Member Function Documentation

LookTypeBase * look::LookInteger::GetNewCopy ( void ) const [virtual]

Get a new copy. Virtual copy constructor, aka clone. Returns: A new copy of this. (You are responsible for deleting it). Reimplemented from look::LookTypeBase.

LookString look::LookInteger::GetOrdinalString ( void ) const

Convert to a ordinal string. Returns: Ordinal string, eg 1st, 2nd, 11th, 21st, 103rd, 1004th

LookString look::LookInteger::GetSpelledOrdinalString ( void ) const

Convert to a spelled ordinal string. This can only cope with 0-99 - used for LookDateTimeFormatter (so it can do "First of January"). If it is out of range, "Out of Range" is returned. Returns: Spelled ordinal string, eg First, Second, Eleventh, Twenty-first, Eightieth

LookString look::LookInteger::GetString ( int theWidth ) const

Conversion to a string given a width. Converts to a decimal string, fitted to theWidth. If theWidth is insufficient, '*' characters are returned. Leading zeroes are prepended if necessary to ensure the returned string is wide enough. Parameters: theWidth   Width of string Returns: Converted string. It will always be theWidth characters long.

LookString look::LookInteger::GetString ( void ) const

Conversion to a string. Converts to a decimal string

long look::LookInteger::GetTypeID ( void ) const [virtual]

Get Type ID. Pseudo-rtti, or isA. Returns: LookIntegerID Reimplemented from look::LookTypeBase.

bool look::LookInteger::Set ( const LookString & theString )

Convert from decimal string. Converts using strtol. Returns false in case of overflow or invalid characters. If invalid characters, itsValue is still set as best it can. Parameters: theString   The string Returns: true for success
