Detailed Description

This module defines an implementation of Sample that contains composite samples.

Warning:

This class hasn't been maintained in a long time and probably has never been fully functional in the first place.

standard constructor

Guarantee

strong

Failures

out of memory I

Warning:

only to be used by serialization code

Member Function Documentation

void SH::SampleComposite::add

(

const SamplePtr &

sample

)

add a sample to the list

Guarantee

strong

Failures

low level errors II
sample contains this sample

Precondition:

!sample.empty()

virtual void SH::SampleComposite::doAddSamples

(

SampleHandler &

result

)

[protected, virtual]

add all samples this sample corresponds to to the given sample handler

Guarantee

basic, may only add some

Failures

out of memory II

Rationale this is used with composite samples to find the

actual list of samples to run on.

Rationale

the virtual part of SH::Sample::addSamples()

Reimplemented from SH::Sample.

virtual std::vector<std::string> SH::SampleComposite::doMakeFileList

(

)

const [protected, virtual]

make a list of all files, prestaging them if necessary

Guarantee

basic

Failures

out of memory III
file catalogue failures
prestaging failures

Rationale

the virtual part of Sample::makeFileList

Implements SH::Sample.

virtual SamplePtr SH::SampleComposite::doMakeLocal

(

)

const [protected, virtual]

Make this a local sample, i.e. one which can be directly opened with TFile::Open.

Returns:

the local sample, or "this" if this already is a local sample

Guarantee

strong

Failures

out of memory III
can not make local sample

Rationale

the virtual part of SH::Sample::makeLocal()

Implements SH::Sample.

virtual void SH::SampleComposite::doUpdateLocation	(	const std::string &	from,
		const std::string &	to
	)			[protected, virtual]

update all file references starting with from to to

Parameters:

	from	the original path to the data area
	to	the new path to the data area

Guarantee

basic, may update partially

Failures

out of memory II

Precondition:

!from.empty()

Postcondition:

!to.empty()

Rationale

this is needed when moving data around without recreating the samples from scratch

Rationale

the virtual part of SH::Sample::updateLocation()

Reimplemented from SH::Sample.

virtual bool SH::SampleComposite::getContains

(

const std::string &

name

)

const [protected, virtual]

whether this sample contains a sample of the given name

Returns:

whether this sample contains a sample of the given name (or whether the sample itself has the given name)

Guarantee

no-fail

Rationale

this is used with composite sample to make sure we don't create ring like structures that would lead to endless recursion. the reason to check by name, not by address is that we will probably want to add these samples to a sample handler at some point.

Rationale

the virtual part of SH::Sample::contains()

Reimplemented from SH::Sample.

virtual std::string SH::SampleComposite::getFileName

(

std::size_t

index

)

const [protected, virtual]

the name of the file with the given index

Parameters:

index

the index of the file

Guarantee

no-fail

Precondition:

index < numFiles()

Postcondition:

!result.empty()

Warning:

this is meant more for debugging and may or may not do what you want, e.g. if this is a grid dataset the file may not be directly accessible.

Rationale

the virtual part of Sample::fileName()

Implements SH::Sample.

virtual std::size_t SH::SampleComposite::getNumFiles

(

)

const [protected, virtual]

the number of files in the sample

Guarantee

no-fail

Rationale

the virtual part of Sample::numFiles()

Implements SH::Sample.

void SH::SampleComposite::testInvariant

(

)

const

test the invariant of this object

Guarantee

no-fail

Reimplemented from SH::Sample.
