Method Detail

getUnitValue

public static ParsedUnit getUnitValue(java.lang.String inputStr)

Parses a substring containing that *starts* with the definition of a quantity. So if the command is [paraindent:36pt], this routine would be passed 36pt] and would return a structure containing the value 36 the unit-type (enum) POINT, and the length of characters gobbled; 3. This method correctly handles macros in the string.

Parameters:

inputStr - string containing quantity and unit abbreviation

Returns:

a ParsedUnit instance containing value and type, or error type & error message

parseUnitType

public static PlatyConst.unit parseUnitType(java.lang.String inputStr)

Gets the unit type. First it looks up any macro string, then converts the abbreviation for unit to a unit type

Parameters:

inputStr - the string that starts with the unit type

Returns:

a ParsedUnit containing only type information.

unitAbbrevToUnitType

public static PlatyConst.unit unitAbbrevToUnitType(java.lang.String unitStr)

Convert the abbreviation used for the unit into a unit-type (an enum in PlatyConst)

Parameters:

unitStr - the string that begins with the unit abbreviation

Returns:

the PlatyConst.unit enum that corresponds to the type or to an error
