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.
