public static UnknownKeyException create(Object unknownKey)
UnknownKeyException
to indicate that a key is missing in the hash object.
This method is designed to be used in compiled
code paths.

UnknownKeyException
to indicate that a key is missing in the hash object.
In addition a cause may be provided. The cause should only be set if the guest language code
caused this problem. An example for this is a language specific proxy mechanism that invokes
guest language code to describe an object. If the guest language code fails to execute and
this interop exception is a valid interpretation of the error, then the error should be
provided as cause. The cause can then be used by the source language as new exception cause
if the InteropException
is translated to a source language error. If the
InteropException
is discarded, then the cause will most likely get discarded by the
source language as well. Note that the cause must be of type
AbstractTruffleException
otherwise an
IllegalArgumentException
is thrown.
This method is designed to be used in compiled
code paths.
