AbstractDeclaredStatement

public AbstractDeclaredStatement()

Method Detail

statementOrigin

public StatementOrigin statementOrigin()

Description copied from interface: ModelStatement

Returns StatementOrigin, which denotes if statement was explicitly declared in original model or inferred during semantic processing of model.

Specified by:

statementOrigin in interface ModelStatement<A>

Returns:

statement origin.

declaredSubstatements

public Collection<? extends DeclaredStatement<?>> declaredSubstatements()

Description copied from interface: DeclaredStatement

Returns collection of explicitly declared child statements, while preserving its original ordering from original source.

Specified by:

declaredSubstatements in interface DeclaredStatement<A>

Returns:

Collection of statements, which were explicitly declared in source of model.

unmaskList

protected static final @NonNull ImmutableList<? extends DeclaredStatement<?>> unmaskList(@NonNull Object masked)

Utility method for recovering singleton lists squashed by maskList(ImmutableList).

Parameters:

masked - list to unmask

Returns:

Unmasked list

Throws:

NullPointerException - if masked is null

ClassCastException - if masked object does not match DeclaredStatement

maskList

protected static final @NonNull Object maskList(ImmutableList<?> list)

Utility method for squashing singleton lists into single objects. This is a CPU/mem trade-off, which we are usually willing to make: for the cost of an instanceof check we can save one object and re-create it when needed. The inverse operation is #unmaskSubstatements(Object)}.

Parameters:

list - list to mask

Returns:

Masked list

Throws:

NullPointerException - if list is null

unmaskList

protected static final <T> @NonNull ImmutableList<T> unmaskList(@NonNull Object masked,
                                                                @NonNull Class<T> type)

Utility method for recovering singleton lists squashed by maskList(ImmutableList).

Parameters:

masked - list to unmask

Returns:

Unmasked list

Throws:

NullPointerException - if any argument is null

ClassCastException - if masked object does not match expected class

maskSet

protected static final @NonNull Object maskSet(ImmutableSet<?> set)

unmaskSet

protected static final <T> @NonNull ImmutableSet<T> unmaskSet(@NonNull Object masked,
                                                              @NonNull Class<T> type)
