◆ GetName()

const char * TEnvRec::GetName ( ) const

Returns name of object.

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

◆ Hash()

ULong_t TEnvRec::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.

TEnvRec::Hash

ULong_t Hash() const

Return hash value for this object.

Definition TEnv.h:113

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

TROOT::RecursiveRemove

void RecursiveRemove(TObject *obj)

Recursively remove this object from the list of Cleanups.
