<>methods to write constraint fields (use builder)

◆ GetID()

static const Standard_GUID& TDataXtd_Constraint::GetID ( )
static

Returns the GUID for constraints.

◆ GetPlane()

const Handle< TNaming_NamedShape >& TDataXtd_Constraint::GetPlane ( ) const

Returns the topological attribute of the plane used for planar - i.e., 2D - constraints. This plane is attached to another label. If the constraint is not planar, in other words, 3D, this function will return a null handle.

◆ GetType()

TDataXtd_ConstraintEnum TDataXtd_Constraint::GetType ( ) const

Returns the type of constraint. This will be an element of the TDataXtd_ConstraintEnum enumeration.

◆ GetValue()

const Handle< TDataStd_Real >& TDataXtd_Constraint::GetValue ( ) const

Returns the value of a dimension. This value is a reference to a TDataStd_Real attribute. If the attribute is not a dimension, this value will be 0. Use IsDimension to test this condition.

◆ ID()

const Standard_GUID& TDataXtd_Constraint::ID ( ) const
overridevirtual

Returns the ID of the attribute.

Implements TDF_Attribute.

◆ Inverted() [1/2]

void TDataXtd_Constraint::Inverted ( const Standard_Boolean  status)

◆ Inverted() [2/2]

Standard_Boolean TDataXtd_Constraint::Inverted ( ) const

◆ IsDimension()

Standard_Boolean TDataXtd_Constraint::IsDimension ( ) const

Returns true if this constraint attribute is a dimension, and therefore has a value.

◆ IsPlanar()

Returns true if this constraint attribute is two-dimensional.

◆ NbGeometries()

Standard_Integer TDataXtd_Constraint::NbGeometries ( ) const

This method is different from the "Copy" one, because it is used when copying an attribute from a source structure into a target structure. This method may paste the contents of <me> into <intoAttribute>.

The given pasted attribute can be full or empty of its contents. But don't make a NEW! Just set the contents!

It is possible to use <aRelocationTable> to get/set the relocation value of a source attribute.

Implements TDF_Attribute.

◆ References()

virtual void TDataXtd_Constraint::References ( const Handle< TDF_DataSet > &  aDataSet) const

Reimplemented from TDF_Attribute.

◆ Restore()
