Method Detail

makeBlocks

public static TypedBlock[] makeBlocks(MethodInfo minfo,
                                      CodeAttribute ca,
                                      boolean optimize)
                               throws BadBytecode

Divides the method body into basic blocks. The type information of the first block is initialized.

Parameters:

optmize - if it is true and the method does not include branches, this method returns null.

Throws:

BadBytecode

toString2

protected void toString2(java.lang.StringBuffer sbuf)

Overrides:

toString2 in class BasicBlock

printTypes

private void printTypes(java.lang.StringBuffer sbuf,
                        int size,
                        TypeData[] types)

alreadySet

public boolean alreadySet()

setStackMap

public void setStackMap(int st,
                        TypeData[] stack,
                        int nl,
                        TypeData[] locals)
                 throws BadBytecode

Throws:

BadBytecode

resetNumLocals

public void resetNumLocals()

initFirstBlock

void initFirstBlock(int maxStack,
                    int maxLocals,
                    java.lang.String className,
                    java.lang.String methodDesc,
                    boolean isStatic,
                    boolean isConstructor)
             throws BadBytecode

Initializes the first block by the given method descriptor.

Parameters:

block - the first basic block that this method initializes.

className - a dot-separated fully qualified class name. For example, javassist.bytecode.stackmap.BasicBlock.

methodDesc - method descriptor.

isStatic - true if the method is a static method.

isConstructor - true if the method is a constructor.

Throws:

BadBytecode
