class table.Table(array: <sphinx.ext.autodoc.importer._MockObject object at 0x7f8aa54c9250>, parser: <sphinx.ext.autodoc.importer._MockObject object at 0x7f8aa57db810>, aux_var_needed=True)[source]

The table object represents decision and constraint tables.

Attr name:str
Attr hit_policy:
Attr inputs:List[np.array]
Attr outputs:List[np.array]
Attr rules:List[np.array]
export(target_lang: str = 'idp')[source]

Export tries to find the hit policy for a table, and then returns the method needed to transfer the table to idp form. These hit policies are currently:

  • A, U, F -> translate to definitions;
  • E* -> translate to implications;
  • C+, C<, C>, C# -> translate to aggregates.

Every hit policy has it’s own method.

  • target_lang – the target output format. Either idp or idpz3.
  • check_error – a type of error to check a table for.
  • target_error – the name of the output for a table to check.
Returns method:

the output of export method for the table.

find_auxiliary() → List[str][source]

Every output in a C# table needs to use an auxiliary variable to work correctly. This method makes a list of those output variables, so that the auxiliary versions can be created.

Returns List[str]:

Method to decide the string format for a certain hit policy.

Returns str:the format string.

Method to generate the needed variables and quantifiers :returns variables, iquantors, oquantors: TODO

table.variname(string: str) → str[source]

Function to return the variable of a header in the form of “Type called var”

Parameters:string – the headerstring of which the variable name needs to be found.
Returns str:the variable name.
