Metafunctions - also known as "traits" or "trait classes" - return types, constants or functions for a set of given types or constants. They can be seen as part of a (meta-)program that is evaluated at compile time to produce a C++ program.
Read here an introduction to metafunctions and how to use them.
AllowsFastRandomAccessDetermines whether a sequence efficiently supports random access.
AlphabetAccess to the Alphabet type.
BitsPerValueNumber of bits needed to store a value.
BytesPerValueNumber of bytes needed to store a value.
CargoType of additional data stored in an object.
ColType of a column in an alignment.
ColsType of column container of an alignment.
ComparatorType of comparator object
CompareTypeType to convert other types for comparisons.
ContainerType of the container given an iterator.
ConvertReturn type of a conversion.

SpecThe spec of a class.
StdContainerIteratorReturns type of the STL container iterator.
StringSetTypeReturn type of stringSet function.
SuffixSuffix sequence type.
ValueType of the items in the container.
ValueSizeNumber of different values a value type object can have.
