NAME
Ekahau::Response::LocationEstimate - Contains an estimate of an object's location
SYNOPSIS
When an object is being tracked by Ekahau, you'll receive periodic estimates of its location, in the form of these objects.
DESCRIPTION
Constructor
Generally you will not want to construct these objects yourself; they are created by Ekahau::Response, and use its constructor.
Methods
get_props ( @prop_names )
Inherited from Ekahau::Response::get_props. Returns a hash containing the values for the list of Properties in @prop_names. If @prop_names is empty, all properties will be returned.
get_prop ( $prop_name )
Inherited from Ekahau::Response::get_prop. Returns the value for one of this object's Properties, specified by $prop_name. If no property named $prop_name exists, undef is returned.
type ( )
Returns the string LocationEstimate, to identify the type of this object.
Properties
Properties can be retreived with get_prop or get_props. The list of properties below may not be complete, and not all properties will be available for all objects. Property names are case-sensitive.
accurateX
The X coordinate of the most accurate position information available for the device. The extra accuracy comes at the expense of some additional time to gather and process information, so the information may be slightly older than that available in latestX
accurateY
The X coordinate of the most accurate position information available for the device.
accurateTime
The time of the last accurate position information update.
accurateContextId
The location context of the last accurate position information update.
accurateExpectedError
The expected error of the last accurate position information update, in meters or feet depending on configuration.
latestX
The X coordinate of the latest position information available for the device. The speedy update comes at the expense of some accuracy, so the information may be somewhat inaccurate and jittery. More accurate, but older, information is available in accurateX
latestY
The Y coordinate of the latest position information available for the device.
latestTime
The time of the last position information update.
latestContexId
The location context of the last position information update.
latestExpectedError
The expected error of the last accurate position information update, in meters or feet depending on configuration.
