TMethod Class Reference

Each ROOT class (see TClass) has a linked list of methods.

This class describes one single method (member function). The method info is obtained via the CINT api. See class TCling.

The method information is used a.o. by the THml class and by the TTree class.

Constructor & Destructor Documentation

◆ TMethod() [1/2]

TMethod::TMethod ( MethodInfo_t *  info = 0,
TClass cl = 0 
)

Default TMethod ctor.

TMethods are constructed in TClass. Comment strings are pre-parsed to find out whether the method is a context-menu item.

Definition at line 39 of file TMethod.cxx.

◆ TMethod() [2/2]

TMethod::TMethod ( const TMethod org)

Copy ctor.

Definition at line 54 of file TMethod.cxx.

◆ ~TMethod()

TMethod::~TMethod ( )
virtual

Cleanup.

Definition at line 86 of file TMethod.cxx.

Member Function Documentation

◆ Clone()

TObject * TMethod::Clone ( const char *  newname = "") const
virtual

Clone method.

Reimplemented from TFunction.

Definition at line 95 of file TMethod.cxx.

◆ CreateSignature()

void TMethod::CreateSignature ( )
privatevirtual

Using the CINT method arg information create a complete signature string.

Reimplemented from TFunction.

Definition at line 114 of file TMethod.cxx.

◆ FindDataMember()

TDataMember * TMethod::FindDataMember ( )
virtual

Tries to guess DataMember from comment string and Method's name <==(only if 1 Argument!).

If more then one argument=> returns pointer to the last argument. It also sets MethodArgs' pointers to point to specified data members.

The form of comment string defining arguments is: void XXX(Int_t x1, Float_t y2) //*ARGS={x1=>fX1,y2=>fY2} where fX1, fY2 are data fields in the same class. ("pointers" to data members)

Definition at line 132 of file TMethod.cxx.

inline

Definition at line 55 of file TMethod.h.

◆ GetCommentString()

const char * TMethod::GetCommentString ( )
virtual

Returns a comment string from the class declaration.

Definition at line 105 of file TMethod.cxx.

◆ GetListOfMethodArgs()

TList * TMethod::GetListOfMethodArgs ( )

Bool_t TMethod::IsValid ( )
virtual

Return true if this function object is pointing to a currently loaded function.

If a function is unloaded after the TMethod is created, the TMethod will be set to be invalid.

Definition at line 276 of file TMethod.cxx.

◆ operator=()

TMethod & TMethod::operator= ( const TMethod rhs)

Assignment operator.

Definition at line 66 of file TMethod.cxx.

virtual void TMethod::SetMenuItem ( EMenuItemKind  menuItem)
inlinevirtual

Definition at line 64 of file TMethod.h.

◆ SetterMethod()

TMethodCall * TMethod::SetterMethod ( )
virtual

Return call environment for this method in case this is a *TOGGLE method which takes a single boolean or integer argument.

Definition at line 294 of file TMethod.cxx.

◆ Update()

Bool_t TMethod::Update ( MethodInfo_t *  info)
virtual

Update the TMethod to reflect the new info.

This can be used to implement unloading (info == 0) and then reloading (info being the 'new' decl address).
