Detailed Description

an implementation of DiskOutput using the XRD protocol

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

Constructor & Destructor Documentation

◆ DiskOutputXRD() [1/2]

SH::DiskOutputXRD::DiskOutputXRD ( )

standard default constructor

Guarantee: strong

Failures: out of memory I

Warning: this is only to be used for the root streaming mechanism, not by the end user

◆ DiskOutputXRD() [2/2]

SH::DiskOutputXRD::DiskOutputXRD ( const std::string & val_prefix )

explicit

standard constructor

Guarantee: strong

Failures: out of memory II

Precondition: val_prefix.find ("root://") == 0

◆ doMakeWriter()

virtual std::unique_ptr< DiskWriter > SH::DiskOutputXRD::doMakeWriter	(	const std::string &	sampleName,
		const std::string &	segmentName,
		const std::string &	suffix ) const

protectedvirtual

create a DiskWriter object managing an output file

Precondition: !sampleName.empty()

Postcondition: result != nullptr

Guarantee: strong

Failures: out of memory II
i/o errors

Rationale: the virtual part of DiskOutput::makeWriter

Implements SH::DiskOutput.

◆ getTargetURL()

virtual std::string SH::DiskOutputXRD::getTargetURL	(	const std::string &	sampleName,
		const std::string &	segmentName,
		const std::string &	suffix ) const

protectedvirtual

Rationale: the virtual part of DiskOutput::targetURL

Implements SH::DiskOutput.

◆ makeWriter()

std::unique_ptr< DiskWriter > SH::DiskOutput::makeWriter	(	const std::string &	sampleName,
		const std::string &	segmentName,
		const std::string &	suffix ) const

inherited

create a DiskWriter object managing an output file

Precondition: !sampleName.empty()

Postcondition: result != nullptr

Guarantee: strong

Failures: out of memory II
i/o errors

◆ targetURL()

std::string SH::DiskOutput::targetURL	(	const std::string &	sampleName,
		const std::string &	segmentName,
		const std::string &	suffix ) const

inherited

the final output location for the given segment

Precondition: !sampleName.empty()

Postcondition: !result.empty()

Guarantee: strong

Failures: out of memory II

◆ testInvariant()

void SH::DiskOutputXRD::testInvariant ( ) const

test the invariant of this object

Guarantee: no-fail
