Member Function Documentation

count()

uint32_t OpenRaw::Internals::IfdEntry::count ( ) const

inlinenoexcept

the count of items in the entry

Definition at line 178 of file ifdentry.hpp.

getArray()

template<typename T >

Option<std::vector<T> > OpenRaw::Internals::IfdEntry::getArray ( )

inline

get the array values of type T

Parameters

T	the type of the value needed
array	the storage

Exceptions

whatever

is thrown

Definition at line 216 of file ifdentry.hpp.

loadData()

bool OpenRaw::Internals::IfdEntry::loadData

(

size_t

unit_size

)

load the data for the entry if all the data fits in m_data, it is a noop

Parameters

unit_size

the size of 1 unit of data

Returns

true if success.

offset()

off_t OpenRaw::Internals::IfdEntry::offset ( )

inlinenoexcept

the offset of the data. It can just be the value if the entry is self contained.
