## Detailed Description

A subunit in a CompositeUnit.

Should normally not be used directly.

## Member Function Documentation

## convertFromFirstBaseUnit()

virtual MathStructure & AliasUnit_Composite::convertFromFirstBaseUnit | ( | MathStructure & | mvalue,
|  | MathStructure & | mexp
| ) |  | const

virtual

Reimplemented from AliasUnit.

## convertToFirstBaseUnit()

virtual MathStructure & AliasUnit_Composite::convertToFirstBaseUnit | ( | MathStructure & | mvalue,
|  | MathStructure & | mexp
| ) |  | const

virtual

Reimplemented from AliasUnit.

## copy()

virtual ExpressionItem * AliasUnit_Composite::copy | ( |  | ) | const

virtual

Reimplemented from AliasUnit.

## print() [1/2]

virtual std::string AliasUnit_Composite::print | ( | bool | plural_,
|  | bool | short_,
|  | bool | use_unicode = `false`,
|  | bool(*)(const char *, void *) | can_display_unicode_string_function = `NULL`,
|  | void * | can_display_unicode_string_arg = `NULL`
| ) |  | const

virtual

Returns a display string representing the unit in an expression.

Equivalent to preferredName() for Unit and AliasUnit, but closer to MathStructure::print() for CompositeUnit (prints out base expression).

Reimplemented from Unit.

## print() [2/2]

virtual std::string AliasUnit_Composite::print | ( | const PrintOptions & | po,
|  | bool | format = `false`,
|  | int | tagtype = `0`,
|  | bool | input = `false`,
|  | bool | plural = `true`
| ) |  | const

virtual

Reimplemented from Unit.

## set()

virtual void AliasUnit_Composite::set | ( | const ExpressionItem * | item | ) |

virtual

Reimplemented from AliasUnit.
