◆ Compare()

template<class AParamType>

virtual Int_t TParameter< AParamType >::Compare ( const TObject * obj ) const

inlinevirtual

Compare abstract method.

Must be overridden if a class wants to be able to compare itself with other objects. Must return -1 if this is smaller than obj, 0 if objects are equal and 1 if this is larger than obj.

Reimplemented from TObject.

Definition at line 96 of file TParameter.h.

◆ GetName()

template<class AParamType>

const char* TParameter< AParamType >::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 68 of file TParameter.h.

◆ GetVal()

template<class AParamType>

const AParamType& TParameter< AParamType >::GetVal ( ) const

inline

Definition at line 69 of file TParameter.h.

◆ Hash()

template<class AParamType>

virtual ULong_t TParameter< AParamType >::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)

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.

Reimplemented from TObject.

inline

Definition at line 70 of file TParameter.h.

inlinevirtual

Reimplemented from TObject.

Definition at line 95 of file TParameter.h.

◆ ls()

template<class AParamType>

virtual void TParameter< AParamType >::ls ( Option_t * option ) const

inlinevirtual

The ls function lists the contents of a class on stdout.

Ls output is typically much less verbose then Dump().

Reimplemented from TObject.

Definition at line 104 of file TParameter.h.

◆ Merge() [1/2]

This method must be overridden when a class wants to print itself.
