Detailed Description

an interface that manages writing a single output file

Rationale

This interface allows to write files to arbitrary storage systems. Most importantly, it allows to execute actions after a file has been closed.

Warning:

This interface may still change, if new output types are added that need new functionality.

void SH::DiskWriter::close

(

)

closes the file we are writing to

std::string SH::DiskWriter::path

(

void

)

const

the path where this file can be accessed or the empty string if it is not known (yet).

Rationale

while it is not guaranteed that every writer will know how to handle this, most writers will, and it can be useful. however, not every writer will know this until after the file is closed.

void SH::DiskWriter::testInvariant

(

)

const

test the invariant of this object

Guarantee

no-fail

Reimplemented in SH::DiskWriterLocal, and SH::DiskWriterXRD.
