Find an element that matches key in the array src. Designed to be used with lookup tables as shown in the example below. Requires a Key structure (ideally in the array) and a comparison operator to compare a key with an array element. The size of the array is determined automagically. Thanks to Stephan Broennimann for this nifty implementation.

Read a value of type T from the data buffer. We need this template function for the ValueType template classes. There are only specializations of this function available; no default implementation is provided.
|
|
Set the value of exifDatum to value. If the object already has a value, it is replaced. Otherwise a new ValueType<T> value is created and set to value. This is a helper function, called from Exifdatum members. It is meant to be used with T = (u)int16_t, (u)int32_t or (U)Rational. Do not use directly. |
