Member Function Documentation

Clear()

void ON_SubDRef::Clear

(

)

Description: Remove this reference to the managed ON_SubD. If this is the last reference, then the managed ON_SubD is deleted.

CopySubD() [1/2]

class ON_SubD& ON_SubDRef::CopySubD

(

const ON_SubD &

src

)

Description: Allocates a new ON_SubD and has this ON_SubDRef reference it. Parameters: src - [in] The new ON_SubD managed by this ON_SubDRef will be a copy of src. Returns: A reference to the new ON_SubD managed by this ON_SubDRef.

CopySubD() [2/2]

class ON_SubD& ON_SubDRef::CopySubD

(

const ON_SubDRef &

src

)

Description: Allocates a new ON_SubD and has this ON_SubDRef reference it. Parameters: src - [in] The new ON_SubD managed by this ON_SubDRef will be a copy of src.SubD(). Returns: A reference to the new ON_SubD managed by this ON_SubDRef.

CreateReferenceForExperts()

static ON_SubDRef ON_SubDRef::CreateReferenceForExperts ( const ON_SubD &  subd )

static

Description: Expert user function to have this ON_SubDRef reference the contents of an existing ON_SubD. Do not use if user data on the referenced subd needs to be accessed. Parameters: subd - [in] Any subd on the heap or the stack. Returns: true if successful.

EdgeIterator()

class ON_SubDEdgeIterator ON_SubDRef::EdgeIterator

(

)

const

FaceIterator()

class ON_SubDFaceIterator ON_SubDRef::FaceIterator

(

)

const

NewSubD()

class ON_SubD& ON_SubDRef::NewSubD

(

)

Description: Allocates a new empty ON_SubD and has this ON_SubDRef reference it.

operator=()

ON_SubDRef& ON_SubDRef::operator=

(

const ON_SubDRef &

src

)

ReferenceCount()

unsigned int ON_SubDRef::ReferenceCount

(

)

const

Returns: Number of references to the managed ON_SubD, including the one by this ON_SubDRef.

SetSubDForExperts()

class ON_SubD* ON_SubDRef::SetSubDForExperts

(

class ON_SubD *&

subd

)

Description: Expert user function to have this ON_SubDRef manage the lifetime of subd. Parameters: subd - [in/out] subd must point to an ON_SubD that was constructed on the heap using an operator new call with a public ON_SubD constructor. Returns: a pointer to the managed subd or nullptr subd if not valid. Example: ON_SubD* subd = new ON_SubD(...); ON_SubDRef subr; ON_SubD* managed_subd = subdr.SetSubD(subd); / subd = nullptr / managed_subd = pointer you can use

SubD()

const class ON_SubD& ON_SubDRef::SubD

(

)

const

UniqueSubD()

class ON_SubD& ON_SubDRef::UniqueSubD

(

)

Description: If ReferenceCount() > 1, then have this ON_SubDRef reference a new copy. Otherwise do nothing. The result being that this will be the unique reference to the ON_SubD managed by this ON_SubDRef. Returns: A reference to the ON_SubD uniquely managed by this ON_SubDRef.

VertexIterator()

class ON_SubDVertexIterator ON_SubDRef::VertexIterator

(
