INTERFACE

METHODS

new ( [ property=>property_def ] [, value=>valueref ] )

Creates a new property with the CIM property description property_def and a value stored at valueref.

name

Returns the name of the property using the defined case.

value ( [ newvalue ] )

If the newvalue list is specified, sets the value to that. Returns the current mapped value. If the property is an array, and the method is used in a scalar context, the values are join(', ')ed.

raw_value ( [ newvalue ] )

If the newvalue list is specified, sets the value to that. Returns the current unmapped value. If the property is an array, and the method is used in a scalar context, the values are join(', ')ed.

is_array ( property )

Returns a true value equal to the length of the array if the named property is an array or 0 otherwise. A zero-length array returns '0 but true'

is_ref ( property )

Returns true if the named property is a reference or false otherwise.

type ( property )

Returns the type name of the specified property. If the property is an array, will have '[]' appended. For properties which have no type information in the instance, the type is assumed to be 'string'.
