OracleCustomTypeMappingAttribute Class

The OracleCustomTypeMappingAttribute class is used to mark a custom type factory class or struct with information that is used by ODP.NET when a custom type is used to represent an Oracle UDT.

Class Inheritance

System.Object

System.Attribute

System.OracleCustomTypeMappingAttribute

Declaration

// C#
[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct,  
   AllowMultiple=false, Inherited=true)]
public sealed class OracleCustomTypeMappingAttribute : Attribute

Remarks

The OracleCustomTypeMapping attribute must be specified on the custom type factory class to indicate the Oracle UDT that the corresponding custom type represents. The Oracle UDT may be specified in the form schema_name.type_name.

For each Oracle UDT that the application uses, there must be a unique custom type factory, as follows:

If the OracleCustomTypeMappingAttribute is not specified, then custom type mappings must be specified through an XML configuration file, for example, app.config for Windows applications or the web.config for web applications, and the machine.config

Thread Safety

All public static methods are thread-safe, although instance methods do not guarantee thread safety.

Requirements

Namespace: Oracle.DataAccess.Types

Assembly: Oracle.DataAccess.dll

ODP.NET Version: ODP.NET for .NET Framework 2.0 or ODP.NET for .NET Framework 4
