All Implemented Interfaces:

VariableLengthFieldDescription, Serializable

public class DBCSEitherFieldDescription
extends FieldDescription
implements VariableLengthFieldDescription, Serializable

The DBCSEitherFieldDescription class represents the description of the data in a DBCS-either field. It allows:

• The user to describe a DBCS-either field to the RecordFormat object.
• The RecordFormat object to describe a DBCS-either field to the user.

Constructor Detail

DBCSEitherFieldDescription

public DBCSEitherFieldDescription()

Constructs a DBCSEitherFieldDescription object.

DBCSEitherFieldDescription

public DBCSEitherFieldDescription(AS400Text dataType,
                                  String name)

Constructs a DBCSEitherFieldDescription object. It uses the specified data type and name of the field. The length of the field will be the length specified on the AS400Text object.

Parameters:

dataType - Describes the field and provides the conversion capability for the contents of the field.

name - The name of the field.

DBCSEitherFieldDescription

public DBCSEitherFieldDescription(AS400Text dataType,
                                  String name,
                                  String ddsName)

Constructs a DBCSEitherFieldDescription object. It uses the specified data type, name, and DDS name of the field. The length of the field will be the length specified on the AS400Text object.

Parameters:

dataType - Describes the field and provides the conversion capability for the contents of the field.

name - The name of the field.

ddsName - The DDS name of this field. This is the name of the field as it would appear in a DDS description of the field. The length of ddsName must be 10 characters or less.

Method Detail

getCCSID

public String getCCSID()

Returns the value specified for the CCSID keyword for this field.

Returns:

The value specified for the CCSID keyword for this field. If CCSID was not specified for this field, an empty string is returned.

getVARLEN

public int getVARLEN()

Returns the value specified for the VARLEN keyword for this field.

Returns:

The value specified for VARLEN for this field. If VARLEN was not specified for this field, 0 is returned.

isVariableLength

public boolean isVariableLength()

Indicates if the field is a variable-length field.

Specified by:

isVariableLength in interface VariableLengthFieldDescription

Returns:

true if the field is a variable-length field; false otherwise.

setCCSID

public void setCCSID(String ccsid)

Sets the value for the CCSID keyword for this field.

Parameters:

ccsid - The value for the CCSID keyword for this field.

setDataType

public void setDataType(AS400Text dataType)

Sets the AS400DataType object describing this field.

Parameters:

dataType - The AS400DataType that describes this field. The dataType cannot be null.

setDFT

public void setDFT(String defaultValue)

Sets the value for the DFT keyword for this field.

Parameters:

defaultValue - The default value for this field. The defaultValue cannot be null. To set a default value of *NULL, use the setDFTNull() method.

setDFTNull

public void setDFTNull()

Sets the value for the DFT keyword to be *NULL for this field. Calling this method will replace the DFT keyword that was previously set on a call to setDFT(). Note: This field must also have its ALWNULL keyword set to true to prevent DDS errors.

setVariableLength

public void setVariableLength(boolean value)

Sets the value that indicates if the field is a variable-length field.

Specified by:

setVariableLength in interface VariableLengthFieldDescription

Parameters:

value - true if the field is a variable-length field; false otherwise.

setVARLEN

public void setVARLEN(int varLen)

Sets the value to specify for the VARLEN keyword for this field.

Parameters:

varLen - The value to specify for the VARLEN keyword for this field. The varLen cannot be less than zero.
