Class AbstractDeclaredStatement<A>

java.lang.Object

org.opendaylight.yangtools.yang.parser.rfc7950.stmt.AbstractDeclaredStatement<A>

All Implemented Interfaces:

DeclaredStatement<A>, ModelStatement<A>

Direct Known Subclasses:

AbstractDeclaredStatement.ArgumentToString, AbstractDeclaredStatement.WithQNameArgument, AbstractDeclaredStatement.WithRawArgument

@Beta
public abstract class AbstractDeclaredStatement<A>
extends Object
implements DeclaredStatement<A>

An abstract base class for DeclaredStatement implementations. This is a direct competition to AbstractDeclaredStatement, providing lower-footprint implementations.

Method Detail

getStatementSource

public StatementSource getStatementSource()

Description copied from interface: ModelStatement

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

Specified by:

getStatementSource in interface ModelStatement<A>

Returns:

statement source.

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
