Constants

public static final int MNEMONIC_RIGHT_PADDING_LENGTH_DEFAULT

Constant Value: 10 (0x0000000a)

Public Constructors

public GenericCodeFormatter ()

public GenericCodeFormatter (IVirtualMemory mem)

FOR TESTING ONLY

Public Methods

public final long createItemIdForAddress (long address)

public final long createItemIdForImmediate (long insnAddress, int opndIndexGlobal)

public final long createItemIdForMnemonic (InsnType insn)

public final long createItemIdForRegister (long regCode)

public final void formatAddress (long address, CodeDocumentPart out)

public void formatAddress (long address, IInstructionOperandGeneric opnd, CodeDocumentPart out)

Format an address regarding getDefaultAddressFormatter()

Parameters
address address to represent
opnd optional; IFF address is a relative address

public void formatDataDeclarator (int size, CodeDocumentPart out)

public final void formatImm (long address, IInstructionOperandSized opnd, long value, int opndIndexGlobal, CodeDocumentPart out)

public void formatInstruction (long address, InsnType insn, CodeDocumentPart out)

Displays only pure assembly code: Mnemonic and Operands, without address and bytecode.

public void formatOperand (long address, InsnType insn, IInstructionOperand opnd, int opndIndexGlobal, int opndDepth, CodeDocumentPart out)

Generic operand formatter. Can be overridden, although not recommended. If the processor uses custom instructions, that is, instructions that are neither IInstructionOperandGeneric or IInstructionOperandCMA, the processor should override this method.

public final void formatRelativeAddress (IInstructionOperandGeneric opnd, long address, CodeDocumentPart out)

public CharSequence generateExtraComment (long insnAddress, InsnType instruction)

Generate an optional string that will be displayed at the line instruction. The default implementation returns null.

Parameters
insnAddress address
instruction instruction. Can be null if no instruction is defined at this address.

public String generateExtraMethodComment (long address)

Generate an optional string that will be prepended to a function header comment. The default implementation returns null.

Parameters
address function address

public String generateExtraSectionHeader (ISegmentInformation segment)

public String generateExtraSegmentHeader (ISegmentInformation segment)

public String generateHeader ()
