TlvBox

An easy-to-use TLV API in C plus plus.

It can help you construct & parse one or several TLV objects.

Building

g++ -o test Test.cpp TlvBox.cpp Tlv.cpp
./test

Usage

1. Public functions for encode

//put one TLV box
bool PutBoolValue(int type,bool value);
bool PutCharValue(int type,char value);
bool PutShortValue(int type,short value);
bool PutIntValue(int type,int value);
bool PutLongValue(int type,long value);
bool PutLongLongValue(int type,long long value);
bool PutFloatValue(int type,float value);
bool PutDoubleValue(int type,double value);
bool PutStringValue(int type,char *value);
bool PutStringValue(int type,const std::string &value);
bool PutBytesValue(int type,unsigned char *value,int length);
bool PutObjectValue(int type,const TlvBox& value);          

//do encode
bool Serialize(); 

//access encoded buffer and length
unsigned char * GetSerializedBuffer() const;
int GetSerializedBytes() const;

2. Public functions for decode

//do decode
bool Parse(const unsigned char *buffer,int buffersize); 

//get one TLV box
bool GetBoolValue(int type,bool &value) const;
bool GetCharValue(int type,char &value) const;
bool GetShortValue(int type,short &value) const;
bool GetIntValue(int type,int &value) const;
bool GetLongValue(int type,long &value) const;
bool GetLongLongValue(int type,long long &value) const;
bool GetFloatValue(int type,float &value) const;
bool GetDoubleValue(int type,double &value) const;
bool GetStringValue(int type,char *value,int &length) const;
bool GetStringValue(int type,std::string &value) const;
bool GetBytesValue(int type,unsigned char *value,int &length) const;
bool GetBytesValuePtr(int type,unsigned char **value,int &length) const;
bool GetObjectValue(int type,TlvBox& value) const;
