getSupportedWriteAccess

public static EnumSet<AttributeWriteMask.Options> getSupportedWriteAccess(UnsignedInteger... attributeIds)

Return an new EnumSet of AttributeWriteMask.Options for the given attribute ids.

hasAccessToAttribute

public static boolean hasAccessToAttribute(AttributeWriteMask mask,
                                           UnsignedInteger attributeId)

Returns true if the given mask indicates that the given Attribute Id is writeable.

isValid

public static boolean isValid(NodeClass nodeClass,
                              UnsignedInteger attributeId)

Checks if a given NodeClass contains the given AttributeId.

Parameters:

nodeClass - the given NodeClass

attributeId - the given AttributeId, typically via Attributes constants.

Returns:

true if valid

isValid

public static boolean isValid(UnsignedInteger attributeId)

Returns true if the given Attribute Id is a known Attribute Id.

toString
