Description

Lightweight string class, used internally in some parts of OMNeT++.

In simulation models it is better to use std::string or const char * instead.

opp_string has only one data member, a char* pointer. Allocation and deallocation of the contents takes place via opp_strdup() and operator delete.

Member Function Documentation

◆ c_str()

const char * c_str ( ) const
inline

Return pointer to the string.

Referenced by operator+(), operator+(), and cValue::set().

◆ str()

std::string str ( ) const
inline

Convert to std::string.

◆ empty()

bool empty ( ) const
inline

Null (empty) string or not.

◆ buffer()

char * buffer ( )
inline

Returns pointer to the internal buffer where the string is stored. It is allowed to write into the string via this pointer, but the length of the string should not be exceeded.

◆ size()

int size ( ) const
inline

Returns the length of the string.

Referenced by reserve().

◆ reserve()

char * reserve ( unsigned size)
inline

Allocates a buffer of the given size.

References size().

◆ operator=() [1/3]

const char * operator= ( const char * s)
inline

Deletes the old value and opp_strdup()'s the new value to create the object's own copy.

opp_string & operator= ( const opp_string & s)
inline

Assignment.
