Method Summary

Modifier and Type	Method and Description
(package private) void	checkAngles(Element track) Verifies that each kml:angles element contained by a Track satisfies the following constraints: (a) it contains a space-delimited list of numeric values; (b) if the track has no associated model, then only one angle (heading) is specified.
(package private) void	checkCoordList(Element track) Verifies that the coordinates specifying the track positions (kml:coord) consist of space-delimited numeric values in the applicable coordinate reference system (default CRS).
String	getErrorMessages() Returns the error messages reported during the last call to isValid.
(package private) double[]	getNumericValues(Node node) Gets the content of the given node as an array of numeric values.
boolean	isValid(Node node) Validates the content of a kml:Track element by checking the constraints defined by the following test cases: ATC-146: Track positions ATC-147: Track properties constitute parallel array ATC-148: Track orientations
void	reset() Resets the error handler.

Method Detail

getErrorMessages

public String getErrorMessages()

Returns the error messages reported during the last call to isValid.

Returns:

A String containing error messages (may be empty).

reset

public void reset()

Resets the error handler.

isValid

public boolean isValid(Node node)

Validates the content of a kml:Track element by checking the constraints defined by the following test cases:

1. ATC-146: Track positions
2. ATC-147: Track properties constitute parallel array
3. ATC-148: Track orientations

Parameters:

node - A kml:Track element.

Returns:

true if the track satisfies all applicable constraints; false otherwise.

checkCoordList

void checkCoordList(Element track)

Verifies that the coordinates specifying the track positions (kml:coord) consist of space-delimited numeric values in the applicable coordinate reference system (default CRS).

Parameters:

track - A kml:Track element

See Also:

"OGC 14-068r1: OGC KML 2.3 - Abstract Test Suite, ATC-146"

checkAngles

void checkAngles(Element track)

Verifies that each kml:angles element contained by a Track satisfies the following constraints: (a) it contains a space-delimited list of numeric values; (b) if the track has no associated model, then only one angle (heading) is specified.

Parameters:

track - A kml:Track element

See Also:

"OGC 14-068r1: OGC KML 2.3 - Abstract Test Suite, ATC-148"

getNumericValues

double[] getNumericValues(Node node)

Gets the content of the given node as an array of numeric values.

Parameters:

node - A node containing a sequence of space-separated values, all of which are presumed to be a parsable double.

Returns:

A double[] array.
