| FlexFile::~FlexFile | ( | ) | [virtual] |
| FlexFile::ENABLE_RUNTIME_CLASSTYPE | ( | ) |
Reimplemented from ArchiveFile.
| virtual bool FlexFile::exists | ( | const std::string & | name | ) | [inline, virtual] |
Check if named object exists If the Flex is not named, name must be an integer with an optional extension
| name | name of object to check for |
Implements ArchiveFile.
Definition at line 35 of file FlexFile.h.
References exists(), and nameToIndex().
| virtual bool FlexFile::exists | ( | uint32 | index | ) | [inline, virtual] |
Check if numbered object exists If the Flex has named objects, only objects with numerical names will be returned (the filename without the extension must be an integer)
| index | index of object to check for |
Implements ArchiveFile.
Definition at line 34 of file FlexFile.h.
References getSize().
Referenced by exists().
| virtual uint32 FlexFile::getCount | ( | ) | [inline, virtual] |
Get upper bound for number of objects. In an indexed file this is (probably) the highest index plus one, while in a named file it's (probably) the actual count
Implements ArchiveFile.
Definition at line 62 of file FlexFile.h.
References count.
Referenced by World::loadNonFixed().
| virtual uint32 FlexFile::getIndexCount | ( | ) | [inline, virtual] |
Get the highest index in the file Guaranteed to be sufficiently large for a vector that needs to store the indexed entries of this file
Implements ArchiveFile.

Referenced by FlexWriter::FlexWriter(), and main().
| virtual uint8* FlexFile::getObject | ( | const std::string & | name, | |

| ) | [inline, virtual] |
Get named object from file; returns NULL if name is invalid. Must delete the returned buffer afterwards. See also exists(std::string name)
| name | name of object to fetch | |
| size | if non-NULL, size of object is stored in *size |
Implements ArchiveFile.
