Class ForeignExceptionAccess

java.lang.Object

com.oracle.truffle.api.nodes.Node

thc.runtime.ForeignExceptionAccess

All Implemented Interfaces:

com.oracle.truffle.api.nodes.NodeInterface, Cloneable

public final class ForeignExceptionAccess
extends com.oracle.truffle.api.nodes.Node

Cold exception translation. Normal foreign calls allocate no bridge object.

Method Summary

Modifier and Type	Method	Description
boolean	eligible(com.oracle.truffle.api.exception.AbstractTruffleException error)	Classification uses only Truffle's exception protocol.
RuntimeException	escaping(GuestException failure)	Only a compatible public exit asks the real Haskell dictionary whether a lazy SomeException contains our type.
RuntimeException	raise(com.oracle.truffle.api.exception.AbstractTruffleException error)	Called after carrier permission and pointer borrows have been restored, before an opaque Throwable could pass through Force's failure memoization.
RuntimeException	raise(com.oracle.truffle.api.exception.AbstractTruffleException error, ForeignExceptionBridge bridge)
RuntimeException	raiseHost(Exception error)
RuntimeException	raiseHost(Exception error, ForeignExceptionBridge bridge)
RuntimeException	raiseHost(RuntimeException error)	Native checked failures use the same host identity and genuine bridge as ordinary Java operations; no language-specific exception wrapper.

public ForeignExceptionAccess()

Method Details

eligible

public boolean eligible(com.oracle.truffle.api.exception.AbstractTruffleException error)

Classification uses only Truffle's exception protocol. It must not call user display/message/cause/stack accessors or recursively translate failure.

raise

public RuntimeException raise(com.oracle.truffle.api.exception.AbstractTruffleException error)

Called after carrier permission and pointer borrows have been restored, before an opaque Throwable could pass through Force's failure memoization.

raise

public RuntimeException raise(com.oracle.truffle.api.exception.AbstractTruffleException error,
 ForeignExceptionBridge bridge)

raiseHost

public RuntimeException raiseHost(RuntimeException error)

Native checked failures use the same host identity and genuine bridge as ordinary Java operations; no language-specific exception wrapper.

raiseHost

public RuntimeException raiseHost(Exception error)

raiseHost

public RuntimeException raiseHost(Exception error,
 ForeignExceptionBridge bridge)

escaping

public RuntimeException escaping(GuestException failure)

Only a compatible public exit asks the real Haskell dictionary whether a lazy SomeException contains our type. Projection failure remains guest failure.
