Method Detail

reconstructInstructions

public soot.coffi.Instruction reconstructInstructions()

Reconstructs the instruction stream by appending the Instruction lists associated with each basic block.

Note that this joins up the basic block Instruction lists, and so they will no longer end with null after this.

Returns:

the head of the list of instructions.

jimplify

public boolean jimplify(soot.coffi.cp_info[] constant_pool,
                        int this_class,
                        soot.coffi.BootstrapMethods_attribute bootstrap_methods_attribute,
                        JimpleBody listBody)

Main.v() entry point for converting list of Instructions to Jimple statements; performs flow analysis, constructs Jimple statements, and fixes jumps.

Parameters:

constant_pool - constant pool of ClassFile.

this_class - constant pool index of the CONSTANT_Class_info object for this' class.

bootstrap_methods_attribute -

Returns:

true if all ok, false if there was an error.
