Member Function Documentation

Available()

bool opendal::Operator::Available

(

)

const

Check if the operator is available.

Returns

true if the operator is available, false otherwise

Copy()

void opendal::Operator::Copy	(	std::string_view	src,
		std::string_view	dst
	)

Copy a file from src to dst.

Parameters

src	The source path
dst	The destination path

CreateDir()

void opendal::Operator::CreateDir

(

std::string_view

path

)

Create a directory.

Parameters

path	The path of the directory

Exists()

bool opendal::Operator::Exists

(

std::string_view

path

)

Check if the path exists.

Parameters

path	The path to check

Returns

true if the path exists, false otherwise

GetLister()

Lister opendal::Operator::GetLister

(

std::string_view

path

)

GetReader()

Reader opendal::Operator::GetReader

(

std::string_view

path

)

Read data from the operator.

Parameters

path	The path of the data

Returns

The reader of the data

Info()

Capability opendal::Operator::Info

(

)

IsExist()

bool opendal::Operator::IsExist

(

std::string_view

path

)

Check if the path exists.

Parameters

path	The path to check

Returns

true if the path exists, false otherwise

List()

std::vector< Entry > opendal::Operator::List

(

std::string_view

path

)

List the entries of a directory.

Note

The returned entries are sorted by name.

Parameters

path	The path of the directory

Returns

The entries of the directory

operator=() [1/2]

Operator & opendal::Operator::operator= ( const Operator &  )

delete

operator=() [2/2]

Operator & opendal::Operator::operator= ( Operator &&  other )

noexcept

Read()

std::string opendal::Operator::Read

(

std::string_view

path

)

Read data from the operator.

Note

The operation will make unnecessary copy. So we recommend to use the GetReader method.

Parameters

path	The path of the data

Returns

The data read from the operator

Remove()

void opendal::Operator::Remove

(

std::string_view

path

)

Remove a file or directory.

Parameters

path	The path of the file or directory

Rename()

void opendal::Operator::Rename	(	std::string_view	src,
		std::string_view	dst
	)

Rename a file from src to dst.

Parameters

src	The source path
dst	The destination path

Stat()

Metadata opendal::Operator::Stat

(

std::string_view

path

)

Get the metadata of a file or directory.

Parameters

path	The path of the file or directory

Returns

The metadata of the file or directory

Write()

void opendal::Operator::Write	(	std::string_view	path,
		std::string_view	data
	)

Write data to the operator.

Parameters

path	The path of the data
data	The data to write
