create

public static InvalidArrayIndexException create(long invalidIndex)

Creates an InvalidArrayIndexException to indicate that an array index is invalid.

This method is designed to be used in compiled code paths.

Parameters:

invalidIndex - the index that could not be accessed

Since:

19.0

create

public static InvalidArrayIndexException create(long invalidIndex,
 Throwable cause)

Creates an InvalidArrayIndexException to indicate that an array index is invalid.

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.

Parameters:

invalidIndex - the index that could not be accessed

cause - the guest language exception that caused the error.
