Detailed Description

template<>
class OpenMS::FASTAContainer< TFI_Vector >

FASTAContainer<TFI_Vector> simply takes an existing vector of FASTAEntries and provides the same interface with a potentially huge speed benefit over FASTAContainer<TFI_File> since it does not need disk access, but at the cost of memory.

Constructor & Destructor Documentation

FASTAContainer() [1/2]

FASTAContainer ( )

delete

FASTAContainer() [2/2]

FASTAContainer ( const std::vector< FASTAFile::FASTAEntry > &  data )

inline

C'tor for already existing data (by reference).

An internal reference will be kept. Make sure the data is not deleted during the lifetime of FASTAContainer

Member Function Documentation

activateCache()

bool activateCache ( )

inline

no-op (since data is already fully available as vector)

Returns

true only on the first call; false on subsequent calls

cacheChunk()

bool cacheChunk ( int  )

inline

no-op (since data is already fully available as vector)

Returns

true only on the first call; false on subsequent calls

chunkAt()

const FASTAFile::FASTAEntry& chunkAt ( size_t  pos ) const

inline

fast access to chunked (i.e. all) entries

chunkSize()

size_t chunkSize ( ) const

inline

active data spans the full range, i.e. size of container

Returns

the size of the underlying vector

empty()

bool empty ( ) const

inline

calls empty() on underlying vector

getChunkOffset()

size_t getChunkOffset ( ) const

inline

always 0, since this specialization requires/supports no chunking

readAt()

bool readAt ( FASTAFile::FASTAEntry &  protein, size_t  pos  ) const

inline

fast access to an entry

reset()

void reset ( )

inline

required for template parameters!

size()

size_t size ( ) const

inline

calls size() on underlying vector
