Detailed Description

an implementation of DiskOutput using the XRD protocol

Rationale

this is to be used when storing output n-tuples on xrootd servers

Member Function Documentation

virtual DiskWriter* SH::DiskOutputXRD::doMakeWriter	(	const std::string &	sample,
		const std::string &	name,
		int	index,
		const std::string &	suffix
	)			const [protected, virtual]

create a writer object for a file with the id

Parameters:

	sample	the name of the sample this belongs to
	name	the name of the file to create
	index	the index of the file within the sample, or otherwise -1
	suffix	the suffix to use for the file

Returns:

the writer object

Precondition:

!sample.empty() || !name.empty()

index >= -1

Postcondition:

result != 0

Guarantee

strong

Failures

out of memory II

Failures

i/o errors rationale: you don't need to set all of these, but you need to set at least either the name or the sample.

Rationale

the virtual part of DiskOutput::makeWriter

Reimplemented from SH::DiskOutput.

void SH::DiskOutputXRD::testInvariant

(

)

const

test the invariant of this object

Guarantee

no-fail

Reimplemented from SH::DiskOutput.
