Class AbstractDeclaredEffectiveStatement.DefaultArgument<A,D extends DeclaredStatement<A>>

java.lang.Object

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

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

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

org.opendaylight.yangtools.yang.parser.rfc7950.stmt.AbstractDeclaredEffectiveStatement.DefaultArgument<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:

EffectiveStatement<A,D>, ModelStatement<A>

Direct Known Subclasses:

AbstractDeclaredEffectiveStatement.DefaultArgument.WithSubstatements

Enclosing class:

AbstractDeclaredEffectiveStatement<A,D extends DeclaredStatement<A>>

public abstract static class AbstractDeclaredEffectiveStatement.DefaultArgument<A,D extends DeclaredStatement<A>>
extends AbstractDeclaredEffectiveStatement.Default<A,D>

An extra building block on top of AbstractDeclaredEffectiveStatement.Default, which is wiring argument() to the declared statement. This is mostly useful for arguments that are not subject to inference transformation -- for example Strings in description, etc. This explicitly is not true of statements which underwent namespace binding via uses or similar.

Method Detail

argument

public final A argument()

Description copied from interface: ModelStatement

Returns statement argument.

Returns:

statement argument or null if statement does not have argument.

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
