Public methods

rethrowAsIOException

Added in API level 30
fun rethrowAsIOException(): IOException

Throws an IOException with a message based on getMessage() and with this instance as the cause.

This method always terminates by throwing the exception. Callers can write throw e.rethrowAsIOException() to make that clear to the compiler.

Return
IOException This value cannot be null.

rethrowAsSocketException

Added in API level 30
fun rethrowAsSocketException(): SocketException

Throws a SocketException with a message based on getMessage() and with this instance as the cause.

This method always terminates by throwing the exception. Callers can write throw e.rethrowAsIOException() to make that clear to the compiler.

Return
SocketException This value cannot be null.

Properties

errno

Added in API level 21
val errno: Int

The errno value, for comparison with the E constants in OsConstants.

message

Added in API level 21
val message: String?

Converts the stashed function name and errno value to a human-readable string. We do this here rather than in the constructor so that callers only pay for this if they need it.

Return
String? the detail message string of this Throwable instance (which may be null).
