ot::FrameData class
Represents a frame `Data` which is simply a wrapper over a pointer to a buffer with a given frame length. It provide helper method to parse the content. As data is parsed and read, the `FrameData` is updated to skip over the read content.
Syntax
class FrameData : public Data<kWithUint16Length>
{
public:
bool CanRead(uint16_t aLength) const { return GetLength() >= aLength; }
Error ReadUint8(uint8_t &aUint8);
Error ReadBigEndianUint16(uint16_t &aUint16);
Error ReadBigEndianUint32(uint32_t &aUint32);
Error ReadLittleEndianUint16(uint16_t &aUint16);
Error ReadLittleEndianUint32(uint32_t &aUint32);
Error ReadBytes(void *aBuffer, uint16_t aLength);
template <typename ObjectType> Error Read(ObjectType &aObject)
{
static_assert(!TypeTraits::IsPointer<ObjectType>::kValue, "ObjectType must not be a pointer");
return ReadBytes(&aObject, sizeof(ObjectType));
}
void SkipOver(uint16_t aLength);
};

Description
Parses the Fragment Header from a given frame data. If the Fragment Header is parsed successfully the @p aFrameData is updated to skip over the parsed header bytes.
Decompresses a LOWPAN_NHC UDP header. If the header is parsed successfully the @p aFrameData is updated to skip over the parsed header bytes.
Indicates whether or not the header (in a given frame) is a Fragment Header.
Indicates whether or not the header (in a given frame) is a Mesh Header.
Decompresses a LOWPAN_IPHC header. If the header is parsed successfully the @p aFrameData is updated to skip over the parsed header bytes.
