Public Methods

public abstract String format (IInstruction insn, long address)

Format the operand, assuming it is used by an instruction at the provided address.

Parameters

insn	optional instruction using this operand. Note that this operand may not be directly returned by `insn.getOperands()`, e.g., in the case of instructions with nested operands
address	optional instruction address, 0 if none. The instruction address is sometimes necessary to properly render PC-dependent operands

Returns

simple string representation of the operand
