Enum Constant Detail

Api

public static final LSErrorCode Api

Code used for errors related to API functions. Used when you call a function in a wrong way or with inappropriate parameters. Examples of error messages:

• Argument 'argName' cannot be null.
• Argument 'argName' does not belong to this instance of LocalSolver.
• Argument 'argName' must be positive.
• Argument 'argName' cannot be an empty String.
• This method is only allowed in state Modeling (the model must not be closed).

File

public static final LSErrorCode File

Code used when an error related to input/output operations occurs. Examples of error messages:

• File doesn't exist.
• File is corrupted.
• Cannot open file.
• File format is not recognized.

Model

public static final LSErrorCode Model

Code used when a problem related to the structure of the model occurs. Examples of error messages:

• At least one objective is required in the model.
• A cycle of length 'n' was detected in the model.
• Number of operands ('n') is too small: at least 'm' operands are expected for 'operator'.
• Operand 'n' of 'operator' must be 'type'. Type provided: 'otherType'.

Callback

public static final LSErrorCode Callback

Code used when an error is encountered in a user callback.

License

public static final LSErrorCode License

Code used when a problem related to licensing occurs. That could be a problem with the license itself (expiration, hardware signature, etc.), or a problem related to input/output or networking operations. Examples of error messages:

• Incorrect license number.
• This license key is not compatible with the current hardware. Please contact your reseller.
• Property prop is missing in file [file]
• Fail to contact the token server. Check your connection.
• This license is not compatible with the current hardware.
• No token available. All tokens are currently in use.

Solver

public static final LSErrorCode Solver

Code used when a problem occurs during the resolution.

Internal

public static final LSErrorCode Internal

Internal LocalSolver error.

Modeler

public static final LSErrorCode Modeler

Code used when an error is encountered in the modeler.

Cloud

public static final LSErrorCode Cloud

Code used when an error is encountered while using the cloud service.

Method Detail

values

public static LSErrorCode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LSErrorCode c : LSErrorCode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LSErrorCode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
