Member Function Documentation

◆ Browse()

void TPair::Browse ( TBrowser * b )

virtual

Browse the pair.

Reimplemented from TObject.

Definition at line 453 of file TMap.cxx.

◆ GetName()

const char * TPair::GetName ( ) const

inlinevirtual

Returns name of object.

This default method returns the class name. Classes that give objects a name should override this method.

Reimplemented from TObject.

Definition at line 116 of file TMap.h.

◆ GetTitle()

const char * TPair::GetTitle ( ) const

inlinevirtual

Returns title of object.

This default method returns the class title (i.e. description). Classes that give objects a title should override this method.

Reimplemented from TObject.

Definition at line 117 of file TMap.h.

◆ Hash()

ULong_t TPair::Hash ( ) const

inlinevirtual

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

ROOT::CallRecursiveRemoveIfNeeded

void CallRecursiveRemoveIfNeeded(TObject &obj)

call RecursiveRemove for obj if gROOT is valid and obj.TestBit(kMustCleanup) is true.

Definition TROOT.h:393

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

TObject

Mother of all ROOT objects.

Definition TObject.h:41

TObject::Error

virtual void Error(const char *method, const char *msgfmt,...) const

Issue error message.

Definition TObject.cxx:963

TPair::Hash

ULong_t Hash() const

Return hash value for this object.

void RecursiveRemove(TObject *obj)

Recursively remove this object from the list of Cleanups.

Definition TROOT.cxx:2456

Reimplemented from TObject.

Definition at line 118 of file TMap.h.

◆ IsEqual()

Bool_t TPair::IsEqual ( const TObject * obj ) const

inlinevirtual

Default equal comparison (objects are equal if they have the same address in memory).

More complicated classes might want to override this function.

◆ IsFolder()

Bool_t TPair::IsFolder ( ) const

inlinevirtual

Returns kTRUE in case object contains browsable objects (like containers or lists of other objects).
