Constructor Detail

FieldParseInfo

public FieldParseInfo(IsoType t,
                      int len)

Creates a new instance that parses a value of the specified type, with the specified length. The length is only useful for ALPHA and NUMERIC types.

Parameters:

t - The ISO type to be parsed.

len - The length of the data to be read (useful only for ALPHA and NUMERIC types).

getCharacterEncoding

public String getCharacterEncoding()

getLength

public int getLength()

Returns the specified length for the data to be parsed.

getType

public IsoType getType()

Returns the data type for the data to be parsed.
