Detailed Description

template<class valuetype>
class dynamicarray< valuetype >

The dynamicarray class allows you to store an arbitrary number of values and access them with array-like syntax.

Internally, the class stores these values in a series of extents. The size of the initial and incremental extents are defined in the constructor.

"valuetype" can be any scalar type, including a pointer, but cannot be an array.

Ie. these are legal: dynamicarray<int> d; dynamicarray<myclass> d; dynamicarray<myclass *> d;

These are not legal and whether they work or even compile would be platform-dependent: dynamicarray<int[100]> d; dynamicarray<myclass[100]> d; dynamicarray<myclass *[100]> d;

However, it is possible to create an array of arrays by nesting dynamicarrays and/or staticarrays, like:

dynamicarray<dynamicarray<int> > d;
dynamicarray<dynamicarray<myclass> > d;
dynamicarray<dynamicarray<myclass *> > d;
dynamicarray<staticarray<int> > d;
dynamicarray<staticarray<myclass> > d;
dynamicarray<staticarray<myclass *> > d;

NOTE: If "valuetype" is a pointer and either of collection::setManageValues(true) or collection::setManageArrayValue(true) are called, then all elements of the dynamicarray prior to the highest set element must also be set to something.

For example, if element 9 is set to some value then elements 0-8 must also be set to some value. They may be set to 0 or NULL, but they must be set.

Otherwise attempts to delete the uninitialized elements during calls to clear() or the destructor will likely cause the program to crash.

Constructor & Destructor Documentation

dynamicarray() [1/4]

template<class valuetype >

dynamicarray< valuetype >::dynamicarray

inline

Creates an empty instance of the dynamicarray class.

dynamicarray() [2/4]

template<class valuetype >

dynamicarray< valuetype >::dynamicarray ( uint64_t  initiallength, uint64_t  incrementlength  )

inline

Creates an empty instance of the dynamicarray class. The initial extent will be created with "initiallength" members and each successive extent will be created with "incrementlength" members.

dynamicarray() [3/4]

template<class valuetype >

dynamicarray< valuetype >::dynamicarray ( dynamicarray< valuetype > &  v )

inline

Creates an instance of the dynamicarray class that is a copy of "v".

dynamicarray() [4/4]

template<class valuetype >

dynamicarray< valuetype >::dynamicarray ( arraycollection< valuetype > &  v )

inline

Creates an instance of the dynamicarray class that is a copy of "v".

~dynamicarray()

template<class valuetype >

dynamicarray< valuetype >::~dynamicarray

inline

Deletes this instance of the dynamicarray class and all of its values.

Member Function Documentation

clear() [1/2]

template<class valuetype >

bool dynamicarray< valuetype >::clear

inlinevirtual

Clears the array.

Always returns true.

Implements collection.

clear() [2/2]

template<class valuetype >

bool dynamicarray< valuetype >::clear ( uint64_t  initiallength, uint64_t  incrementlength  )

inline

Clears the array and resets the lengths of the initial and incremental extents.

getCount()

template<class valuetype >

uint64_t dynamicarray< valuetype >::getCount

inlinevirtual

Returns the number of elements in the array.

Implements collection.

operator=() [1/2]

template<class valuetype >

dynamicarray< valuetype > & dynamicarray< valuetype >::operator= ( arraycollection< valuetype > &  v )

inline

Makes this instance of the dynamicarray class identical to "v".

operator=() [2/2]

template<class valuetype >

dynamicarray< valuetype > & dynamicarray< valuetype >::operator= ( dynamicarray< valuetype > &  v )

inline

Makes this instance of the dynamicarray class identical to "v".

operator[]()

template<class valuetype >

valuetype & dynamicarray< valuetype >::operator[] ( uint64_t  index )

inlinevirtual

Provides read/write access to the "index"th element of the dynamicarray.

Implements arraycollection< valuetype >.
