Class BinaryDataType

java.lang.Object
  javax.rad.model.datatype.DataType
      javax.rad.model.datatype.BinaryDataType

All Implemented Interfaces:

Serializable, Cloneable, IDataType

public class BinaryDataType
extends DataType

A BinaryDataType is the data type class of a binary ColumnDefinition.

See Also:

Serialized Form

Field Summary

static int

TYPE_IDENTIFIER the type identifier.

Constructor Summary

BinaryDataType()
Constructs a BinaryDataType with the maximum Integer size.

BinaryDataType(ICellEditor pCellEditor)
Constructs a BinaryDataType with the maximum Integer size and the given cell editor.

BinaryDataType(int pSize)
Constructs a BinaryDataType with the given Integer size.

BinaryDataType(int pSize, ICellEditor pCellEditor)
Constructs a BinaryDataType with the given Integer size and the given cell editor.

Method Summary

BinaryDataType	clone() Clone an IDataType.
int	compareTo(Object pObject1, Object pObject2) Compares IDataType objects in the rules of the Comparable interface. Implementations need to take care about to null objects are equal.
Object	convertAndCheckToTypeClass(Object pObject) Converts the oObject to an Object which is an instance of the class which is handled by IDataType.
String	convertToString(Object pObject) Converts the oObject into a String which represents the Object.
Object	convertToTypeClass(Object pObject) Converts the oObject to an Object which is an instance of the class which is handled by IDataType.
static byte[]	getContent(Object pBinaryObject) Get's the content to the given object.
Class	getTypeClass() Returns the class of the Object's handled by IDataType.
int	getTypeIdentifier() Gets the data type identifier.
Object	prepareValue(Object pObject) Prepares the given value. This is used for preparing values for client-side usage and occurs before the client side receives the value for the first time. If there is nothing to be done, the same object as passed in needs to be returned.

Constructor Detail

BinaryDataType

public BinaryDataType()

Constructs a BinaryDataType with the maximum Integer size.

BinaryDataType

public BinaryDataType(int pSize)

Constructs a BinaryDataType with the given Integer size.

Parameters:

pSize - the size

BinaryDataType

public BinaryDataType(ICellEditor pCellEditor)

Constructs a BinaryDataType with the maximum Integer size and the given cell editor.

Parameters:

pCellEditor - the cell editor

BinaryDataType

public BinaryDataType(int pSize,
                      ICellEditor pCellEditor)

Constructs a BinaryDataType with the given Integer size and the given cell editor.

Method Detail

getTypeIdentifier

public int getTypeIdentifier()

Gets the data type identifier.

Returns:

a unique type identifier

getTypeClass

public Class getTypeClass()

Returns the class of the Object's handled by IDataType.

Returns:

the class of the Object's handled by IDataType.

convertAndCheckToTypeClass

public Object convertAndCheckToTypeClass(Object pObject)
                                  throws ModelException

Converts the oObject to an Object which is an instance of the class which is handled by IDataType. The resulting Object is also checked against the type attributes like size, precision,...

Parameters:

pObject - the source Object to convert

Returns:

the converted Object that is instance of the class which is handled by IDataType.

Throws:

ModelException - if the Object is outside the limits of the DataType attributes

convertToString

public String convertToString(Object pObject)

Converts the oObject into a String which represents the Object.

Parameters:

pObject - the source Object to convert

Returns:

the String representation of the source Object

convertToTypeClass

public Object convertToTypeClass(Object pObject)
                          throws ModelException

Converts the oObject to an Object which is an instance of the class which is handled by IDataType.

Parameters:

pObject - the source Object to convert

Returns:

the converted Object that is instance of the class which is handled by IDataType.

Throws:

ModelException - if the class/type of oObject is not supported

compareTo

public int compareTo(Object pObject1,
                     Object pObject2)

Compares IDataType objects in the rules of the Comparable interface. Implementations need to take care about to null objects are equal.

Specified by:

compareTo in interface IDataType

Overrides:

compareTo in class DataType

Parameters:

pObject1 - a getTypeClass() object of one IDataType

pObject2 - a getTypeClass() object of one IDataType

Returns:

-1 if pObject1 is smaller, 0 if equal and +1 if it is greater then pObject2

clone

public BinaryDataType clone()

Clone an IDataType.

Specified by:

clone in interface IDataType

Overrides:

clone in class DataType

Returns:

a clone of this IDataType

See Also:

Object.clone()

prepareValue

public Object prepareValue(Object pObject)
                    throws ModelException

Prepares the given value.

This is used for preparing values for client-side usage and occurs before the client side receives the value for the first time.

If there is nothing to be done, the same object as passed in needs to be returned.

Specified by:

prepareValue in interface IDataType

Overrides:

prepareValue in class DataType

Parameters:

pObject - the object to prepare.

Returns:

the prepared object. If there is nothing to do, the same object.

Throws:

ModelException - if the preparation failed.

getContent

                               throws IOException

Get's the content to the given object.

Parameters:

pBinaryObject - the object

Returns:

the byte[]

Throws:

IOException - if it fails.
