Interface com.ibm.as400.access.AS400DataType
- public interface AS400DataType
- extends Cloneable, Serializable
The AS400DataType interface provides an interface for conversions between Java objects and byte arrays representing AS/400 data types.
-
clone()
- Creates a new AS400DataType object that is identical to the current instance.
-
getByteLength()
- Returns the byte length of the data type.
-
getDefaultValue()
- Returns a Java object representing the default value of the data type.
-
toBytes(Object)
- Converts the specified Java object to AS/400 format.
-
toBytes(Object, byte[])
- Converts the specified Java object into AS/400 format in the specified byte array.
-
toBytes(Object, byte[], int)
- Converts the specified Java object into AS/400 format in the specified byte array.
-
toObject(byte[])
- Converts the specified AS/400 data type to a Java object.
-
toObject(byte[], int)
- Converts the specified AS/400 data type to a Java object.
clone
public abstract Object clone()
- Creates a new AS400DataType object that is identical to the current instance.
- Returns:
- The new object.
- Overrides:
- clone in class Object
getByteLength
public abstract int getByteLength()
- Returns the byte length of the data type.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
getDefaultValue
public abstract Object getDefaultValue()
- Returns a Java object representing the default value of the data type.
- Returns:
- The Object of the corresponding data type.
toBytes
public abstract byte[] toBytes(Object javaValue)
- Converts the specified Java object to AS/400 format.
- Parameters:
- javaValue - The object corresponding to the data type. It must be an instance of the correct type.
- Returns:
- The AS/400 representation of the data type.
toBytes
public abstract int toBytes(Object javaValue,
byte as400Value[])
- Converts the specified Java object into AS/400 format in the specified byte array.
- Parameters:
- javaValue - The object corresponding to the data type. It must be an instance of the correct type.
- as400Value - The array to receive the data type in AS/400 format. There must be enough space to hold the AS/400 value.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
toBytes
public abstract int toBytes(Object javaValue,
byte as400Value[],
int offset)
- Converts the specified Java object into AS/400 format in the specified byte array.
- Parameters:
- javaValue - The object corresponding to the data type. It must be an instance of the correct type.
- as400Value - The array to receive the data type in AS/400 format. There must be enough space to hold the AS/400 value.
- offset - The offset into the byte array for the start of the AS/400 value. It must be greater than or equal to zero.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
toObject
public abstract Object toObject(byte as400Value[])
- Converts the specified AS/400 data type to a Java object.
- Parameters:
- as400Value - The array containing the data type in AS/400 format. The entire data type must be represented.
- Returns:
- The object corresponding to the data type.
toObject
public abstract Object toObject(byte as400Value[],
int offset)
- Converts the specified AS/400 data type to a Java object.
- Parameters:
- as400Value - The array containing the data type in AS/400 format. The entire data type must be represented.
- offset - The offset into the byte array for the start of the AS/400 value. It must be greater than or equal to zero.
- Returns:
- The object corresponding to the data type.
