[mrpt-containers]

Container and STL-helper classes.

Library mrpt-containers

This C++ library is part of MRPT and can be installed in Debian-based systems with:

sudo apt install libmrpt-containers-dev

Read also how to import MRPT into your CMake scripts.

Find below some examples of use.

YAML-like parameter container

See mrpt::containers::yaml, and the examples therein.

Typedefs

typedef internal::generic_copier_ptr<T, internal::CopyCloner<T>> mrpt::containers::poly_ptr

Smart pointer for polymorphic classes with a clone() method.

No shared copies, that is, each poly_ptr<T> owns a unique instance of T. Copying a poly_ptr<T> invokes the copy operator for T.

copy_ptr<T>

typedef internal::generic_copier_ptr<T, internal::CopyStatic<T>> mrpt::containers::copy_ptr

Smart pointer for non-polymorphic classes.

No shared copies, that is, each copy_ptr<T> owns a unique instance of T. Copying a copy_ptr<T> invokes the copy operator for T.

See also:

poly_ptr<T>

Global Functions

template <typename src_container, typename dst_container>
void mrpt::containers::copy_container_typecasting(
    const src_container& src,
    dst_container& trg
    )

Copy all the elements in a container (vector, deque, list) into a different one performing the appropriate typecasting.

The target container is automatically resized to the appropriate size, and previous contents are lost. This can be used to assign std::vector’s of different types:

std::vector<int>    vi(10);
std::vector<float>  vf;
vf = vi;   // Compiler error
mrpt::containers::copy_container_typecasting(v1,vf);  // Ok
