## Detailed Description

### template<size_t cacheSize>
class Ogre::StaticCache< cacheSize >

Template version of cache based on static array.

'cacheSize' defines size of cache in bytes.

Definition at line 41 of file OgreDataStream.h.

## Constructor & Destructor Documentation

template<size_t cacheSize>

Ogre::StaticCache< cacheSize >::StaticCache | ( |  | ) |

Constructor.

Definition at line 54 of file OgreDataStream.h.

## Member Function Documentation

template<size_t cacheSize>

size_t Ogre::StaticCache< cacheSize >::avail | ( |  | ) | const

Returns number of bytes available for reading in cache after rewinding.

Definition at line 135 of file OgreDataStream.h.

Referenced by Ogre::StaticCache< 16 *OGRE_STREAM_TEMP_SIZE >::cacheData(), Ogre::StaticCache< 16 *OGRE_STREAM_TEMP_SIZE >::ff(), and Ogre::StaticCache< 16 *OGRE_STREAM_TEMP_SIZE >::read().

template<size_t cacheSize>

size_t Ogre::StaticCache< cacheSize >::cacheData | ( | const void * | buf,
|  | size_t | count
| ) |  |

Cache data pointed by 'buf'.

If 'count' is greater than cache size, we cache only last bytes. Returns number of bytes written to cache.

Definition at line 62 of file OgreDataStream.h.

template<size_t cacheSize>

void Ogre::StaticCache< cacheSize >::clear | ( | void |  | ) |

Clear the cache.

Definition at line 141 of file OgreDataStream.h.

Referenced by Ogre::StaticCache< 16 *OGRE_STREAM_TEMP_SIZE >::ff(), and Ogre::StaticCache< 16 *OGRE_STREAM_TEMP_SIZE >::rewind().

template<size_t cacheSize>

bool Ogre::StaticCache< cacheSize >::ff | ( | size_t | count | ) |

Step forward in cached stream by 'count' bytes.

Returns 'true' if cache contains resulting position.

Definition at line 120 of file OgreDataStream.h.

template<size_t cacheSize>

size_t Ogre::StaticCache< cacheSize >::read | ( | void * | buf,
|  | size_t | count
| ) |  |

Read data from cache to 'buf' (maximum 'count' bytes).

Returns number of bytes read from cache.

Definition at line 96 of file OgreDataStream.h.

template<size_t cacheSize>

bool Ogre::StaticCache< cacheSize >::rewind | ( | size_t | count | ) |

Step back in cached stream by 'count' bytes.

Returns 'true' if cache contains resulting position.

Definition at line 106 of file OgreDataStream.h.
