HuginError

An API function was called with an invalid argument.

A fatal error occurred during an input or output operation. This could be a failure to open a specified file, a failure to create a file due to wrong permissions, a failure during a write operation due to the disk running full, etc.

Hugin ran out of memory while carrying out some operation.

LIMIDs with CG nodes are not supported.

An attempt has been made to assign a name that is already in use to a node or a class.

Names used for classes, nodes, and attributes must have the same form as a C identifier.

An attempt was made to create a cycle in the network.

The link could not be created as it would cause a cyclic dependency in the evaluation of function nodes.

A functional dependency was detected. Some Hugin API operations (including the SPU algorithm for LIMIDs) do not support such networks.

The true size is too large to represent within the `size_t’ type.

Logical relations in the distribution has caused a fast-retraction propagation to fail.

Possibly significant floating-point rounding error detected.

The supplied password does not match the password stored in the Hugin KB file.

This Hugin KB file is not supported. That is, the file was produced by a version of the Hugin API that is either very old or newer than the version of this module.

This Hugin KB file is of the wrong type for this operation. A Hugin KB file contains either a domain or a class collection.

This file is not a valid Hugin KB file. Either the file is not a Hugin KB file, or the file has been damaged.

The operation requires a compiled domain.

An invalid value or an invalid distribution was found in a probability potential or policy: Values must be nonnegative and finite, and the sum of values in a distribution must be positive and finite.

Chain graph: Zero probability found in parent potential.

The specified elimination sequence is invalid. Possible causes: It contains a utility or a real-valued function node, a node appears twice, the nodes are `out-of-order’, or the sequence is incomplete.

The junction tree potentials are invalid.

The density of the evidence presented is too low to represent as a positive floating-point number.

Zero variance detected during a conditioning operation.

Propagation of inconsistent evidence has been attempted, or underflow has occurred.

Overflow occurred during propagation.

This operation is not supported when the junction tree potentials have CG evidence incorporated.

Normalization with a zero (or underflowed) normalization constant has been attempted.

The operation is not supported on compressed domains.

The compressed version of some non-clique table is too large.

The specified evidence violates the “free will” condition, or evidence on a decision node is not an instantiation.

A case state index larger than 32767 has been specified.

An error occurred during parsing.

The supplied expression is invalid (e.g., wrong type).

A syntax error has been detected while parsing an expression.

Division by zero has been attempted.

Invalid arguments have been passed to a standard mathematical or probability/density function.

A probability/density function or a function value could not be computed.

The state range of the node is insufficient for the chosen standard distribution.

The state values of a numeric node do not form an increasing sequence, or infinite values are used incorrectly.

Cyclic hierarchies of class instances are not allowed.

An actual input node is incompatible with the formal input node, or there are multiple occurrences of the same parent.

The Hugin API could not establish the C locale!

The license data is invalid (or could not be found).

The time limited license has expired.

The limits of this software have been exceeded (too many states or too many cases).

Undocumented

A method has been called on a “dead” object (i.e., the corresponding native object has been deleted).
