Field Detail

OPCODES

public static final String[] OPCODES

The names of the Java Virtual Machine opcodes.

TYPES

public static final String[] TYPES

Types for operand parameter of the MethodVisitor.visitIntInsn(int, int) method when opcode is NEWARRAY.

text

public final List text

The text to be printed. Since the code of methods is not necessarily visited in sequential order, one method after the other, but can be interlaced (some instructions from method one, then some instructions from method two, then some instructions from method one again...), it is not possible to print the visited instructions directly to a sequential stream. A class is therefore printed in a two steps process: a string tree is constructed during the visit, and printed to a sequential stream at the end of the visit. This string tree is stored in this field, as a string list that can contain other string lists, which can themselves contain other string lists, and so on.

buf

protected final StringBuffer buf

A buffer that can be used to create strings.

Constructor Detail

AbstractVisitor

protected AbstractVisitor()

Constructs a new AbstractVisitor.

Method Detail

getText

public List getText()

Returns the text constructed by this visitor.

Returns:

the text constructed by this visitor.

print

public void print(PrintWriter pw)

Prints the text constructed by this visitor.

Parameters:

pw - the print writer to be used.

appendString

public static void appendString(StringBuffer buf,
                                String s)

Appends a quoted string to a given buffer.

Parameters:

buf - the buffer where the string must be added.

s - the string to be added.

getDefaultAttributes

public static Attribute[] getDefaultAttributes()

Returns the default ASMifiable prototypes.

Returns:

the default ASMifiable prototypes.
