Method Detail

opcode

public final int opcode()

getReturnType

public Type getReturnType()

setReturnType

public void setReturnType(Type retType)

getReturnType

public Type getReturnType(Expression[] args)

Specified by:

getReturnType in interface Inlineable

takesVarArgs

public boolean takesVarArgs()

Return true iff the last parameter is a "rest" argument.

getVarBuffer

public java.lang.Object getVarBuffer()

Return a buffer that can contain decoded (matched) arguments.

Overrides:

getVarBuffer in class MethodProc

numArgs

public int numArgs()

Description copied from class: Procedure

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

Overrides:

numArgs in class Procedure

match

public java.lang.RuntimeException match(java.lang.Object vars,
                                        java.lang.Object[] args)

Description copied from class: MethodProc

Match the incoming arguments.

Overrides:

match in class MethodProc

Tags copied from class: MethodProc

Parameters:

args - the incoming argument list

vars - where to save the matched result on success

Returns:

null if the match succeeded, else an exception

applyV

public java.lang.Object applyV(java.lang.Object vars)

Overrides:

applyV in class MethodProc

getStaticFlag

public final boolean getStaticFlag()

getParameterTypes

public final Type[] getParameterTypes()

compileArgs

public static void compileArgs(Expression[] args,
                               Type thisType,
                               Type[] argTypes,
                               boolean variable,

                               Compilation comp)

Compile arguments and push unto stack.

Parameters:

args - arguments to evaluate and push.

thisType - If we care calling a non-static function, then args[0] is the receiver and thisType is its expected class. If thisType==Type.void_type, ignore argType[0]. If this_type==null, no special handling of args[0] or argTypes[0].
