Member Function Documentation

void ByteCode::build (  Instruction   insts )  [inline]

Given a list of Instructions, this method converts all offsets to pointers. Parameters: insts   list of instructions; labels must be accurate. See also: Instruction::offsetToPointer , ClassFile::parseMethod , ClassFile::relabel Definition at line 386 of file ByteCode.java. Referenced by ClassFile::parseMethod().

Instruction ByteCode::disassemble_bytecode (  byte   bc[], int   index )  [inline]

Main entry point for disassembling bytecode into Instructions; this method converts the given single bytecode into an Instruction (with label set to index). Parameters: bc   complete array of bytecode. index   offset within bc of the bytecode to parse. Returns: a single Instruction object; note that Instruction references will not be filled in (use build to post-process). See also: ClassFile::parseMethod , Instruction::parse , ByteCode::build Definition at line 433 of file ByteCode.java. Referenced by ClassFile::parseMethod().

Instruction ByteCode::locateInst (  int   index )  [inline]

Locates the Instruction in the list with the given label. Parameters: index   label of desired instruction Returns: Instruction object wiht that label, or null if not found. Definition at line 1129 of file ByteCode.java. Referenced by Instruction_Tableswitch::offsetToPointer(), Instruction_Lookupswitch::offsetToPointer(), Instruction_longbranch::offsetToPointer(), Instruction_intbranch::offsetToPointer(), and ClassFile::parseMethod().

Instruction ByteCode::locateInstr (  int   index, int   mini, int   maxi )  [inline, private]

Performs a binary search of the instructions[] array. Definition at line 1133 of file ByteCode.java. Referenced by locateInst().

void ByteCode::showCode (  Instruction   inst, int   startinst, cp_info   constant_pool[] )  [inline, static]

Displays the code (in the form of Instructions) for the given list of Instructions. Parameters: inst   input list of instructions. startinst   index of the label of the instruction at which to begin. constant_pool   constant pool of the ClassFile object. See also: ByteCode::showCode(Instruction, cp_info) Definition at line 1159 of file ByteCode.java.

void ByteCode::showCode (  Instruction   inst, cp_info   constant_pool[] )  [inline, static]

Displays the code (in the form of Instructions) for the given list of Instructions. Parameters: inst   input list of instructions. constant_pool   constant pool of the ClassFile object. See also: ByteCode::showCode(Instruction, int, cp_info) Definition at line 1149 of file ByteCode.java.
