Detailed Description

a DiskList implementation for the XRD protocol

Constructor & Destructor Documentation

SH::DiskListXRD::DiskListXRD	(	const std::string &	val_server,
		const std::string &	val_dir,
		bool	val_laxParsing = false
	)

make the listing for the given directory, but replacing the directory with prefix for the path

Parameters:

	val_dir	the directory to list
	val_prefix	the prefix with which val_dir will be replaced in the reported paths
	val_laxParsing	if true, graciously skip over any error messages.

Guarantee

strong

Failures

out of memory II

Rationale

this mechanism is meant to allow scanning file servers using one protocol, but then accessing them using another

Member Function Documentation

DiskList * SH::DiskListXRD::doOpenDir

(

)

const [protected, virtual]

make a new list object for the sub-directory

Returns:

a new list object for the sub-directory, or NULL if it is not a directory

Precondition:

(soft) next() has been called successfully

Guarantee

strong

Failures

out of memory III

Rationale

the virtual part of DiskList::openDir()

Implements SH::DiskList.

std::string SH::DiskListXRD::getDirname

(

)

const [protected, virtual]

the base path for the directory listed

Guarantee

strong

Failures

out of memory II

Rationale

the virtual part of DiskList::dirname()

Implements SH::DiskList.

bool SH::DiskListXRD::getNext

(

)

[protected, virtual]

get the next list entry

Returns:

whether we found another entry

Guarantee

basic

Failures

i/o errors

Rationale

the virtual part of DiskList::next()

Implements SH::DiskList.

std::string SH::DiskListXRD::getPath

(

)

const [protected, virtual]

the path for the current entry.

Returns:

the path for the current entry

Precondition:

(soft) next() has been called successfully

Guarantee

strong failures: out of memory III

Rationale

the virtual part of DiskList::path()

Implements SH::DiskList.

void SH::DiskListXRD::testInvariant

(

)

const

test the invariant of this object

Guarantee

no-fail

Reimplemented from SH::DiskList.
