opp_string Class Reference

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 opp_string::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.

reserve()

char* reserve ( unsigned  size )

inline

Allocates a buffer of the given 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.
