TGeoPgon Class Reference

Polygons are defined in the same way as polycones, the difference being just that the segments between consecutive Z planes are regular polygons.

The phi segmentation is preserved and the shape is defined in a similar manner, just that rmin and rmax represent the radii of the circles inscribed in the inner/outer polygon.

The constructor of a polygon has the form:

TGeoPgon(Double_t phi1,Double_t dphi,Int_t nedges,Int_t nz);

The extra parameter nedges represent the number of equal edges of the polygons, between phi1 and phi1+dphi.

Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op )

staticprivateinherited

Private helper function which will dispatch to TObjectTable::AddObj.

Included here to avoid circular dependency between header files.

CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

staticinherited

Test whether a given axis is a separating axis for two oriented boxes.

The test is based on the Separating Axis Theorem (SAT). The boxes are projected onto the axis L using a center-plus-radius formulation, avoiding explicit vertex enumeration.

Tolerance handling: Two boxes that only touch (face, edge, or corner contact) within TGeoShape::Tolerance() are considered NON-intersecting.

Formally, the axis separates the boxes if:

|(oB - oA) · L| >= rA(L) + rB(L) - tol

where rA and rB are the projection radii of each box onto L.

Parameters

[in]	L	Candidate separating axis in world coordinates.
[in]	D	Vector from center of box A to center of box B (oB - oA).
[in]	Ax	World-space X axis of box A.
[in]	Ay	World-space Y axis of box A.
[in]	Az	World-space Z axis of box A.
[in]	Bx	World-space X axis of box B.
[in]	By	World-space Y axis of box B.
[in]	Bz	World-space Z axis of box B.
[in]	dA	Half-length vector of box A.
[in]	dB	Half-length vector of box B.
[in]	tol	Geometric tolerance (typically TGeoShape::Tolerance()).

Returns

true If L is a separating axis (boxes do NOT intersect).

false If L does not separate the boxes or is degenerate.

MayIntersect()

bool TGeoBBox::MayIntersect ( const TGeoBBox * boxA, const TGeoMatrix * mA, const TGeoBBox * boxB, const TGeoMatrix * mB )

staticinherited

Fast "may-intersect" test for two placed TGeoBBox objects.

This method implements a broad-phase oriented bounding box (OBB) intersection test using the Separating Axis Theorem (SAT).

The test is optimized for fast rejection:

• bounding-sphere early exit,
• face-normal axes tested first,
• cross-product axes tested only if needed.

Geometry and tolerance semantics:

• Boxes are treated as oriented bounding boxes defined by their half-lengths and placement matrices.
• TGeoBBox::GetOrigin() is fully taken into account.
• Boxes that only touch within TGeoShape::Tolerance() are considered NON-intersecting.

Intended usage:

• Broad-phase culling in navigation or overlap checks.
• Conservative test: returning true means the boxes MAY intersect.

Parameters

[in]	boxA	Pointer to the first TGeoBBox shape.
[in]	mA	Placement matrix of the first box.
[in]	boxB	Pointer to the second TGeoBBox shape.
[in]	mB	Placement matrix of the second box.

Returns

true If the boxes MAY intersect.

Notify()

Bool_t TObject::Notify ( )

virtualinherited

This method must be overridden to handle object notification (the base implementation is no-op).

Different objects in ROOT use the Notify method for different purposes, in coordination with other objects that call this method at the appropriate time.

For example, TLeaf uses it to load class information; TBranchRef to load contents of referenced branches TBranchRef; most notably, based on Notify, TChain implements a callback mechanism to inform interested parties when it switches to a new sub-tree.

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
