Method Details

buildString

public static void buildString(org.objectweb.asm.MethodVisitor methodVisitor,
 int itemCount)

Constructs a string from the top itemCount on the stack. Basically generate the following code:

     StringBuilder builder = new StringBuilder();
     builder.insert(0, TOS);
     builder.insert(0, TOS1);
     ...
     builder.insert(0, TOS(itemCount - 1));
     TOS' = PythonString.valueOf(builder.toString())
 

Parameters:

itemCount - The number of items to put into collection from the stack

formatValue

public static void formatValue(org.objectweb.asm.MethodVisitor methodVisitor,
 PythonBytecodeInstruction instruction)

TOS1 is a value and TOS is an optional format string (either PythonNone or PythonString). Depending on instruction.arg, does one of several things to TOS1 before formatting it (as specified by StringOpDescriptor.FORMAT_VALUE: arg & 3 == 0: Do nothing arg & 3 == 1: Call str() on value before formatting it arg & 3 == 2: Call repr() on value before formatting it arg & 3 == 3: Call ascii() on value before formatting it if arg & 4 == 0, TOS is the value to format, so push PythonNone before calling format if arg & 4 == 4, TOS is a format string, use it in the call

print

public static void print(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

TOS is an PythonLikeObject to be printed. Pop TOS off the stack and print it.
