virtual bool ucommon::DirPager::filter |
( |
const char * |
filename | ) |
|
|
protectedvirtual |
Filter filenames in a derived class.
- Parameters
-
- Returns
- true if include in final list.
const char* ucommon::DirPager::get |
( |
unsigned |
item | ) |
|
|
inline |
Get string item from list.
This is useful when stringpager is passed as a pointer and hence inconvenient for the [] operator.
- Parameters
-
- Returns
- pointer to text for item, or NULL if out of range.
Reimplemented from ucommon::stringpager.
Definition at line 589 of file memory.h.
bool ucommon::DirPager::load |
( |
const char * |
path | ) |
|
|
protected |
Load a directory path.
- Parameters
-
- Returns
- true if valid.
const char* ucommon::DirPager::operator[] |
( |
unsigned |
item | ) |
|
|
inline |
Return specified filename from directory list.
This is a convenience operator.
- Parameters
-
- Returns
- text of item or NULL if invalid.
