| Interface Method | Description |
|---|---|
|
Returns the values that set the Oracle Object attributes |
|
|
Provides the Oracle Object with the attribute values to set on the custom type |
This interface method creates an Oracle Object or Collection by setting the attribute or element values respectively on the specified Oracle UDT.
// C# void FromCustomObject(OracleConnection con, IntPtr pUdt);
con
An OracleConnection instance.
pUdt
An opaque pointer to the Oracle Object or Collection to be created.
The FromCustomObject method is used to build an Oracle Object or Collection from a custom object by setting attribute or element values respectively through the OracleUdt.SetValue method.
The OracleUdt.SetValue method is invoked as follows:
Oracle Object Type
For a custom type that represents an Oracle Object Type, the OracleUdt.SetValue method must be invoked for each non-NULL attribute value that needs to be set.
Oracle Collection Type
For a custom type that represents an Oracle Collection Type, a single call to OracleUdt.SetValue method specifies the collection element values.
This interface initializes a custom object using the specified Oracle UDT.
// C# void ToCustomObject (OracleConnection con, IntPtr pUdt);
con
An OracleConnection instance.
pUdt
An opaque pointer to the Oracle UDT.
The ToCustomObject method is used to initialize a custom object from the specified Oracle Object or Collection by retrieving attribute or element values respectively through the OracleUdt.GetValue method.
The OracleUdt.GetValue method is invoked as follows:
Oracle Object Type
For a custom type that represents an Oracle Object Type, the OracleUdt.GetValue method must be invoked for each attribute value to be retrieved.
For a custom type that represents an Oracle Collection Type, a single call to OracleUdt.GetValue method retrieves the collection element values.
