Member Function Documentation

AddCachePathToFilename()

const char* vtkCacheManager::AddCachePathToFilename

(

const char *

filename

)

CachedFileExists()

virtual int vtkCacheManager::CachedFileExists ( const char *  filename )

virtual

Checks to see if the The uri provided exists on disk. If not, it appends the Remote Cache Directory path and checks again, in case no path was provided. If neither exists, returns 0. If one exists, returns 1.

CacheSizeCheck()

void vtkCacheManager::CacheSizeCheck

(

)

ClearCache()

int vtkCacheManager::ClearCache

(

)

Removes all files from the cachedir and removes all filenames from CachedFileList

ClearCacheCheck()

int vtkCacheManager::ClearCacheCheck

(

)

This method is called after ClearCache(), to see if that method actually cleaned the cache. If not, an event (CacheDirtyEvent) is invoked.

ComputeCacheSize()

float vtkCacheManager::ComputeCacheSize	(	const char *	dirname,
		unsigned long	size
	)

DeleteFromCache()

void vtkCacheManager::DeleteFromCache

(

const char *

target

)

Remove a target directory or file from the cache.

DeleteFromCachedFileList()

void vtkCacheManager::DeleteFromCachedFileList

(

const char *

target

)

Removes a target from the list of locally cached files and directories.

EncodeURI()

const char* vtkCacheManager::EncodeURI

(

const char *

uri

)

FindCachedFile()

const char* vtkCacheManager::FindCachedFile	(	const char *	target,
		const char *	dirname
	)

Takes a filename and a dirname (usually called with the RemoteCachedDirectory) and returns the full path of the filename if it exists under the dirname.

FreeCacheBufferCheck()

void vtkCacheManager::FreeCacheBufferCheck

(

)

GetCachedFiles()

std::vector< std::string > vtkCacheManager::GetCachedFiles

(

)

const

GetClassName()

virtual const char* vtkCacheManager::GetClassName ( )

virtual

GetCurrentCacheSize()

float vtkCacheManager::GetCurrentCacheSize

(

)

GetEnableForceRedownload()

virtual int vtkCacheManager::GetEnableForceRedownload ( )

virtual

GetFileFromURIMap()

const char* vtkCacheManager::GetFileFromURIMap

(

const char *

uri

)

GetFilenameFromURI()

const char* vtkCacheManager::GetFilenameFromURI

(

const char *

uri

)

Extracts the filename from the URI and prepends the Remote Cache Directory path to it. Returns the full path. NOTE: this method looks at a filename's extension and if appended version numbers have been added, it attempts to strip them out of the extension and add them to the filenamebase. So filename.nrrd_010 would become filename.nrrd. This will cause problems for any file type with an '_' in its extension.

GetFreeCacheSpaceRemaining()

float vtkCacheManager::GetFreeCacheSpaceRemaining

(

)

GetInsufficientFreeBufferNotificationFlag()

virtual int vtkCacheManager::GetInsufficientFreeBufferNotificationFlag ( )

virtual

GetRemoteCacheDirectory()

const char* vtkCacheManager::GetRemoteCacheDirectory

(

)

Returns the name of the directory to use for local file caching.

GetRemoteCacheFreeBufferSize()

virtual int vtkCacheManager::GetRemoteCacheFreeBufferSize ( )

virtual

GetRemoteCacheLimit()

virtual int vtkCacheManager::GetRemoteCacheLimit ( )

virtual

IsA()

virtual int vtkCacheManager::IsA ( const char *  type )

virtual

IsLocalReference()

virtual int vtkCacheManager::IsLocalReference ( const char *  uri )

virtual

Looks for a 'file://' in the uri and if present, returns true.

IsRemoteReference()

virtual int vtkCacheManager::IsRemoteReference ( const char *  uri )

virtual

Checks to see if a uri appears to point to remote location and returns true if so. Looks for a '://' and if present, checks to see if the prefix is 'file'. If not 'file' but the thing:/// pattern exists, then returns true.

IsTypeOf()

static int vtkCacheManager::IsTypeOf ( const char *  type )

static

LocalFileExists()

virtual int vtkCacheManager::LocalFileExists ( const char *  uri )

virtual

Checks to see if a uri is a file on disk and returns true if so. Strips off a file:/// prefix if present, and expects an absolute path.

MapFileToURI()

void vtkCacheManager::MapFileToURI	(	const char *	uri,
		const char *	fname
	)

MarkNode()

void vtkCacheManager::MarkNode

(

std::string

)

MarkNodesBeforeDeletingDataFromCache()

void vtkCacheManager::MarkNodesBeforeDeletingDataFromCache

(

const char *

)

Before a file or directory is deleted, Marks any nodes that hold the uri as a reference as modified since read.

New()

static vtkCacheManager* vtkCacheManager::New ( )

static

The Usual vtk class functions.

operator=()

void vtkCacheManager::operator= ( const vtkCacheManager &  )

protected

PrintSelf()

void vtkCacheManager::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

SafeDownCast()

static vtkCacheManager* vtkCacheManager::SafeDownCast ( vtkObject *  o )

static

SetCurrentCacheSize()

virtual void vtkCacheManager::SetCurrentCacheSize ( float  )

virtual

SetEnableForceRedownload()

virtual void vtkCacheManager::SetEnableForceRedownload ( int  )

virtual

SetInsufficientFreeBufferNotificationFlag()

virtual void vtkCacheManager::SetInsufficientFreeBufferNotificationFlag ( int  )

virtual

SetMRMLScene()

void vtkCacheManager::SetMRMLScene ( vtkMRMLScene *  scene )

inline

Definition at line 129 of file vtkCacheManager.h.

SetRemoteCacheDirectory()

virtual void vtkCacheManager::SetRemoteCacheDirectory ( const char *  dir )

virtual

Sets the name of the directory to use for local file caching Does some checking to make sure this is a valid directory on the local system. Makes sure there's NO "/" at the end of the string, or kwsys/SystemTools will not see as a valid dir.

SetRemoteCacheFreeBufferSize()

virtual void vtkCacheManager::SetRemoteCacheFreeBufferSize ( int  )

virtual

SetRemoteCacheLimit()

virtual void vtkCacheManager::SetRemoteCacheLimit ( int  )

virtual

UpdateCacheInformation()

void vtkCacheManager::UpdateCacheInformation

(

)

Called when a file is loaded or removed from the cache.
