Detailed Description

Class for storing generic metadata.

This class stores key/value pairs, like a Python dictionary but in C++. Keys are always C++ strings. Values can be C++ primitive data types, strings, lsst::daf::base::DateTime objects, and lsst::daf::base::Persistable subclasses (although the latter is currently discouraged). Values can also be vectors of these items.

PropertySets are hierarchical; values within a PropertySet that is contained within another PropertySet can be addressed using dotted paths ("a.b.c"). If "flat=true" is specified to the constructor, the PropertySet still takes dotted paths but is not actually hierarchical in structure. This is used to support PropertyList.

Replace all values for a property name (possibly hierarchical) with a string value.

Parameters

[in]	name	Property name to set, possibly hierarchical.

std::string lsst::daf::base::PropertySet::toString	(	bool	topLevelOnly = `false`,
		std::string const &	indent = `""`
	)		const

virtual

Generate a string representation of the PropertySet. Use this for debugging, not for serialization/persistence.

Parameters

[in]	topLevelOnly	false (default) = do include subproperties.
[in]	indent	String to indent lines by (default none).

Returns: String representation of the PropertySet.
