org.opendaylight.yangtools.yang.parser.rfc7950.stmt.EffectiveStatementBase<A,D>

Type Parameters:

A - Argument type (Void if statement does not have argument.)

D - Class representing declared version of this statement.

All Implemented Interfaces:

Constructor Detail

EffectiveStatementBase

protected EffectiveStatementBase(StmtContext<A,D,?> ctx)

Constructor.

Parameters:

ctx - context of statement.

Method Detail

initSubstatements

protected Collection<? extends EffectiveStatement<?,?>> initSubstatements(Collection<? extends StmtContext<?,?,?>> substatementsInit)

Create a set of substatements. This method is split out so it can be overridden in ExtensionEffectiveStatementImpl to leak a not-fully-initialized instance.

Parameters:

substatementsInit - proposed substatements

Returns:

Filtered substatements

effectiveSubstatements

public final Collection<? extends EffectiveStatement<?,?>> effectiveSubstatements()

Description copied from interface: EffectiveStatement

Returns a collection of all effective substatements.

Specified by:

effectiveSubstatements in interface EffectiveStatement<A,D extends DeclaredStatement<A>>

Overrides:

effectiveSubstatements in class AbstractEffectiveStatement<A,D extends DeclaredStatement<A>>

Returns:

collection of all effective substatements.

allSubstatementsOfType

public final <T> Collection<T> allSubstatementsOfType(Class<T> type)

firstSubstatementOfType

protected final <T> @Nullable T firstSubstatementOfType(Class<T> type)

firstSubstatementOfType

protected final <R> R firstSubstatementOfType(Class<?> type,
                                              Class<R> returnType)

firstEffectiveSubstatementOfType

protected final EffectiveStatement<?,?> firstEffectiveSubstatementOfType(Class<?> type)

firstSchemaNode

protected final <S extends SchemaNode> S firstSchemaNode(Class<S> type)

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<? extends T> unmaskSet(@NonNull Object masked,
                                                                        @NonNull Class<T> type)
