Method Detail

getDataTypeDefinition

DataTypeDefinition getDataTypeDefinition()

Get the DataTypeDefinition Attribute value. Note! this Attribute was added in UA 1.04, earlier servers do not support this, in which case this method returns null. Additionally this Attribute is only supported on Enumeration, Structure and sub-types of UInteger types defining OptionSet-like semantics.

Per specification 1.04 Part 3, for Enumeration, UInteger sub-types having OptionSet semantics and subtypes of the OptionSet Structure this should return EnumDefinition. For other Structure types StructureDefinition should be returned.

getJavaClass

default Class<?> getJavaClass()

Returns a Java class that is used to map this OPC UA type. For example, Integer is used to map the OPC UA Int32 DataType. This is based on the UaDataTypeSpecification for the type, which is searched from EncoderContext.
