AbstractConstraintEffectiveStatement

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

Method Detail

argument

public final A argument()

Description copied from interface: ModelStatement

Returns statement argument.

Specified by:

argument in interface ModelStatement<A>

Overrides:

argument in class DeclaredEffectiveStatementBase<A,D extends DeclaredStatement<A>>

Returns:

statement argument or null if statement does not have argument.

isCustomizedStatement

public final boolean isCustomizedStatement()

getModifier

public final ModifierKind getModifier()

getErrorAppTag

public final Optional<String> getErrorAppTag()

Description copied from interface: ConstraintMetaDefinition

Returns the value of the argument of YANG error-app-tag keyword.

Specified by:

getErrorAppTag in interface ConstraintMetaDefinition

Returns:

string with the application tag, or empty if it was not provided.

getErrorMessage

public final Optional<String> getErrorMessage()

Description copied from interface: ConstraintMetaDefinition

Returns the value of the argument of YANG error-message keyword.

Specified by:

getErrorMessage in interface ConstraintMetaDefinition

Returns:

string with the error message, or empty if it was not provided.

createConstraints

protected abstract A createConstraints(A 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
