public class SerialStruct extends Object implements Struct, Serializable, Cloneable
In addition, the structured type is custom mapped to a class in the Java programming language if there is such a mapping, as are its attributes, if appropriate.
The SerialStruct
class provides a constructor for creating an instance from a Struct
object, a method for retrieving the SQL type name of the SQL structured type in the database, and methods for retrieving its attribute values.
Constructor | Description |
---|---|
SerialStruct |
Constructs a SerialStruct object from the given SQLData object, using the given type map to custom map it to a class in the Java programming language. |
SerialStruct |
Constructs a SerialStruct object from the given Struct object, using the given java.util.Map object for custom mapping the SQL structured type or any of its attributes that are SQL structured types. |
Modifier and Type | Method | Description |
---|---|---|
Object |
clone() |
Returns a clone of this SerialStruct . |
boolean |
equals |
Compares this SerialStruct to the specified object. |
Object[] |
getAttributes() |
Retrieves an array of Object values containing the attributes of the SQL structured type that this SerialStruct object represents. |
Object[] |
getAttributes |
Retrieves the attributes for the SQL structured type that this SerialStruct represents as an array of Object values, using the given type map for custom mapping if appropriate. |
String |
