public static final Invoke make

Constructor Details

Invoke

public Invoke(String name,
              char kind)

Invoke

public Invoke(String name,
              char kind,
              Language language)

Method Details

apply

public void apply(CallContext ctx)
            throws Throwable
Overrides:
apply in interface Procedure

applyN

public Object applyN(Object[] args)
            throws Throwable
Overrides:
applyN in interface ProcedureN

checkKnownClass

public static int checkKnownClass(Type type,
                                  Compilation comp)
Check if class exists.
Returns:
1 if class actually exists; -1 is class should exist, but doesn't; and 0 otherwise.

getMethods

protected PrimProcedure[] getMethods(ObjectType ctype,
                                     String mname,
                                     ClassType caller)

getStaticMethod

public static PrimProcedure getStaticMethod(ClassType type,
                                            String name,
                                            Expression[] args)

inline

public Expression inline(ApplyExp exp,
                         ExpWalker walker)
Specified by:
inline in interface CanInline

inlineClassName

public static ApplyExp inlineClassName(ApplyExp exp,
                                       int carg,
                                       InlineCalls walker)
Resolve class specifier to ClassType at inline time. This is an optimization to avoid having a module-level binding created for the class name.

invoke$V

public static Object invoke$V(Object[] args)
            throws Throwable

invokeStatic$V

public static Object invokeStatic$V(Object[] args)
            throws Throwable

lookupMethods

protected MethodProc lookupMethods(ObjectType dtype,
                                   Object name)

make$V

public static Object make$V(Object[] args)
            throws Throwable

makeInvokeStatic

public static ApplyExp makeInvokeStatic(ClassType type,
                                        String name,
                                        Expression[] args)
Return an ApplyExp that will call a method with given arguments.
Parameters:
type - the class containing the method we want to call.
name - the name of the method we want to call
args - the arguments to the call
Returns:
an ApplyExp representing the call

numArgs

public int numArgs()
Overrides:
numArgs in interface Procedure
