Function Documentation

FlatVector() [1/3]

template<typename T >

void* FlatVector	(	std::vector< std::vector< T >> &	v,
		OutputVectorFlatDirection	direction,
		std::vector< unsigned long long > &	start_address,
		std::vector< unsigned long long > &	end_address,
		size_t &	v_size
	)

flat vector of vector to 1D vector direction specify row-major or colum major AU_FLAT_OUTPUT_ROW (0): row major, e.g., for a 2 by 2 vector of vector v[0][0] v[0][1] v[1][0] v[1][1] AU_FLAT_OUTPUT_COL (1): column major, e.g., for a 2 by 2 vector of vector v[0][0] v[1][0] v[0][1] v[1][1]

AU_FLAT_OUTPUT_RC: both row and column major, e.g. for a 2 by 2 vector of vector v[0][0] v[0][1] v[1][0] v[1][1] Then, linearized as v[0][0] v[0][1] v[1][0] v[1][1] It looks like AU_FLAT_OUTPUT_ROW, but the start_address and end_address are handled differently start_address is adjusted by v.size() end_address is adjusted by v[0].size()
AU_FLAT_OUTPUT_CR: both row and column major, e.g. for a 2 by 2 vector of vector

Since this is the support function to WriteEndpoint, It also convert the address associated with it.

Template Parameters

T	type of data element

Parameters

v	the vector of vector
direction	how to flat the data

Returns

void* the flat data
