get()

template<typename T >

T OpenRaw::Internals::IfdTypeTrait< T >::get ( IfdEntry &  e, uint32_t  idx = 0, bool  ignore_type = false  )

staticnoexcept

get the value of type T

Parameters

T	the type of the value needed
idx	the index, by default 0
ignore_type	if true, don't check type. DANGEROUS Default is false.

Returns

the value

Exceptions

BadTypeException	in case of wrong typing.
OutOfRangeException	in case of subscript out of range
