wxVector< T > Class Template Reference

Detailed Description

template<typename T>
class wxVector< T >

wxVector<T> is a template class which implements most of the std::vector class and can be used like it.

If wxWidgets is compiled in STL mode, wxVector will just be a typedef to std::vector. Just like for std::vector, objects stored in wxVector<T> need to be assignable but don't have to be "default constructible".

Please refer to the STL documentation for further information.

Library:  None; this class implementation is entirely header-based.

Category:  Containers

void wxVector< T >::resize

(

size_type

n

)

Makes the vector of size n.

If n is less than the current size(), the elements at the end of the vector are erased. If it is greater, then the vector is completed with either the copies of the given object v or value_type() objects until it becomes of size n.

template<typename T >

void wxVector< T >::resize	(	size_type	n,
		const value_type &	v
	)

Makes the vector of size n.

If n is less than the current size(), the elements at the end of the vector are erased. If it is greater, then the vector is completed with either the copies of the given object v or value_type() objects until it becomes of size n.

template<typename T >

size_type wxVector< T >::size

(

wxVector< T > &

v

Efficiently exchanges contents of this vector with another one.

After the execution of this function the contents of this vector is equal to the original contents of v and the contents of v becomes the original contents of this vector without copying the data.
