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.

◆ TMethodArg() [1/2]

TMethodArg::TMethodArg ( const TMethodArg )
private

◆ TMethodArg() [2/2]

TMethodArg::TMethodArg ( MethodArgInfo_t *  info = 0,
TFunction method = 0 
)

Default TMethodArg ctor.

TMethodArgs are constructed in TFunction via a call to TCling::CreateListOfMethodArgs().

Definition at line 36 of file TMethodArg.cxx.

◆ ~TMethodArg()

TMethodArg::~TMethodArg ( )
virtual

TMethodArg dtor deletes adopted CINT MethodArgInfo object.

Member Function Documentation

◆ GetDataMember()

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.

Definition at line 121 of file TMethodArg.cxx.

◆ GetDefault()

const char * TMethodArg::GetDefault ( ) const

Get default value of method argument.

Definition at line 58 of file TMethodArg.cxx.

◆ GetFullTypeName()

const char * TMethodArg::GetFullTypeName ( ) const

Get full type description of method argument, e.g.: "class TDirectory*".

Definition at line 75 of file TMethodArg.cxx.

◆ GetMethod()

TFunction* TMethodArg::GetMethod ( ) const
inline

Definition at line 47 of file TMethodArg.h.

◆ GetOptions()

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.

◆ GetTypeName()

const char * TMethodArg::GetTypeName ( ) const

Get type of method argument, e.g.

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

Definition at line 67 of file TMethodArg.cxx.

◆ GetTypeNormalizedName()

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].

Definition at line 86 of file TMethodArg.cxx.

◆ operator=()

TMethodArg& TMethodArg::operator= ( const TMethodArg )
private

◆ Property()

Long_t TMethodArg::Property ( ) const
virtual

Get property description word. For meaning of bits see EProperty.

Implements TDictionary.

Definition at line 94 of file TMethodArg.cxx.

◆ Update()

void TMethodArg::Update ( MethodArgInfo_t *  info)

Update fInfo (to 0 for unloading and non-zero for reloading).

This takes ownership of 'info'
