Method Detail

getDescriptor

HotSpotForeignCallDescriptor getDescriptor()

Specified by:

getDescriptor in interface ForeignCallLinkage

setCompiledStub

void setCompiledStub(Stub stub)

getEffect

HotSpotForeignCallLinkage.RegisterEffect getEffect()

isCompiledStub

boolean isCompiledStub()

Determines if this is a call to a compiled stub.

getStub

Stub getStub()

Gets the stub, if any, this foreign call links to.

finalizeAddress

void finalizeAddress(Backend backend)

getAddress

long getAddress()

Determines if a JavaFrameAnchor needs to be set up and torn down around this call.

getSymbol

String getSymbol()

Gets the VM symbol associated with the target address of the call.
