Method Detail

invoke$V

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

Throws:

java.lang.Throwable

invokeStatic$V

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

Throws:

java.lang.Throwable

make$V

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

Throws:

java.lang.Throwable

apply

public void apply(CallContext ctx)
           throws java.lang.Throwable

Description copied from class: Procedure

Call this Procedure using the explicit-CallContext-convention. The input arguments are (by default) in stack.args; the result is written to ctx.consumer.

Overrides:

apply in class Procedure

Throws:

java.lang.Throwable

applyN

public java.lang.Object applyN(java.lang.Object[] args)
                        throws java.lang.Throwable

Specified by:

applyN in class ProcedureN

Throws:

java.lang.Throwable

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12).

Overrides:

numArgs in class Procedure

lookupMethods

protected MethodProc lookupMethods(ObjectType dtype,
                                   java.lang.Object name)

getMethods

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

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.

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.

inline

public Expression inline(ApplyExp exp,
                         ExpWalker walker)

Description copied from interface: CanInline

Inline an application of this Procedure and return result. Can return original expression.

Specified by:

inline in interface CanInline

makeInvokeStatic

public static ApplyExp makeInvokeStatic(ClassType type,
                                        java.lang.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

getStaticMethod

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