◆ ChangeValue()

void TEnvRec::ChangeValue ( const char *  v,
const char *  t,
EEnvLevel  l,
Bool_t  append = kFALSE,
Bool_t  ignoredup = kFALSE 
)
private

Change the value of a resource.

Definition at line 292 of file TEnv.cxx.

◆ Compare()

Int_t TEnvRec::Compare ( const TObject obj) const
privatevirtual

Comparison function for resources.

Reimplemented from TObject.

Definition at line 324 of file TEnv.cxx.

◆ ExpandValue()

TString TEnvRec::ExpandValue ( const char *  value)
private

Replace all strings by the value defined in the shell (obtained via TSystem::Getenv()).

Definition at line 333 of file TEnv.cxx.

◆ GetLevel()

EEnvLevel TEnvRec::GetLevel ( ) const
inline

Definition at line 113 of file TEnv.h.

◆ GetName()

const char* TEnvRec::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 110 of file TEnv.h.

◆ GetType()

const char* TEnvRec::GetType ( ) const
inline

Definition at line 112 of file TEnv.h.

◆ GetValue()

const char* TEnvRec::GetValue ( ) const
inline

Definition at line 111 of file TEnv.h.

◆ 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

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.
