resqpy.strata.StratigraphicColumn¶

class resqpy.strata.StratigraphicColumn(parent_model, uuid=None, rank_uuid_list=None, title=None, extra_metadata=None)¶

Bases: BaseResqpy

Class for RESQML stratigraphic column objects.

RESQML documentation:

A global interpretation of the stratigraphy, which can be made up of several ranks of stratigraphic unit interpretations.

All stratigraphic column rank interpretations that make up a stratigraphic column must be ordered by age.

Public Data Attributes:

resqml_type

Inherited from BaseResqpy

`resqml_type`
`part`	Standard part name corresponding to self.uuid.
`root`	XML node corresponding to self.uuid.
`citation_title`	Citation block title equivalent to self.title.

Methods:

`__init__`(parent_model[, uuid, ...])	Initialises a Stratigraphic Column object.
`iter_ranks`()	Yields the stratigraphic column ranks which constitute this stratigraphic colunn.
`add_rank`(rank)	Adds another stratigraphic column rank to this stratigraphic column.
`is_equivalent`(other[, check_extra_metadata])	Returns True if this interpretation is essentially the same as the other; otherwise False.
`create_xml`([add_as_part, add_relationships, ...])	Creates xml tree for a stratigraphic column object.

Inherited from BaseResqpy

`__init__`(parent_model[, uuid, ...])	Initialises a Stratigraphic Column object.
`try_reuse`()	Look for an equivalent existing RESQML object and modify the uuid of this object if found.
`create_xml`([add_as_part, add_relationships, ...])	Creates xml tree for a stratigraphic column object.
`append_extra_metadata`(meta_dict)	Append a given dictionary of metadata to the existing metadata.
`__eq__`(other)	Implements equals operator; uses is_equivalent() otherwise compares class type and uuid.
`__ne__`(other)	Implements not equal operator.
`__repr__`()	String representation.

__init__(parent_model, uuid=None, rank_uuid_list=None, title=None, extra_metadata=None)[source]¶

Initialises a Stratigraphic Column object.

Parameters

parent_model (model.Model) – the model with which the new stratigraphic column will be associated
uuid (uuid.UUID, optional) – the uuid of an existing RESQML stratigraphic column from which this object will be initialised
rank_uuid_list (list of uuid, optional) – if not initialising for an existing stratigraphic column, the ranks can be established from this list of uuids for existing stratigraphic column ranks; ranks should be ordered from geologically oldest to youngest with increasing index values
title (str, optional) – the citation title of the new stratigraphic column; ignored if uuid is not None
extra_metadata (dict, optional) – extra metadata items for the new feature

add_rank(rank)[source]¶

Adds another stratigraphic column rank to this stratigraphic column.

Parameters: rank (StratigraphicColumnRank) – an established rank to be added to this stratigraphic column

Note

ranks should be ordered from geologically oldest to youngest, with increasing index values

append_extra_metadata(meta_dict)¶: Append a given dictionary of metadata to the existing metadata.

property citation_title¶: Citation block title equivalent to self.title.

create_xml(add_as_part=True, add_relationships=True, originator=None, reuse=True)[source]¶

Creates xml tree for a stratigraphic column object.

Parameters

add_as_part (bool, default True) – if True, the stratigraphic column is added to the parent model as a high level part
add_relationships (bool, default True) – if True and add_as_part is True, a relationship is created with each of the referenced stratigraphic column rank interpretations
originator (str, optional) – if present, is used as the originator field of the citation block
reuse (bool, default True) – if True, the parent model is inspected for any equivalent stratigraphic column and, if found, the uuid of this stratigraphic column is set to that of the equivalent part

Returns

lxml.etree._Element – the root node of the newly created xml tree for the stratigraphic column

is_equivalent(other, check_extra_metadata=True)[source]¶

Returns True if this interpretation is essentially the same as the other; otherwise False.

Parameters

other (StratigraphicColumn) – the other stratigraphic column to compare this one against
check_extra_metadata (bool, default True) – if True, then extra metadata items must match for the two columns to be deemed equivalent; if False, extra metadata is ignored in the comparison

Returns

bool – True if this stratigraphic column is essentially the same as the other; False otherwise

iter_ranks()[source]¶: Yields the stratigraphic column ranks which constitute this stratigraphic colunn.

property part¶: Standard part name corresponding to self.uuid.

property root¶: XML node corresponding to self.uuid.

try_reuse()¶

Look for an equivalent existing RESQML object and modify the uuid of this object if found.

Returns: boolean – True if an equivalent object was found, False if not

Note

by design this method may change this object’s uuid as a side effect

title¶: Citation title

originator¶: Creator of object. By default, user id.

uuid¶: Unique identifier
