Member Function Documentation

YCPList SnapperAgent::Dir

(

const YCPPath &

path

)

[virtual]

Provides SCR Dir ().

Dir

Implements SCRAgent.

References y2error.

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)

Reimplemented from SCRAgent.

References getIntValue(), getListValue(), getValue(), YCPElement::isNull(), PC, sh, YCPList::size(), snapper_error, snapper_initialized, YCPList::value(), y2debug, y2error, and y2milestone.

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

References YCPElement::isNull(), and YCPMap::value().

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

References YCPElement::isNull(), and YCPMap::value().

Referenced by Execute().

YCPValue SnapperAgent::otherCommand

(

const YCPTerm &

term

)

[virtual]

Used for mounting the agent.

otherCommand

Reimplemented from SCRAgent.

References YCPTerm::name().

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.

Implements SCRAgent.

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

Provides SCR Write ().

Write

Implements SCRAgent.
