SetLabel()

void IGESData_IGESEntity::SetLabel	(	const Handle< TCollection_HAsciiString > &	label,
		const Standard_Integer	sub = -1 )

Sets a new Label to an IGES Entity If _{is given, it sets value of SubScriptNumber else, SubScriptNumber is erased.}

SetLineWeight()

void IGESData_IGESEntity::SetLineWeight	(	const Standard_Real	defw,
		const Standard_Real	maxw,
		const Standard_Integer	gradw )

computes and sets "true" line weight according IGES rules from global data MaxLineWeight (maxv) and LineWeightGrad (gradw), or sets it to defw (Default) if LineWeightNumber is null

ShortLabel()

Handle< TCollection_HAsciiString > IGESData_IGESEntity::ShortLabel

(

)

const

Returns the label value for this IGES entity as a string. Warning If the label is blank, this string is null.

SingleView()

Handle< IGESData_ViewKindEntity > IGESData_IGESEntity::SingleView

(

)

const

Returns the view as a single view if it was defined as such and not as a list of views. Warning A null handle is returned if DefView does not have the value DefOne.

Structure()

Handle< IGESData_IGESEntity > IGESData_IGESEntity::Structure

(

)

const

Returns Structure (used by some types of IGES Entities only) Returns a Null Handle if Structure is not defined.

SubordinateStatus()

Standard_Integer IGESData_IGESEntity::SubordinateStatus

(

)

const

gives Subordinate Switch (0-1-2-3)

SubScriptNumber()

Standard_Integer IGESData_IGESEntity::SubScriptNumber

(

)

const

Returns the integer subscript number used to identify this IGES entity. Warning 0 is returned if no subscript number is defined for this IGES entity.

Transf()

Handle< IGESData_TransfEntity > IGESData_IGESEntity::Transf

(

)

const

Returns the Transformation Matrix (under IGES definition) Returns a Null Handle if there is none for a more complete use, see Location & CompoundLocation.

TypedAssociativity()

Handle< IGESData_IGESEntity > IGESData_IGESEntity::TypedAssociativity

(

const Handle< Standard_Type > &

atype

)

const

returns the Associativity of a given Type (if only one exists) Error if none or more than one

TypedProperty()

Handle< IGESData_IGESEntity > IGESData_IGESEntity::TypedProperty	(	const Handle< Standard_Type > &	atype,
		const Standard_Integer	anum = 0 ) const

returns the Property of a given Type Error if none or more than one

TypeNumber()

Standard_Integer IGESData_IGESEntity::TypeNumber

(

)

const

gives IGES Type Number (often coupled with Form Number)

UniqueParent()

Handle< IGESData_IGESEntity > IGESData_IGESEntity::UniqueParent

(

)

const

Returns the Unique Parent (in the sense given by HasOneParent) Error if there is none or several.

UseFlag()

Standard_Integer IGESData_IGESEntity::UseFlag

(

)

const

gives Entity's Use Flag (0 to 5)

VectorLocation()

gp_GTrsf IGESData_IGESEntity::VectorLocation

(

)

const

Returns Location considered for Vectors, i.e. without its Translation Part. As Location, it gives local definition.

View()

Handle< IGESData_ViewKindEntity > IGESData_IGESEntity::View

(

)

const

Returns the view of this IGES entity. This view can be a single view or a list of views. Warning A null handle is returned if the view is not defined.

ViewList()

Handle< IGESData_ViewKindEntity > IGESData_IGESEntity::ViewList

(

)

const

Returns the view of this IGES entity as a list. Warning A null handle is returned if the definition status does not have the value DefSeveral.
