LvaluePropertyMap

LvaluePropertyMap

The LvaluePropertyMap provides an interface for accessing a reference to a property object (instead of a copy of the object as in the get() function required by ReadablePropertyMap). An LvaluePropertyMap can be mutable or non-mutable. The mutable LvaluePropertyMap returns a reference whereas the non-mutable returns a const reference.

Refinement of

ReadablePropertyMap for non-mutable or ReadWritePropertyMap for mutable property map.

Notation

`PMap`	A type that is a model of LvaluePropertyMap.
`pmap`	An object of type `PMap`.
`key`	An object of type `boost::property_traits<PMap>::key_type`.

Associated Types

Property Map Category boost::property_traits<PMap>::category The category of the property: a type convertible to boost::lvalue_property_map_tag.

Valid Expressions
