Dataset¶

class caris.Dataset¶

The dataset.

commit((Dataset)self) → None :¶

Commit any changes to the dataset

create_feature((Dataset)self, (str)feature_code, (Geometry)geometry[, (object)attributes=None]) → Feature :¶

Create a new feature

Parameters

• feature_code (str) – The type of feature to create

• geometry (Geometry) – The geometry

• attributes (AttributeDictionary, optional) – The attributes

Returns

A Feature object

delete_feature((Dataset)self, (Feature)feature) → None :¶

Delete an existing feature

Parameters

feature (Feature) – The feature to delete

query((Dataset)self, (str)feature_code[, (object)CQL=None[, (object)contains=None[, (object)crosses=None[, (object)intersects=None[, (object)disjoint_from=None[, (object)equal_to=None[, (object)within=None[, (object)overlaps=None[, (object)touches=None]]]]]]]]]) → FeatureRange :¶

Query for specific features

Parameters

• feature_code (str) – The feature type to return

• CQL (str) – The CQL query to run

• contains (Geometry, optional) – Get Features that completely contain the Geometry without touching. Opposite of within

• crosses (Geometry, optional) – Get Features that have some interior points in common with Geometry, and the dimension of their intersection is less than that of at least one of them

• intersects (Geometry, optional) – Get Features that have at least one point in common with Geometry. Opposite of disjoint_from

• disjoint_from (Geometry, optional) – Get Features that have no points in common with Geometry. Opposite of intersects

• equal_to (Geometry, optional) – Get Features that are topologically equal to Geometry.

• within (Geometry, optional) – Get Features that are completely within Geometry without touching. Opposite of contains

• overlaps (Geometry, optional) – Get Features that have some but not all points in common with Geometry and that have the same dimension. The intersection of Feature and Geometry must have the same dimension as the geometries themselves

• touches (Geometry, optional) – Get Features that have at least one boundary point in common with Geometry, but no interior points

Returns

A FeatureRange with the features returned from the query

query_all((Dataset)self) → FeatureRange :¶

Query all features

Returns

Returns all Features

query_all_deleted((Dataset)self) → FeatureRange :¶

Query all deleted features

Returns

Returns all deleted Features

query_deleted((Dataset)self, (str)feature_code[, (object)CQL=None[, (object)contains=None[, (object)crosses=None[, (object)intersects=None[, (object)disjoint_from=None[, (object)equal_to=None[, (object)within=None[, (object)overlaps=None[, (object)touches=None]]]]]]]]]) → FeatureRange :¶

Query the deleted features

Parameters

• feature_code (str) – The feature type to return

• CQL (str) – The CQL query to run

• contains (Geometry, optional) – Get Features that completely contain the Geometry without touching. Opposite of within

• crosses (Geometry, optional) – Get Features that have some interior points in common with Geometry, and the dimension of their intersection is less than that of at least one of them

• intersects (Geometry, optional) – Get Features that have at least one point in common with Geometry. Opposite of disjoint_from

• disjoint_from (Geometry, optional) – Get Features that have no points in common with Geometry. Opposite of intersects

• equal_to (Geometry, optional) – Get Features that are topologically equal to Geometry.

• within (Geometry, optional) – Get Features that are completely within Geometry without touching. Opposite of contains

• overlaps (Geometry, optional) – Get Features that have some but not all points in common with Geometry and that have the same dimension. The intersection of Feature and Geometry must have the same dimension as the geometries themselves

• touches (Geometry, optional) – Get Features that have at least one boundary point in common with Geometry, but no interior points

Returns

A FeatureRange with the features returned from the query

rollback((Dataset)self) → None :¶

Rollback any changes to the dataset
