LibGEOS extension

This is the main file for the LibGEOS extension of GeometryOps.

import GeometryOps: GEOS, enforce, True, False, booltype, booltype, WithTrait, TraitTarget

using GeometryOps

The filter statement is required because in Julia, each module has its own versions of these functions, which serve to evaluate or include code inside the scope of the module. However, if you import those from another module (which you would with all=true), that creates an ambiguity which causes a warning during precompile/load time. In order to avoid this, we filter out these special functions.

This is kind of like ImportAll.jl but without the macro. It only imports the functions in names(GeometryOps; all=false).

for name in filter(!in((:var"#eval", :eval, :var"#include", :include)), names(GeometryOps))
    @eval import GeometryOps: $name
end

"""
    _wrap(geom; crs, calc_extent)

Wraps `geom` in a GI wrapper geometry of its geometry trait.  This allows us
to attach CRS and extent info to geometry types which otherwise could not hold
those, like LibGEOS and WKB geometries.

Returns a GI wrapper geometry, for which `parent(result) == geom`.
"""
function _wrap(geom; crs=GI.crs(geom), calc_extent = true)
    return GI.geointerface_geomtype(GI.geomtrait(geom))(geom; crs, extent = GI.extent(geom, calc_extent))
