NAME

       Geo::GDAL::FFI::FeatureDefn - A GDAL feature schema

SYNOPSIS

DESCRIPTION

METHODS

   new
        $defn = Geo::GDAL::FFI::FeatureDefn->new({Fields => [...], GeometryType => 'Point'});

       Create a new FeatureDefn object.

       The named arguments (optional) are the following.

       "Name"
           Optional; the name for this feature class; default is the empty string.

       "Fields"
           Optional, a reference to an array of FieldDefn objects or schemas.

       "GeometryFields"
           Optional, a reference to an array of GeomFieldDefn objects or schemas.

       "GeometryType"
           Optional, the type for the first geometry field; default is Unknown. Note that this argument is
           ignored if GeometryFields is given.

       "StyleIgnored"

   GetSchema
       Returns the definition as a perl data structure.

   GetFieldDefn
        my $field_defn = $defn->GetFieldDefn($name);

       Get the specified non spatial field object. If the argument is explicitly an integer and not a string, it
       is taken as the field index.

   GetFieldDefns
        my @field_defns = $defn->GetFieldDefns;

   GetGeomFieldDefn
        my $geom_field_defn = $defn->GetGeomFieldDefn($name);

       Get the specified spatial field object. If the argument is explicitly an integer and not a string, it is
       taken as the field index.

   GetGeomFieldDefns
        my @geom_field_defns = $defn->GetGeomFieldDefns;

   SetGeometryIgnored
        $defn->SetGeometryIgnored($arg);

       Ignore the first geometry field when reading features from a layer. To not ignore the first geometry
       field call this method with defined but false (0) argument.

   IsGeometryIgnored
        my $is = $defn->IsGeometryIgnored;

       Is the first geometry field ignored when reading features from a layer.
