IOracleCustomType Interface methods are listed in Table 14-23.
Table 14-23 IOracleCustomType Interface Methods
| 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.
Declaration
// C# void FromCustomObject(OracleConnection con, IntPtr pUdt);
Parameters
con
An OracleConnection instance.
pUdt
An opaque pointer to the Oracle Object or Collection to be created.
Remarks
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.
Declaration
// C# void ToCustomObject (OracleConnection con, IntPtr pUdt);
Parameters
con
An OracleConnection instance.
pUdt
An opaque pointer to the Oracle UDT.
Remarks
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.
