The path separator is always '/'.

This service is defined in library Arp.System.Commons.Services.

Constructor & Destructor Documentation

◆ IFileService()

Arp::System::Commons::Services::Io::IFileService::IFileService ( void )

default

Constructs an IFileService instance.

Member Function Documentation

◆ Copy()

virtual FileSystemError Arp::System::Commons::Services::Io::IFileService::Copy	(	boolean	createDirectory,
		boolean	overwrite,
		const RscString< 512 > &	sourceFilePath,
		const RscString< 512 > &	destinationFilePath
	)

pure virtual

Copies the specified files.

Parameters

createDirectory	if set to `true` the directory of the file is created (recursively), if it does not exists yet.
overwrite	if set to `true` the destination file is overwritten, if it yet exists, otherwise an error is returned.
sourceFilePath	The source path of the file to copy.
destinationFilePath	The destination path of the file to copy.

Returns: Result of the action.

◆ Delete()

virtual FileSystemError Arp::System::Commons::Services::Io::IFileService::Delete ( const RscString< 512 > & filePath )

pure virtual

Deletes the specified file.

Parameters

filePath The pathe of the file to delete.

Returns: Result of the action.

◆ Exists()

virtual boolean Arp::System::Commons::Services::Io::IFileService::Exists ( const RscString< 512 > & path )

pure virtual

Checks if the specified file exists.

Parameters

path	Path of the file to check.

Returns: true if the file exists, otherwise false.

◆ Move()

virtual FileSystemError Arp::System::Commons::Services::Io::IFileService::Move	(	boolean	createDirectory,
		boolean	overwrite,
		const RscString< 512 > &	sourceFilePath,
		const RscString< 512 > &	destinationFilePath
	)

pure virtual

Moves the specified file.

Parameters

createDirectory	if set to `true` the directory of the file is created (recursively), if it does not exists yet.
overwrite	if set to `true` the destination file is overwritten, if it yet exists, otherwise an error is returned.
sourceFilePath	The source path of the file to move.
destinationFilePath	The destination path of the file to move.

Returns: Result of the action.

◆ Read()

virtual FileSystemError Arp::System::Commons::Services::Io::IFileService::Read	(	Traits	fileTraits,
		const RscString< 512 > &	filePath,
		RscStreamAdapter	data,
		std::vector< TraitItem > &	traitItems
	)

pure virtual

Reads the specified file from device.

Parameters

fileTraits	Specifies the file traits to read, if this value is not Arp.System.Commons.Services.Io.Traits.None.
filePath	The path of the file to read.
data	Data read from the specified file.
traitItems	Specified trait items read from the specified file.

Returns: Result of the action.

◆ Write()

virtual FileSystemError Arp::System::Commons::Services::Io::IFileService::Write	(	const RscString< 512 > &	filePath,
		boolean	overwrite,
		const std::vector< TraitItem > &	traitItems,
		RscStreamAdapter	data
	)

pure virtual

Writes the given data to the specified file.

Parameters

filePath	Path of the file on the target.
overwrite	If set to `true` the destination file is overwritten, if it yet exists, otherwise an error is returned.
traitItems	Trait items to set up after writing the file.
data	Data to writing into the specified file.

Returns: Result of the action.
