Detailed Description

An abstract interface for writing policy data to streams

Definition at line 47 of file PolicyWriter.h.

Constructor & Destructor Documentation

lsst::pex.policy::PolicyWriter::PolicyWriter ( std::ostream * out = 0 )

create a writer attached to an output stream. If no stream is provided, it will write policy data to an internal string stream; toString() can be used to retrieve the results.

Parameters

out	the output stream to write data to

lsst::pex.policy::PolicyWriter::PolicyWriter	(	const std::string &	file,
		bool	append = `false`
	)

create a writer attached to a file. This file will be immediately opened for writing.

Parameters

file	the path to the output file
append	if true, open the file to append. (default is false.)

virtual lsst::pex.policy::PolicyWriter::~PolicyWriter ( )

virtual

delete this writer

Member Function Documentation

void lsst::pex.policy::PolicyWriter::close ( )

close the output stream. This has no effect if the attached stream is not a file stream.

std::string lsst::pex.policy::PolicyWriter::toString ( )

return the written data as a string. This string will be non-empty only if this class was was instantiated without an attached stream.

virtual void lsst::pex.policy::PolicyWriter::write	(	const Policy &	policy,
		bool	doDecl = `false`
	)

virtual

write the contents of a policy the attached stream. Each top-level parameter will be recursively printed.

Parameters

policy	the policy data to write
doDecl	if true, precede the data with the appropriate file format type.

virtual void lsst::pex.policy::PolicyWriter::writeBool	(	const std::string &	name,
		bool	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
value	the value to save under that name.

virtual void lsst::pex.policy::PolicyWriter::writeBools	(	const std::string &	name,
		const Policy::BoolArray &	values
	)

pure virtual

write an array of property values with a given name

Parameters

name	the name to save the values as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
values	the values to save under that name.

Implemented in lsst::pex.policy::paf::PAFWriter.

virtual void lsst::pex.policy::PolicyWriter::writeDouble	(	const std::string &	name,
		double	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
value	the value to save under that name.

virtual void lsst::pex.policy::PolicyWriter::writeDoubles	(	const std::string &	name,
		const Policy::DoubleArray &	values
	)

pure virtual

write an array of property values with a given name

Parameters

name	the name to save the values as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
values	the values to save under that name.

Implemented in lsst::pex.policy::paf::PAFWriter.

virtual void lsst::pex.policy::PolicyWriter::writeFile	(	const std::string &	name,
		const PolicyFile &	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
value	the value to save under that name.

virtual void lsst::pex.policy::PolicyWriter::writeFiles	(	const std::string &	name,
		const Policy::FilePtrArray &	values
	)

pure virtual

write an array of property values with a given name

Parameters

name	the name to save the values as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
values	the values to save under that name.

Implemented in lsst::pex.policy::paf::PAFWriter.

virtual void lsst::pex.policy::PolicyWriter::writeInt	(	const std::string &	name,
		int	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
value	the value to save under that name.

virtual void lsst::pex.policy::PolicyWriter::writeInts	(	const std::string &	name,
		const Policy::IntArray &	values
	)

pure virtual

write an array of property values with a given name

Parameters

name	the name to save the values as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
values	the values to save under that name.

Implemented in lsst::pex.policy::paf::PAFWriter.

virtual void lsst::pex.policy::PolicyWriter::writePolicies	(	const std::string &	name,
		const Policy::PolicyPtrArray &	values
	)

pure virtual

write an array of property values with a given name

Parameters

name	the name to save the values as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
values	the values to save under that name.

Implemented in lsst::pex.policy::paf::PAFWriter.

virtual void lsst::pex.policy::PolicyWriter::writePolicy	(	const std::string &	name,
		const Policy &	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
value	the value to save under that name.

virtual void lsst::pex.policy::PolicyWriter::writeString	(	const std::string &	name,
		const std::string &	value
	)

virtual

write the given property out as policy data

Parameters

name	the name to save the property as. This may be a hierarchical name; however, an implementation is not guaranteed to support it. If it cannot, it should raise an exception.
