TMethodArg Class Reference

Each ROOT method (see TMethod) has a linked list of its arguments.

This class describes one single method argument. The method argument info is obtained via the CINT api. See class TCling.

The method argument information is used a.o. in the TContextMenu and THtml classes.

Member Function Documentation

TDataMember * TMethodArg::GetDataMember ( ) const

Returns TDataMember pointed by this methodarg.

If you want to specify list of options or current value for your MethodArg (i.e. it is used as initial values in argument-asking dialogs popped up from context-meny),you can get this value from one of data members of the class.

The only restriction is, that this DataMember object must have its Getter/Setter methods set-up correctly - for details look at TDataMember. To learn how to specify the data member to which the argument should "point", look at TMethod. This is TMethod which sets up fDataMember, so it could work correctly.

const char * TMethodArg::GetDefault ( ) const
const char * TMethodArg::GetFullTypeName ( ) const

TList * TMethodArg::GetOptions ( ) const

Returns list of possible options - according to pointed datamember.

If there is no datamember field assigned to this methodarg - returns 0.

Definition at line 103 of file TMethodArg.cxx.

const char * TMethodArg::GetTypeName ( ) const

Get type of method argument, e.g.

: "class TDirectory*" -> "TDirectory" Result needs to be used or copied immediately.

std::string TMethodArg::GetTypeNormalizedName ( ) const

Get the normalized name of the return type.

A normalized name is fully qualified and has all typedef desugared except for the 'special' typedef which include Double32_t, Float16_t, [U]Long64_t and std::string. It also has std:: removed [This is subject to change].
