Java compact3 javax.sql.rowset.serial Class SerialStruct（JDK8）

Constructor Detail

• SerialStruct

  public SerialStruct(Struct in,
                      Map<String,Class<?>> map)
               throws SerialException

  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.

  Parameters:

  in - an instance of Struct

  map - a java.util.Map object in which each entry consists of 1) a String object giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped

  Throws:

  SerialException - if an error occurs

• SerialStruct

  public SerialStruct(SQLData in,
                      Map<String,Class<?>> map)
               throws SerialException

  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. The type map gives the SQL type and the class to which it is mapped. The SQLData object defines the class to which the SQL type will be mapped.

  Parameters:

  in - an instance of the SQLData class that defines the mapping of the SQL structured type to one or more objects in the Java programming language

  map - a java.util.Map object in which each entry consists of 1) a String object giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped

  Throws:

  SerialException - if an error occurs

Method Detail

• getSQLTypeName

  public String getSQLTypeName()
                        throws SerialException

  Retrieves the SQL type name for this SerialStruct object. This is the name used in the SQL definition of the structured type

  Specified by:

  getSQLTypeName in interface Struct

  Returns:

  a String object representing the SQL type name for the SQL structured type that this SerialStruct object represents

  Throws:

  SerialException - if an error occurs

• getAttributes

  public Object[] getAttributes()
                         throws SerialException

  Retrieves an array of Object values containing the attributes of the SQL structured type that this SerialStruct object represents.

  Specified by:

  getAttributes in interface Struct

  Returns:

  an array of Object values, with each element being an attribute of the SQL structured type that this SerialStruct object represents

  Throws:

  SerialException - if an error occurs

• getAttributes

  public Object[] getAttributes(Map<String,Class<?>> map)
                         throws SerialException

  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.

  Specified by:

  getAttributes in interface Struct

  Parameters:

  map - a java.util.Map object in which each entry consists of 1) a String object giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped

  Returns:

  an array of Object values, with each element being an attribute of the SQL structured type that this SerialStruct object represents

  Throws:

  SerialException - if an error occurs

• equals

  public boolean equals(Object obj)

  Compares this SerialStruct to the specified object. The result is true if and only if the argument is not null and is a SerialStruct object whose attributes are identical to this object's attributes

  Overrides:

  equals in class Object

  Parameters:

  obj - The object to compare this SerialStruct against

  Returns:

  true if the given object represents a SerialStruct equivalent to this SerialStruct, false otherwise

  Object.hashCode(), HashMap

• hashCode

  public int hashCode()

  Returns a hash code for this SerialStruct. The hash code for a SerialStruct object is computed using the hash codes of the attributes of the SerialStruct object and its SQLTypeName

  Overrides:

  hashCode in class Object

  Returns:

  a hash code value for this object.

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• clone

  public Object clone()

  Returns a clone of this SerialStruct. The copy will contain a reference to a clone of the underlying attribs array, not a reference to the original underlying attribs array of this SerialStruct object.

  Overrides:

  clone in class Object

  Returns:

  a clone of this SerialStruct
