By doing the type check before the intersection check, we can
save he intersection check for cases where we don't care about
type or have the specified type in a node.
This is a follow-up for https://github.com/openlayers/ol3/pull/711
for the GML parser. Also use goog.array.map instead of map as was
pointed out by @twpayne on the WKT review and update the example data
to use all US states as pointed out by @tschaub on the Google hangout.
On servers that report an incorrect content type for XML
documents, responseXML will be empty. In these cases we need to
use responseText instead. This change also prevents readNode
calls with empty data.
Add a parser (read/write) for OGC Well-Known-Text (WKT). It deals with
geometries only, not with features, mostly because WKT can only contain a
single geometry (or geometry collection). This can later on be used to
serialize and deserialize geometries in ol3.
The reason for this change is that symbolSizes and maxSymbolSize
on the instance will be wrong as soon as the resolution changes
and cached tiles are used. It turned out that the approach used
now has several advantages: smaller symbolSizes objects, no need
to merge symbolSizes objects, and cache management for free (no
risk of memory leaks). Note that the symbolSizes and
maxSymbolSize for each tile are not strictly tile specific -
they represent the rendering pass that created the tile. This
has no negative side effects, and it has the advantage that
there is not a single additional loop needed to create these
structures.
With this change, hit detection for lines and points gets very
accurate, because the vector renderer instance keeps track of
line widths and point symbol sizes. After doing a bbox query in
the RTree, returned lines and points are evaluated against the
thresholds of their line width or symbol size. The KML example
with its different symbolizers now has getFeatureInfo too to
show this in action.
This adds a parser (read/write) for GML v2 and v3. GML v3 is limited to the
simple features profile of GML 3.1.1, just like OpenLayers 2 was. This will
be the basis for the WFS parser, but it only makes sense to continue this work
once feature modification (insert, update, delete) is in place in ol3. So the
WFS parser will be another pull request.
Without this we get the following warning from the compiler:
JSC_EXPORTED_FUNCTION_UNKNOWN_RETURN_TYPE. Unable to determine return type for exported function ol.control.Control.prototype.handleMapPostrender at ../src/ol/control/control.js line 79 : 51
I'm not sure why explicitely specifying the return type is required here.
If we use ol.control.Control.prototype.handleMapPostrender = goog.nullFunction the API doc doesn't show the mapEvent parameter of the handleMapPostRender function.
