Member Function Documentation

YCPList SnapperAgent::Dir ( const YCPPath & path )

virtual

Provides SCR Dir ().

Dir

YCPValue SnapperAgent::Execute	(	const YCPPath &	path,
		const YCPValue &	arg = `YCPNull()`,
		const YCPValue &	arg2 = `YCPNull()`
	)

virtual

Provides SCR Execute ().

Execute

Execute (.snapper) call: Initialize snapper object

Rollback the list of given files from snapshot num1 to num2 (system by default)

References getIntValue(), getListValue(), getValue(), PC, sh, snapper_error, and snapper_initialized.

int SnapperAgent::getIntValue	(	const YCPMap &	map,
		const YCPString &	key,
		const int	deflt
	)

private

Search the map for value of given key

Parameters:

map	YCP Map to look in
key	key we are looking for
deflt	the default value to be returned if key is not found

Referenced by Execute(), and Read().

YCPList SnapperAgent::getListValue	(	const YCPMap &	map,
		const YCPString &	key
	)

private

Search the map for value of given key; key is string and value is YCPList

Referenced by Execute().

string SnapperAgent::getValue	(	const YCPMap &	map,
		const YCPString &	key,
		const string &	deflt
	)

private

search the map for value of given key; both key and value have to be strings when key is not present, default value is returned

Referenced by Execute().

YCPValue SnapperAgent::otherCommand ( const YCPTerm & term )

virtual

Used for mounting the agent.

otherCommand

YCPValue SnapperAgent::Read	(	const YCPPath &	path,
		const YCPValue &	arg = `YCPNull()`,
		const YCPValue &	opt = `YCPNull()`
	)

virtual

Provides SCR Read ().

Parameters:

path	Path that should be read.
arg	Additional parameter.

Read

Read (.snapper.error) -> returns last error message

Read (.snapper.path, $[ "num" : num]) -> returns the path to directory with given snapshot

Read(.snapper.snapshots) -> return list of snapshot description maps

Read(.snapper.diff_list) -> show difference between snapnots num1 and num2 as list.

Read(.snapper.diff_index) -> show difference between snapnots num1 and num2 as one-level map: (mapping each file to its changes)

Read(.snapper.diff_tree) -> show difference between snapnots num1 and num2 as tree.

YCPBoolean SnapperAgent::Write	(	const YCPPath &	path,
		const YCPValue &	arg,
		const YCPValue &	arg2 = `YCPNull()`
	)

virtual

Provides SCR Write ().
