## Detailed Description

Class representing the "CT Position" Functional Group Macro.

## Member Function Documentation

## ◆ check()

virtual OFCondition FGCTPosition::check | ( |  | ) | const
| virtual

Check whether the current content of this group is consistent and complete.

Returns
  EC_Normal, if no errors are found, error otherwise

Implements FGBase.

## ◆ clone()

virtual FGBase * FGCTPosition::clone | ( |  | ) | const
| virtual

Returns a deep copy of this object.

Returns
  Deep copy of this object

Implements FGBase.

References FGBase::FGBase().

## ◆ compare()

virtual int FGCTPosition::compare | ( | const FGBase & | rhs | ) | const
| virtual

Comparison operator that compares the normalized value of this object with a given object of the same type, i.e. the elements within both functional groups (this and rhs parameter) are compared by value!

Both objects (this and rhs) need to have the same type (i.e. both FGUnknown) to be comparable. This function is used in order to decide whether a functional group already exists, or is new. This is used in particular to find out whether a given functional group can be shared (i.e. the same information already exists as shared functional group) or is different from the same shared group. In that case the shared functional group must be distributed into per-frame functional groups, instead. The exact implementation for implementing the comparison is not relevant. However, it must be a comparison by value.

Parameters

  rhs | the right hand side of the comparison

Returns
  0 if the object values are equal. -1 if either the value of the first component that does not match is lower in the this object, or all compared components match but this component is shorter. Also returned if this type and rhs type (DcmFGTypes::E_FGType) do not match. 1 if either the value of the first component that does not match is greater in this object, or all compared components match but this component is longer.

Implements FGBase.
