolver

nextInChainOperation

public static ResourceTransformationContext nextInChainOperation(ResourceTransformationContext context,
                                                                 OperationTransformerRegistry.PlaceholderResolver placeholderResolver)

Call when transforming a new model version delta for an operation. This will copy the ResourceTransformationContext instance, using the extra resolver to resolve the children of the placeholder resource.

Parameters:

context - the context to copy. It should be at a chained placeholder

placeholderResolver - the extra resolver to use to resolve the placeholder's children for the model version delta we are transforming

Returns:

a new ResourceTransformationContext instance using the extra resolver

transformAddress

public static PathAddress transformAddress(PathAddress original,
                                           TransformationTarget target)

Transform a path address.

Parameters:

original - the path address to be transformed

target - the transformation target

Returns:

the transformed path address
