virtual void TVirtualMCGeometry::Mixture	(	Int_t &	kmat,
		const char *	name,
		Double_t *	a,
		Double_t *	z,
		Double_t	dens,
		Int_t	nlmat,
		Double_t *	wmat
	)

pure virtual

The same as previous but in double precision.

Implemented in TGeoMCGeometry.

◆ Mixture() [2/2]

virtual void TVirtualMCGeometry::Mixture	(	Int_t &	kmat,
		const char *	name,
		Float_t *	a,
		Float_t *	z,
		Double_t	dens,
		Int_t	nlmat,
		Float_t *	wmat
	)

pure virtual

Define mixture or compound with a number kmat composed by the basic nlmat materials defined by arrays a, z and wmat.

If nlmat > 0 then wmat contains the proportion by weights of each basic material in the mixture. If nlmat < 0 then wmat contains the number of atoms of a given kind into the molecule of the compound. In this case, wmat in output is changed to relative weights.

Implemented in TGeoMCGeometry.

◆ NofVolDaughters()

virtual Int_t TVirtualMCGeometry::NofVolDaughters ( const char * volName ) const

pure virtual

Return number of daughters of the volume specified by volName.

Implemented in TGeoMCGeometry.

◆ NofVolumes()

virtual Int_t TVirtualMCGeometry::NofVolumes ( ) const

pure virtual

Return total number of volumes in the geometry.

Implemented in TGeoMCGeometry.

◆ operator=()

◆ VolDaughterCopyNo()

virtual Int_t TVirtualMCGeometry::VolDaughterCopyNo	(	const char *	volName,
		Int_t	i
	)		const

pure virtual

Return the copyNo of i-th daughter of the volume specified by volName.

Implemented in TGeoMCGeometry.

◆ VolDaughterName()

virtual const char * TVirtualMCGeometry::VolDaughterName	(	const char *	volName,
		Int_t	i
	)		const

pure virtual

Return the name of i-th daughter of the volume specified by volName.

Implemented in TGeoMCGeometry.

◆ VolId()

virtual Int_t TVirtualMCGeometry::VolId ( const char * volName ) const

pure virtual

Return the unique numeric identifier for volume name volName.

Implemented in TGeoMCGeometry.

◆ VolId2Mate()

virtual Int_t TVirtualMCGeometry::VolId2Mate ( Int_t id ) const

pure virtual

Return material number for a given volume id.

Implemented in TGeoMCGeometry.

◆ VolName()

virtual const char * TVirtualMCGeometry::VolName ( Int_t id ) const

pure virtual

Return the volume name for a given volume identifier id.

Implemented in TGeoMCGeometry.
