Overrides:

isUnresolvedNativeMethod in class MethodInfo

isMJI

public boolean isMJI()

Overrides:

isMJI in class MethodInfo

hasEmptyBody

public boolean hasEmptyBody()

Overrides:

hasEmptyBody in class MethodInfo

getNativePeer

public NativePeer getNativePeer()

getMethod

public Method getMethod()

getStackTraceSource

public String getStackTraceSource()

Overrides:

getStackTraceSource in class MethodInfo

getLineNumber

public int getLineNumber(Instruction pc)

Description copied from class: MethodInfo

Returns the line number for a given position.

Overrides:

executeNative

public Instruction executeNative(ThreadInfo ti)

isUnsatisfiedLinkError

protected boolean isUnsatisfiedLinkError(MJIEnv env)

getArguments

protected Object[] getArguments(ThreadInfo ti)

Get and convert the native method parameters off the ThreadInfo stack. Use the MethodInfo parameter type info for this (not the reflect.Method type array), or otherwise we won't have any type check
