# Error : Error management

JSRE currently enhances JavaScript standard Error objects.

# new Error(message)

• message {String} Error message.
• Returns: {Error} A error object.

Create an Error object. Error objects supported by JSRE include: Error, EvalError, RangeError, ReferenceError, SyntaxError, TypeError, URIError.

# Example

throw new Error('Test error!');
throw new TypeError('Test type error!');

# Error.stackTraceLimit

• {Integer}

The call stack depth saved when the Error object was created. The default value is 32. This property is write-only. 0 means unlimited depth.

# new ExtError(message, code[, errno[, info]])

• message {String} Error message.
• code {String} Error code.
• errno {Integer} Can save operating system kernel error numbers.
• info {Object} Error extension information.
• Returns: {Error} A error object.

Create an extended error object. error.name is 'Error'.

# Example

try {
  throw new ExtError('MSG', 'ERR_TEST', sys.errno());
} catch (error) {
  console.log(error.message, error.code, error.errno);
}

# error.stack

• {Array}

Call stack record when creating Error object.

# Example

var error = new TypeError('aaaa');
console.log(error.stack);

# error.name

• {String}

Get error type. It may contain the following:

• 'Error' Common type error.
• 'EvalError' eval() function error.
• 'RangeError' Value is outside the specified range.
• 'ReferenceError' Illegal reference.
• 'SyntaxError' Syntax error.
• 'TypeError' Type error.
• 'URIError' Error from encodeURI() function.

# error.message

• {String}

Error message saved when creating the error object.

# error.code

• {String}

Error code saved when creating the extended error object.

# error.errno

• {Integer}

Operating system error number saved when creating the extended error object. This is an optional property of the ExtError object.

# error.info

• {Object}

Additional information saved when creating the extended error object. This is an optional property of the ExtError object.
