CDict< T > Class Template Reference

Description

template<typename T>
class CDict< T >

Dictionary.

A dictionary stores arbitrary (key, value) pairs. The key is always of type CString / const char *. Internally, the dictionary is stored in an array containing the (key, value) pairs, which is kept ordered by the keys.

The values are dynamically allocated objects, to which pointers are stored in the array. All 'Set...' methods require dynamic objects to be passed and take over their ownerships. On element deletion, these objects are deleted. It is legal to pass NULL to 'Set...' methods.

For any operations passing a new value object, the dictionary takes over the ownership: The pointer passed as 'value' remains valid until the entry is deleted from the list. Then it will be free'd using 'delete'.

Member Function Documentation

Set()

template<typename T >

int CDict< T >::Set ( const char *  key, T *  value  )

inline

Add or replace the keyed entry. Complexity is O(n).

Returns

Index of new entry

Definition at line 1212 of file base.H.

SetValue()

template<typename T >

void CDict< T >::SetValue ( int  idx, T *  value  )

inline

Set (replace) a value.

Parameters

idx	is the index.
value	must be a dynamically allocated object or 'NULL'. The dictionary will take over ownership and call 'delete' on it later. The entry must exist and 'idx' be valid. Complexity is O(1).

Definition at line 1215 of file base.H.

Merge()

template<typename T >

void CDict< T >::Merge ( CDict< T > *  dict2 )

inline

Merge another dictionary into this one. Complexity is O(n_this + n_dict2). 'dict2' will be empty afterwards.

The recommended way to add a bunch of new entries to a dictionary is to first add them to a new dictionary and then use this method to merge them into 'this'.
