Member Function Documentation

virtual const char* vl::FileSystem::className

(

)

[inline, virtual]

Returns the name of the class.

Reimplemented from vl::Object.

ref< VirtualFile > FileSystem::locateFile	(	const String &	full_path,
		const String &	alternate_path = String()
	)			const [virtual]

Looks for a VirtualFile on the disk and in the currently active FileSystem.

If more than a file exists with the same name the VirtualFile returned is the one found in the VirtualDirectory added the latest.

This means that a VirtualDirectory overrides the ones added before if duplicate file name exists. If a file with the given name exists in the "." directory it will be located and returned immediately.

Visualization Library locates a file scanning the following paths (in the specified order):

• first split full_path into file_path and file_name

• look for the following file paths:
  1. ./file_path/file_name
  2. /fs/file_path/file_name
  3. ./alternate_path/file_path/file_name
  4. /fs/alternate_path/file_path/file_name
  5. ./file_name
  6. /fs/file_name
  7. ./alternate_path/file_name
  8. /fs/alternate_path/file_name

"/fs" stays for Visualization Library currently mounted FileSystems.

ref< VirtualDirectory > FileSystem::locateDirectory

const String &

name

const [virtual]

void FileSystem::listFilesRecursive

(

std::vector< String > &

file_list

)

const [virtual]

Returns the names of all the files contained in the previously added Directories.

Files from different Directories but with the same name appear more than once in 'file_list'. Use carefully this function as it enumerates recursively all the files in the directory trees.

void FileSystem::listFilesRecursive	(	std::vector< String > &	file_list,
		const String &	match
	)			const [virtual]

Returns the names of all the files matching the given filter.

Use carefully this function since it enumerates recursively all the files in the directory trees. The match parameter must be of the type "*abc" or "*abc*" or "abc*".

Collection<VirtualDirectory>* vl::FileSystem::directories

(

)

[inline]

Returns the list of VirtualDirectory objects added to a FileSystem.

const Collection<VirtualDirectory>* vl::FileSystem::directories

(

)

const [inline]

Returns the list of VirtualDirectory objects added to a FileSystem.
