All Implemented Interfaces:

Serializable, Comparable<IsoType>

public enum IsoType
extends Enum<IsoType>

Defines the possible values types that can be used in the fields. Some types required the length of the value to be specified (NUMERIC and ALPHA). Other types have a fixed length, like dates and times. Other types do not require a length to be specified, like LLVAR and LLLVAR.

Enum Constant Summary

ALPHA
A fixed-length alphanumeric value.

AMOUNT
An amount, expressed in cents with a fixed length of 12.

BINARY
Similar to ALPHA but holds byte arrays instead of strings.

DATE_EXP
A date in format yyMM

DATE10
A date in format MMddHHmmss

DATE4
A date in format MMdd

LLBIN
Similar to LLVAR but holds byte arrays instead of strings.

LLLBIN
Similar to LLLVAR but holds byte arrays instead of strings.

LLLVAR
A variable length alphanumeric value with a 3-digit header length.

LLVAR
A variable length alphanumeric value with a 2-digit header length.

NUMERIC
A fixed-length numeric value.

TIME
Time of day in format HHmmss

Method Summary

IsoValue<Object>	call(Object val)
IsoValue<Object>	call(Object val, int len)
String	format(BigDecimal value, int length) Formats the BigDecimal as an AMOUNT, NUMERIC, or a String.
String	format(Date value) Formats a Date if the receiver is DATE10, DATE4, DATE_EXP or TIME; throws an exception otherwise.
String	format(long value, int length) Formats the integer value as a NUMERIC, an AMOUNT, or a String.
String	format(String value, int length) Formats the string to the given length (length is only useful if type is ALPHA, NUMERIC or BINARY).
int	getLength() Returns the length of the type if it's always fixed, or 0 if it's variable.
boolean	needsLength() Returns true if the type needs a specified length.
IsoValue<Object>	value(Object val)
IsoValue<Object>	value(Object val, int len)
static IsoType	valueOf(String name) Returns the enum constant of this type with the specified name.
static IsoType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static IsoType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IsoType c : IsoType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IsoType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

needsLength

public boolean needsLength()

Returns true if the type needs a specified length.

getLength

public int getLength()

Returns the length of the type if it's always fixed, or 0 if it's variable.

format

public String format(Date value)

Formats a Date if the receiver is DATE10, DATE4, DATE_EXP or TIME; throws an exception otherwise.

format

public String format(String value,
                     int length)

Formats the string to the given length (length is only useful if type is ALPHA, NUMERIC or BINARY).

format

public String format(long value,
                     int length)

Formats the integer value as a NUMERIC, an AMOUNT, or a String.

format

public String format(BigDecimal value,
                     int length)

Formats the BigDecimal as an AMOUNT, NUMERIC, or a String.

value

public IsoValue<Object> value(Object val,
                              int len)

value

public IsoValue<Object> value(Object val)

call

public IsoValue<Object> call(Object val,
                             int len)

call

public IsoValue<Object> call(Object val)
