Error

The base class of all unrecoverable runtime errors.

This represents the category of Throwable objects that are not safe to catch and handle. In principle, one should not catch Error objects, as they represent unrecoverable runtime errors. Certain runtime guarantees may fail to hold when these errors are thrown, making it unsafe to continue execution after catching them.

class Error : Throwable {

this(string msg, Throwable nextInChain);

this(string msg, string file, size_t line, Throwable nextInChain);

Throwable bypassedException;

}

Constructors

this this(string msg, Throwable nextInChain): Creates a new instance of Error. The nextInChain parameter is used internally and should always be null when passed by user code. This constructor does not automatically throw the newly-created Error; the throw statement should be used for that purpose.
this this(string msg, string file, size_t line, Throwable nextInChain): Undocumented in source.

Members

Variables

bypassedException Throwable bypassedException;: The first Exception which was bypassed when this Error was thrown, or null if no Exceptions were pending.

Inherited Members

From Throwable

TraceInfo interface TraceInfo: Undocumented in source.
msg string msg;: A message describing the error.
file string file;: The file name of the D source code corresponding with where the error was thrown from.
line size_t line;: The line number of the D source code corresponding with where the error was thrown from.
info TraceInfo info;: The stack trace of where the error happened. This is an opaque object that can either be converted to string, or iterated over with foreach to extract the items in the stack trace (as strings).
next inout(Throwable) next [@property getter]
next Throwable next [@property setter]: Replace next in chain with tail. Use chainTogether instead if at all possible.
refcount uint refcount()
opApply int opApply(int delegate(Throwable) dg): Loop over the chain of Throwables.
chainTogether Throwable chainTogether(Throwable e1, Throwable e2): Append e2 to chain of exceptions that starts with e1.
~this ~this(): Undocumented in source.
message const(char)[] message(): Get the message describing the error. Base behavior is to return the Throwable.msg field. Override to return some other error message.
