Function Documentation

◆ make_nested_ei()

template<class Exc >
EI_Nested make_nested_ei ( Exc &  e)

Create EI_Nested error info with given exception.

Used for propagation exception message.

Definition at line 272 of file exceptions.hh.

Here is the caller graph for this function:

◆ make_nested_message()

template<class Exc >
EI_NestedMessage make_nested_message ( Exc &  e)

Propagate just the 'what' message for exceptions that are not derived from ExceptionBase.

Definition at line 285 of file exceptions.hh.

Here is the caller graph for this function:

◆ TYPEDEF_ERR_INFO() [1/2]

TYPEDEF_ERR_INFO ( EI_Nested  ,
std::shared_ptr< ExceptionBase  
)

Error info of previous exception.

Allows keep and propagate message when one exception is catched and other exception is thrown. Catched exception is stored to EI_Nested and is printed out to message of thrown exception.

Example of usage:

try {
// method next() throws ExcA
obj.next();
} catch ( ExcA &e ) {
// add ExcA to EI tags of ExcB
THROW( ExcB() << make_nested_ei(e)) );
}

◆ TYPEDEF_ERR_INFO() [2/2]

TYPEDEF_ERR_INFO ( EI_NestedMessage  ,
std::string   
)
make_nested_ei
EI_Nested make_nested_ei(Exc &e)
Definition: exceptions.hh:272
THROW
#define THROW(whole_exception_expr)
Wrapper for throw. Saves the throwing point.
