size_t	setOffset (size_t offset)
	Sets a new offset and returns the old value. This can be used to save/restore the current offset. Calling setOffset() after an overrun with an in-range (i.e. non-overrun) value restores the non-overrun status. More...

Detailed Description

template<serialization::Endian E>
class microstrain::Serializer< E >

Serializes or deserializes data to/from a byte buffer.

Create one of these to handle serialization or deserialization of one or more values to/from a buffer of bytes.

You can use this->insert/extract or directly call the insert/extract non- member functions taking a serializer reference.

The endianness is included as part of the Serializer's type so that it doesn't have to be repeatedly re-specified. It is not included as a runtime parameter for performance reasons (most of the time only a buffer of a known, specific endianness is required).

Template Parameters

E	Endianness of the target buffer.

Member Function Documentation

extract()

template<serialization::Endian E>

template<typename... Ts>

bool microstrain::Serializer< E >::extract

(

Ts &...

values

)

Deserializes one or more values.

This function defers to the non-member function microstrain::extract. By doing so, it allows the user to provide custom overloads for their own types. Any type supported by the non-member functions may be used here.

Template Parameters

Ts	Types of values to deserialize.

Parameters

[out]

values

One or more parameters to deserialize.

Returns

True if all values were successfully read.

extract_count() [1/2]

template<serialization::Endian E>

template<class T , class S >

bool microstrain::Serializer< E >::extract_count	(	T &	count,
		S	max_count
	)

Deserializes an integer with maximum permissible value.

This function is intended to be used with protocols which have embedded length fields. This function returns false and invalidates the serializer if the count is too large.

Template Parameters

T	Type of value to read. Expected to be integer-like and must support bool operator<=(S).
S	Type of the maximum value. Usually the same integral type as T, but the only requirement is that it can be compared with T.

Parameters

[out]	count	Value read from the buffer. Set to 0 on failure.
	max_count	Maximum permissible value for count (inclusive).

Returns

True if the count was successfully read and is less than or equal to max_count.

extract_count() [2/2]

template<serialization::Endian E>

template<class T , class S >

bool microstrain::Serializer< E >::extract_count ( T *  count, S  max_count  )

inline

insert()

template<serialization::Endian E>

template<typename... Ts>

bool microstrain::Serializer< E >::insert

(

const Ts &...

values

)

Serializes one or more values.

This function defers to the non-member function microstrain::insert. By doing so, it allows the user to provide custom overloads for their own types. Any type supported by the non-member functions may be used here.

Template Parameters

Ts	Types of values to serialize.

Parameters

values

One or more parameters to serialize.

Returns

True if all values were successfully written.
