When reading the items, the DataStore will return a generator. The items will be ordered lexicographically according to their name.

There is a serialization protocol to store objects in the datastore. An object is serializable if it has a method __toh5__ returning an array and a dictionary, and a method __fromh5__ taking an array and a dictionary and populating the object. For an example of use see openquake.hazardlib.site.SiteCollection.

openquake.commonlib.datastore.persistent_attribute(key)

Persistent attributes are persisted to the datastore and cached. Modifications to mutable objects are not automagically persisted. If you have a huge object that does not fit in memory use the datastore directory (for instance, open a HDF5 file to create an empty array, then populate it). Notice that you can use any dict-like data structure in place of the datastore, provided you can set attributes on it. Here is an example:

>>> class Datastore(dict):
...     "A fake datastore"

>>> class Store(object):
...     a = persistent_attribute('a')
...     def __init__(self, a):
...         self.datastore = Datastore()
...         self.a = a  # this assegnation will store the attribute

>>> store = Store([1])
>>> store.a  # this retrieves the attribute
[1]

>>> store.a = store.a  # remember to store the modified attribute!

Parameters:key – the name of the attribute to be made persistent Returns:a property to be added to a class with a .datastore attribute

Bases: object

Parameters:

• filename – Full pathname of logic tree file
• validate – Boolean indicating whether or not the tree should be validated while parsed. This should be set to True on initial load of the logic tree (before importing it to the database) and to False on workers side (when loaded from the database).

apply_branchset(branchset_node, branchset)

See superclass’ method for description and signature specification.

Parses branchset node’s attribute @applyToBranches to apply following branchests to preceding branches selectively. Branching level can have more than one branchset exactly for this: different branchsets can apply to different open ends.

Checks that branchset tries to be applied only to branches on previous branching level which do not have a child branchset yet.

collect_source_model_data(source_model)

Parse source model file and collect information about source ids, source types and tectonic region types available in it. That information is used then for validate_filters() and validate_uncertainty_value().

gen_source_models(gsim_lt)

Yield empty SourceModel instances (one per effective realization)

make_apply_uncertainties(branch_ids)

Parse the path through the source model logic tree and return “apply uncertainties” function.

Parameters:branch_ids – List of string identifiers of branches, representing the path through source model logic tree. Returns:Function to be applied to all the sources as they get read from the database and converted to hazardlib representation. Function takes one argument, that is the hazardlib source object, and applies uncertainties to it in-place.

parse_branches(branchset_node, branchset, validate)

Create and attach branches at branchset_node to branchset.

Parameters:

• branchset_node – Same as for parse_branchset().
• branchset – An instance of BranchSet.
• validate – Whether or not branches’ uncertainty values should be validated.

Checks that each branch has valid value, unique id and that all branches have total weight of 1.0.

Returns:None, all branches are attached to provided branchset.

parse_branchinglevel(branchinglevel_node, depth, validate)

Parse one branching level.

Parameters:

• branchinglevel_node – etree.Element object with tag “logicTreeBranchingLevel”.
• depth – The sequential number of this branching level, based on 0.
• validate – Whether or not the branching level, its branchsets and their branches should be validated.

Enumerates children branchsets and call parse_branchset(), validate_branchset(), parse_branches() and finally apply_branchset() for each.

Keeps track of “open ends” – the set of branches that don’t have any child branchset on this step of execution. After processing of every branching level only those branches that are listed in it can have child branchsets (if there is one on the next level).

parse_branchset(branchset_node, depth, number, validate)

Create BranchSet object using data in branchset_node.

Parameters:

• branchset_node – etree.Element object with tag “logicTreeBranchSet”.
• depth – The sequential number of branchset’s branching level, based on 0.
• number – Index number of this branchset inside branching level, based on 0.
• validate – Whether or not filters defined in branchset and the branchset itself should be validated.

Returns:

An instance of BranchSet with filters applied but with no branches (they’re attached in parse_branches()).

parse_filters(branchset_node, uncertainty_type, filters)

See superclass’ method for description and signature specification.

Converts “applyToSources” filter value by just splitting it to a list.

parse_tree(tree_node, validate)

Parse the whole tree and point root_branchset attribute to the tree’s root.

parse_uncertainty_value(node, branchset)

See superclass’ method for description and signature specification.

Doesn’t change source model file name, converts other values to either pair of floats or a single float depending on uncertainty type.

Return the model name and a list of branch ids.

Parameters:random_seed (int) – the seed used for the sampling

samples_by_lt_path()

Returns a dictionary lt_path -> how many times that path was sampled

validate_branchset(branchset_node, depth, number, branchset)

See superclass’ method for description and signature specification.

Checks that the following conditions are met:

• All other branchsets must not be of type “sourceModel” or “gmpeModel”.

validate_filters(branchset_node, uncertainty_type, filters)

See superclass’ method for description and signature specification.

Checks that the following conditions are met:

• “sourceModel” uncertainties can not have filters.
• Absolute uncertainties must have only one filter – “applyToSources”, with only one source id.
• All other uncertainty types can have either no or one filter.
• Filter “applyToSources” must mention only source ids that exist in source models.
• Filter “applyToTectonicRegionType” must mention only tectonic region types that exist in source models.
• Filter “applyToSourceType” must mention only source types that exist in source models.

validate_uncertainty_value(node, branchset)

See superclass’ method for description and signature specification.

Checks that the following conditions are met:

• For uncertainty of type “sourceModel”: referenced file must exist and be readable. This is checked in collect_source_model_data() along with saving the source model information.
• For uncertainty of type “abGRAbsolute”: value should be two float values.
• For both absolute uncertainties: the source (only one) must be referenced in branchset’s filter “applyToSources”.
• For all other cases: value should be a single float value.
