Detailed Description

Class representing the Segmentation Functional Group Macro.

Member Function Documentation

◆ check()

OFCondition FGSegmentation::check ( ) const
virtual

Check whether data in this functional group is valid.

Returns
EC_Normal if data is valid, error otherwise

Implements FGBase.

◆ clone()

virtual FGBase* FGSegmentation::clone ( ) const
virtual

Returns a deep copy of this object.

Returns
Deep copy of this object

Implements FGBase.

◆ compare()

virtual int FGSegmentation::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 FGSegmentation) 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
rhsthe 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 rhs object, or all compared components match but the rhs 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 the rhs object, or all compared components match but the rhs component is longer.

Implements FGBase.

◆ getReferencedSegmentNumber()

virtual OFCondition FGSegmentation::getReferencedSegmentNumber ( Uint16 &  value,
const unsigned long  pos = 0 
)
virtual

Get Referenced Segment Number.

Parameters
valueReference to variable in which the value should be stored
posIndex value to get (0..vm-1)
Returns
EC_Normal if successful, an error code otherwise

◆ getSharedType()

virtual DcmFGTypes::E_FGSharedType FGSegmentation::getSharedType ( ) const
inlinevirtual

Returns that this functional group can be used shared or per-frame, i.e. both.

Returns
Always returns DcmFGTypes::EFGS_BOTH

Implements FGBase.

References DcmFGTypes::EFGS_BOTH.

◆ read()

virtual OFCondition FGSegmentation::read ( DcmItem item)
virtual

Read functional group from item, must contain the Segment Identification Sequence.

Parameters
itemThe item to read from
Returns
EC_Normal if reading was successful, error otherwise

Implements FGBase.

◆ setReferencedSegmentNumber()

virtual OFCondition FGSegmentation::setReferencedSegmentNumber ( const Uint16 &  segmentNumber)
virtual

Set Referenced Segment Number.

Parameters
segmentNumberValue to be set
Returns
EC_Normal if successful, an error code otherwise

◆ write()

virtual OFCondition FGSegmentation::write ( DcmItem item)
virtual

Write functional group to item, will write Segment Identification Sequence.

Parameters
itemThe item to write to
Returns
EC_Normal if writing was successful, error otherwise

Implements FGBase.
