Member Function Documentation

◆ empty()

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::empty ( ) const
inline

Whether not initialized (no (name,value) pair remembered)

Definition at line 48 of file NamedValue.h.

◆ haveValue()

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::haveValue ( const std::string &  name_r) const
inline

Whether there is a value mapped for name_r.

Definition at line 56 of file NamedValue.h.

◆ getValue() [1/2]

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::getValue ( const std::string &  name_r,
Tp &  value_r 
) const
inline

Get value mapped for name or alias.

Returns
true if name or alias was found.

Definition at line 65 of file NamedValue.h.

◆ getValue() [2/2]

template<class Tp , const bool _tWithAlias = true>
const Tp& zypp::NamedValue< Tp, _tWithAlias >::getValue ( const std::string &  name_r) const
inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 74 of file NamedValue.h.

◆ haveName()

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::haveName ( const std::string &  value_r) const
inline

Whether there is a name mapped for value_r.

Definition at line 83 of file NamedValue.h.

◆ getName() [1/2]

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::getName ( const Tp &  value_r,
std::string &  name_r 
) const
inline

Get name of value.

Returns
true if name or alias was found.

Definition at line 92 of file NamedValue.h.

◆ getName() [2/2]

template<class Tp , const bool _tWithAlias = true>
const std::string& zypp::NamedValue< Tp, _tWithAlias >::getName ( const Tp &  value_r) const
inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 101 of file NamedValue.h.

◆ operator()()

template<class Tp , const bool _tWithAlias = true>
TInserter zypp::NamedValue< Tp, _tWithAlias >::operator() ( const Tp &  value_r)
inline

Definition at line 123 of file NamedValue.h.

◆ insert()

template<class Tp , const bool _tWithAlias = true>
bool zypp::NamedValue< Tp, _tWithAlias >::insert ( const Tp &  value_r,
const std::string &  name_r 
)
inline

Remember name (1st call) or alias (subsequent calls).

Returns
true if this is the 1st call for value_r.
Exceptions
std::logic_errorif name_r is already used as name or alias.
std::logic_errorif _tWithAlias is false and a name for value_r is already defined.
