inline

MemoryNode constructor.

Parameters

[in] path full path to this node.

Definition at line 381 of file file_system.h.

Member Function Documentation

◆ copy_file()

bool GEO::FileSystem::MemoryNode::copy_file	(	const std::string &	from,
		const std::string &	to
	)

overridevirtual

Copies a file.

Parameters

[in]	from	name of the file to be copied
[out]	to	name of the copy

Return values

true	if the copy was successful
false	otherwise

Reimplemented from GEO::FileSystem::Node.

◆ create_directory()

virtual bool GEO::FileSystem::MemoryNode::create_directory ( const std::string & path )

overridevirtual

Creates a directory.

This recursively creates a new directory given by its absolute path path, creating any missing intermediate directories on the fly.

Parameters

[in] path absolute path to the directory to be created.

Return values

true	if the directory was successfully created.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ create_file()

bool GEO::FileSystem::MemoryNode::create_file	(	const std::string &	path,
		const char *	content
	)

Creates a file.

Parameters

[in]	path	the path to the file
[in]	content	a const pointer to the contents of the file

◆ delete_directory()

virtual bool GEO::FileSystem::MemoryNode::delete_directory ( const std::string & path )

overridevirtual

Deletes a directory.

This deletes the directory specified by path path. The path must specify an empty directory.

Parameters

[in] path the path of the directory to be removed.

Return values

true	if the directory was successfully deleted.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ delete_file()

virtual bool GEO::FileSystem::MemoryNode::delete_file ( const std::string & path )

overridevirtual

Deletes a file.

Parameters

[in] path the path of the file to be deleted.

Return values

true	if the file path was successfully deleted
false	otherwise

Reimplemented from GEO::FileSystem::Node.

◆ get_directory_entries()

bool GEO::FileSystem::MemoryNode::get_directory_entries	(	const std::string &	path,
		std::vector< std::string > &	result
	)

overridevirtual

Lists directory contents.

Lists all the files and sub-directories in the directory specified by path, and stores the list in result. Special entries "." and ".." are not stored in result.

Parameters

[in]	path	the path to the directory to list.
[in]	result	output vector of files and sub-directories.

Return values

true	if `path` specifies a readable directory.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ get_file_contents()

const char * GEO::FileSystem::MemoryNode::get_file_contents ( const std::string & path )

Gets the contents of a file.

Parameters

[in] path the path to the file.

Returns: a const pointer to the contents of the file.

◆ is_directory()

virtual bool GEO::FileSystem::MemoryNode::is_directory ( const std::string & path )

overridevirtual

Checks if a path is a directory.

Parameters

[in] path system path to verify.

Return values

true	if `path` is a directory.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ is_file()

virtual bool GEO::FileSystem::MemoryNode::is_file ( const std::string & path )

overridevirtual

Checks if a path is a regular file.

Parameters

[in] path system path to verify.

Return values

true	if `path` is a regular file.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ load_file_as_string()

std::string GEO::FileSystem::MemoryNode::load_file_as_string ( const std::string & path )

overridevirtual

Load file contents in a string.

Parameters

[in] path the path to the file

Returns: a string with the contents of the file.

Reimplemented from GEO::FileSystem::Node.

◆ rename_file()

bool GEO::FileSystem::MemoryNode::rename_file	(	const std::string &	old_name,
		const std::string &	new_name
	)

overridevirtual

Renames or moves a file.

This renames the existing file or directory specified by path old_name to the new path new_name. The new name must not be the name of an existing file or directory. If old_name and new_name are not in the same directory, old_name is moved to the new_name.

Parameters

[in]	old_name	path of the file or directory to be renamed.
[in]	new_name	new path of the file or directory.

Return values

true	if the file was renamed successfully.
false	otherwise.

Reimplemented from GEO::FileSystem::Node.

◆ split_path()

static void GEO::FileSystem::MemoryNode::split_path	(	const std::string &	path,
		std::string &	leadingsubdir,
		std::string &	rest
	)

staticprotected

Splits a path.

Parameters

[in]	path	the path
[out]	leadingsubdir	the leading subdirectory or the empty string
[out]	rest	the rest of the path
