LayerIntersectDAOImpl

public LayerIntersectDAOImpl()

Method Detail

reload

public java.lang.String reload()

Description copied from interface: LayerIntersectDAO

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

Specified by:

reload in interface LayerIntersectDAO

samplingFull

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

Description copied from interface: LayerIntersectDAO

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

Specified by:

samplingFull in interface LayerIntersectDAO

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

public java.lang.String sampling(java.lang.String fieldIds,
                                 double longitude,
                                 double latitude)

Single coordinate sampling.

Specified by:

sampling in interface LayerIntersectDAO

Parameters:

fieldIds - comma separated field ids.

longitude -

latitude -

Returns:

the intersection value for each input field id as a \n separated String.

sampling

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

Description copied from interface: LayerIntersectDAO

Sampling one point, all cached fields. Must have local access to layer files and db connection.

Specified by:

sampling in interface LayerIntersectDAO

Parameters:

longitude - longitude as double

latitude - latitude as double

Returns:

full result of sampling returned as Map with key as field id and value String or Float

sampling

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