Class RefineOperator

java.lang.Object

ca.mcscert.jpipe.operators.CompositionOperator

ca.mcscert.jpipe.operators.builtin.RefineOperator

public final class RefineOperator
extends CompositionOperator

Built-in refine composition operator.

Syntax:

justification result is refine(base, refinement) {
    hook: "base/elementId"
}

Semantics: the hook element (identified by model name and element id) from base and the conclusion of refinement are merged into a single SubConclusion named "hook". All other elements are kept with their source model name as id prefix (e.g. base:c, refinement:s).

protected MergeFunction	mergeFunction(List<JustificationModel<?>> sources, Map<String,String> arguments)	Returns the merge function to use for creating result elements from sources and arguments.
protected Set<String>	requiredArguments()	Declares which argument keys this operator requires.

Method Details

requiredArguments

protected Set<String> requiredArguments()

Description copied from class: CompositionOperator

Declares which argument keys this operator requires. The framework validates their presence at the start of CompositionOperator.apply(String, List, Map) and throws InvalidOperatorCallException listing any missing keys. Default: empty set (no required arguments).

Overrides:

createResultModel

protected Command createResultModel(String name,
 SourceLocation location,
 List<JustificationModel<?>> sources,
 Map<String,String> arguments)

Description copied from class: CompositionOperator

Returns the command that creates the result model (typically CreateJustification or CreateTemplate).

Specified by:

createResultModel in class CompositionOperator

Parameters:

location - the source location of the operator call; forwarded to the creation command so the result model appears in the symbol table.

sources - the source models being composed; provided so operators can choose the result model type (e.g. Template vs Justification) based on the source types.

equivalenceRelation

protected EquivalenceRelation equivalenceRelation(List<JustificationModel<?>> sources,
 Map<String,String> arguments)

Description copied from class: CompositionOperator

Returns the equivalence relation to use for partitioning elements from sources and arguments.

Specified by:

equivalenceRelation in class CompositionOperator

mergeFunction

protected MergeFunction mergeFunction(List<JustificationModel<?>> sources,
 Map<String,String> arguments)

Description copied from class: CompositionOperator

Returns the merge function to use for creating result elements from sources and arguments.

Specified by:
