Member Function Documentation
| size_t getArray | ( | uint8_t * | buf, |
| size_t | maxLen | ||
| ) |
Get array.
- Parameters:
-
buf pointer to buffer's start maxLen maximum number of bytes to copy
- Returns:
- number of copied bytes
Definition at line 129 of file TLVList.cpp.
| size_t getArrayLength | ( | ) |
| TLVList::TLVType getNext | ( | ) |
Iterate to next item.
- Returns:
- type if next item exists, NONE otherwise
Definition at line 36 of file TLVList.cpp.
| size_t getString | ( | char * | str, |
| size_t | maxLen | ||
| ) |
Get string.
Get string Copy string to buffer (including null-terminating char)
Copy string to buffer (including null-terminating char).
- Parameters:
-
str pointer to string's start maxLen maximum number of chars to copy (not including null-terminating char)
- Returns:
- number of copied chars
- Parameters:
-
str pointer to string's start maxLen maximum number of chars to copy (not including null-terminating char)
- Returns:
- number of copied chars
Definition at line 161 of file TLVList.cpp.
| size_t getStringLength | ( | ) |
| TLVList::TLVType getType | ( | ) |
Get current item's type.
- Returns:
- type if item exists, NONE otherwise
Definition at line 71 of file TLVList.cpp.
| uint32_t getUInt32 | ( | ) |
Get uint32_t value.
Get uint32_t value If the current item's type is uint8_t, the value will be casted to uint32_t.
If the current item's type is uint8_t, the value will be casted to uint32_t.
- Returns:
- uint32_t value OR 0 if the type is incompatible
- uint32_t value OR 0 if the type is incompatible
Definition at line 97 of file TLVList.cpp.
| uint8_t getUInt8 | ( | ) |
Get uint8_t value.
Get uint8_t value If the current item's type is uint32_t, the value will be masked with 0xFF.
If the current item's type is uint32_t, the value will be masked with 0xFF.
- Returns:
- uint8_t value OR 0 if the type is incompatible
- uint8_t value OR 0 if the type is incompatible
Definition at line 80 of file TLVList.cpp.
| bool isSpace | ( | ) |
Check whether there is space left in list.
- Returns:
- true if there is space left, false otherwise
Definition at line 178 of file TLVList.cpp.
| size_t putArray | ( | uint8_t * | buf, |
| size_t | len | ||
| ) |
Put array.
- Parameters:
-
buf pointer to buffer's start len number of bytes to copy
- Returns:
- number of copied bytes
Definition at line 218 of file TLVList.cpp.
| size_t putString | ( | char * | str ) |
Put string.
- Parameters:
-
str pointer to null-terminated string's start
- Returns:
- number of copied bytes
Definition at line 233 of file TLVList.cpp.
| bool putUInt32 | ( | uint32_t | value ) |
Put uint32_t value.
- Parameters:
-
value uint32_t value
- Returns:
- true on success, false if there is not enough space in buffer
Definition at line 202 of file TLVList.cpp.
| bool putUInt8 | ( | uint8_t | value ) |
Put uint8_t value.
- Parameters:
-
value uint8_t value
- Returns:
- true on success, false if there is not enough space in buffer
Definition at line 187 of file TLVList.cpp.
