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.
struct Bar { int i; int k; const char* data; struct Key; bool operator==(const Bar::Key& rhs) const; }; struct Bar::Key { Key(int a, int b) : i(a), k(b) {} int i; int k; }; bool Bar::operator==(const Bar::Key& key) const // definition { return i == key.i && k == key.k; } const Bar bars[] = { { 1, 1, "bar data 1" }, { 1, 2, "bar data 2" }, { 1, 3, "bar data 3" } }; int main ( void ) { const Bar* bar = find(bars, Bar::Key(1, 3)); if (bar) std::cout << bar->data << "\n"; else std::cout << "Key not found.\n"; return 0; } |

Very simple conversion of a float to a Rational. Test it with the values that you expect and check the implementation to see if this is really what you want! |
|
Return the greatest common denominator of n and m. (Implementation from Boost rational.hpp).
|
|
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.
|
|
Return a float set to the value represented by s. Besides strings that represent float values, the function also handles long, Rational and boolean (see also: stringTo(const std::string& s, bool& ok)).
|
|
Return a long set to the value represented by s. Besides strings that represent long values, the function also handles float, Rational and boolean (see also: stringTo(const std::string& s, bool& ok)).
|
|
Return a Rational set to the value represented by s. Besides strings that represent Rational values, the function also handles long, float and boolean (see also: stringTo(const std::string& s, bool& ok)). Uses floatToRationalCast(float f) if the string can be parsed into a float.
|
|
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. |

Utility function to convert a string to a value of type
The string representation of the value must match that recognized by the input operator for
|
|
Specialization of stringTo(const std::string& s, bool& ok) for bool.
Handles the same string values as the XMP SDK. Converts the string to lowercase and returns |

Test the version of the available Exiv2 library at runtime. Return true if it is the same as or newer than the passed-in version. Versions are denoted using a triplet of integers: major.minor.patch .
// Don't include the <exiv2/version.hpp> file directly, it is included by // <exiv2/types.hpp>. Early Exiv2 versions didn't have version.hpp and the macros. #include <exiv2/types.hpp> // Make sure an EXIV2_TEST_VERSION macro exists: #ifdef EXIV2_VERSION # ifndef EXIV2_TEST_VERSION # define EXIV2_TEST_VERSION(major,minor,patch) \ ( EXIV2_VERSION >= EXIV2_MAKE_VERSION(major,minor,patch) ) # endif #else # define EXIV2_TEST_VERSION(major,minor,patch) (false) #endif std::cout << "Compiled with Exiv2 version " << EXV_PACKAGE_VERSION << "\n" << "Runtime Exiv2 version is " << Exiv2::version() << "\n"; // Test the Exiv2 version available at runtime but compile the if-clause only if // the compile-time version is at least 0.15. Earlier versions didn't have a // testVersion() function: #if EXIV2_TEST_VERSION(0,15,0) if (Exiv2::testVersion(0,13,0)) { std::cout << "Available Exiv2 version is equal to or greater than 0.13\n"; } else { std::cout << "Installed Exiv2 version is less than 0.13\n"; } #else std::cout << "Compile-time Exiv2 version doesn't have Exiv2::testVersion()\n"; #endif |

Convert a value of type T to data, write the data to 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.
