Method Details

addLoadInstruction

public static void addLoadInstruction(org.jboss.classfilewriter.code.CodeAttribute code,
 String type,
 int variable)

Adds the correct load instruction based on the type descriptor

Parameters:

code - the bytecode to add the instruction to

type - the type of the variable

variable - the variable number

pushClassType

public static void pushClassType(org.jboss.classfilewriter.code.CodeAttribute b,
 String classType)

Pushes a class type onto the stack from the string representation This can also handle primitives

Parameters:

b - the bytecode

classType - the type descriptor for the class or primitive to push. This will accept both the java.lang.Object form and the Ljava/lang/Object; form

getName

public static String getName(String descriptor)
