Method Detail

reload

java.lang.String reload()

Refresh properties and table images. Returns null if successful, else error as String.

sampling

java.lang.String sampling(java.lang.String fieldId,
                          double longitude,
                          double latitude)

Sampling one point Must have local access to layer files and db connection.

Parameters:

fieldId - one field table id for intersection with the coordinates

longitude - longitude as double

latitude - latitude as double

Returns:

value of the intersection as String or null if no value available.

samplingFull

java.util.Vector samplingFull(java.lang.String fieldIds,
                              double longitude,
                              double latitude)

Sampling one point, multiple fields. Full result returned Must have local access to layer files and db connection.

Parameters:

fieldIds - fields to intersect as field table ids in comma separated String. e.g. "cl22,cl23"

longitude - longitude as double

latitude - latitude as double

Returns:

full result of sampling returned as Vector containing one Map for each fieldId. Map objects contain, "fieldid", "value", "layername", and in addition for shape results "pid", "description"

sampling

java.util.ArrayList<java.lang.String> sampling(java.lang.String fieldIds,
                                               java.lang.String pointsString)

Sampling

Parameters:

fieldIds - fields to intersect as field table ids in comma separated String. e.g. "cl22,cl23"

pointsString - latitude,longitude pairs, comma separated. e.g. "-20,120,-23,145"

Returns:

one string for each fieldId, containing new line separated intersection values of the field and pointsString pairs. As ArrayList.

sampling

java.util.ArrayList<java.lang.String> sampling(java.lang.String[] fieldIds,
                                               double[][] points)

Sampling

Parameters:

fieldIds - fields to intersect as field table ids in String [].

points - longitude, latitude coordinates as double [][2]. [][0] is longitude, [][1] is latitude.

Returns:

one string for each fieldId, containing new line separated intersection values of the field and pointsString pairs. As ArrayList.

java.util.ArrayList<java.lang.String> sampling(java.lang.String[] fieldIds,
                                               double[][] points,
                                               IntersectCallback callback)

Sampling

Parameters:

fieldIds - fields to intersect as field table ids in String [].

points - longitude, latitude coordinates as double [][2]. [][0] is longitude, [][1] is latitude.

Returns:

one string for each fieldId, containing new line separated intersection values of the field and pointsString pairs. As ArrayList.

sampling

java.util.ArrayList<java.lang.String> sampling(IntersectionFile[] intersectionFiles,
                                               double[][] points)

Sampling

Parameters:

intersectionFiles - fields to intersect as IntersectionFile []

points - longitude, latitude coordinates as double [][2]. [][0] is longitude, [][1] is latitude.

Returns:

one string for each fieldId, containing new line separated intersection values of the field and pointsString pairs. As ArrayList.

getConfig

IntersectConfig getConfig()

Get initialised IntersectConfig.

Returns:

IntersectConfig

sampling

java.util.HashMap<java.lang.String,java.lang.String> sampling(double longitude,
