Error

open class Error : Throwable
kotlin.Any
   ↳ kotlin.Throwable
   ↳ java.lang.Error

An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. The ThreadDeath error, though a "normal" condition, is also a subclass of Error because most applications should not try to catch it.

A method is not required to declare in its throws clause any subclasses of Error that might be thrown during the execution of the method but not caught, since these errors are abnormal conditions that should never occur. That is, Error and its subclasses are regarded as unchecked exceptions for the purposes of compile-time checking of exceptions.

Summary

Public constructors

Constructs a new error with null as its detail message.

Error(message: String!)

Constructs a new error with the specified detail message.

Error(message: String!, cause: Throwable!)

Constructs a new error with the specified detail message and cause.

Error(cause: Throwable!)

Constructs a new error with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause).

Protected constructors
Error(message: String!, cause: Throwable!, enableSuppression: Boolean, writableStackTrace: Boolean)

Constructs a new error with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.

Error

Error()

Constructs a new error with null as its detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

Error

Added in API level 1
Error(message: String!)

Constructs a new error with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

Parameters
message String!: the detail message. The detail message is saved for later retrieval by the getMessage() method.

Error

Added in API level 1
Error(
    message: String!,
    cause: Throwable!)

Constructs a new error with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated in this error's detail message.

Parameters
message String!: the detail message (which is saved for later retrieval by the getMessage() method).
cause Throwable!: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Error

Added in API level 1
Error(cause: Throwable!)

Constructs a new error with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for errors that are little more than wrappers for other throwables.

Parameters
cause Throwable!: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Protected constructors

Error

Added in API level 1
protected Error(
    message: String!,
    cause: Throwable!,
    enableSuppression: Boolean,
    writableStackTrace: Boolean)

Constructs a new error with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.

Parameters
message String!: the detail message.
cause Throwable!: the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
enableSuppression Boolean: whether or not suppression is enabled or disabled
writableStackTrace Boolean: whether or not the stack trace should be writable
