Class Mnemonic

public class Mnemonic
extends java.lang.Object

This class encapsulates an opcode mnemonic that may have multiple forms. A mnemonic is a human readable form of an opcode. For instance, "09EEwmwl" might be represented with "LDX #w". There may be multiple forms of a single mnemonic. For instance, in the 6809 the "BCC" (branch if carry clear) and "BHS" (branch if higher or the same) are exactly the same. The programmer can pick either form. Thus the mnemonic representation here includes collections for multiple forms. Mnemonics are lists of two types of tokens: Absolute text matches like "LDX #" in the above example Place holders for numbers like "w" in the above example This class assumes that a text representation of the mnemonic assumes that numeric-fill-ins are represented with single-lower-case-letters. The mnemonics are parsed into tokens here. For instance, a line like "A=A+PORT[b+i]" would result in the following tokens: "A=A+PORT[b" ... b ... "+" ... i ... "]" MATCH NUMBER MATCH NUMBER MATCH
