class PDSketchCSPParser[source]#

Bases: PDSketchParser

Parser for PDSketch domain and problem files. Users should not use this class directly. Instead, use the following functions:

Methods

incremental_define_domain(domain, tree)

Incrementally define a PDSketch domain from a tree.

load(file)

Load a domain or problem file and return the corresponding tree.

loads(string)

Load a domain or problem string and return the corresponding tree.

make_csp_problem(tree, domain[, ...])

Construct a PDSketch problem from a tree.

make_domain(tree[, domain_file_paths])

Construct a PDSketch domain from a tree.

make_expression(domain, tree[, variables])

Construct a PDSketch expression from a tree.

make_problem(tree, domain[, ...])

Construct a PDSketch problem from a tree.

Attributes
