at()

template<typename T >

T nnfw::misc::feature::Object< T >::at ( uint32_t  ch, uint32_t  row, uint32_t  col  ) const

inlineoverridevirtual

Get the value used by three indexes.

Parameters

[in]	ch	The depth index

[in]	col	The width index

Returns

The value at the offset

Implements nnfw::misc::feature::Reader< T >.
