## mars.assembler
Class Directives

    java.lang.Object
      mars.assembler.Directives

    public final class Directives

extends Object

Class representing MIPS assembler directives. If Java had enumerated types, these would probably be implemented that way. Each directive is represented by a unique object. The directive name is indicative of the directive it represents. For example, DATA represents the MIPS .data directive.

Method Detail

### matchDirective

    public static Directives matchDirective(String str)

  Find Directive object, if any, which matches the given String.

  Parameters:
    `str` - A String containing candidate directive name (e.g. ".ascii")
  Returns:
    If match is found, returns matching Directives object, else returns `null`.

### prefixMatchDirectives

    public static ArrayList prefixMatchDirectives(String str)

  Find Directive object, if any, which contains the given string as a prefix. For example, ".a" will match ".ascii", ".asciiz" and ".align"

  Parameters:
    `str` - A String
  Returns:
    If match is found, returns ArrayList of matching Directives objects, else returns `null`.

### toString

    public String toString()

  Produces String-ified version of Directive object

  Overrides:
    `toString` in class `Object`
  Returns:
    String representing Directive: its MIPS name

### getName

    public String getName()

  Get name of this Directives object

  Returns:
    name of this MIPS directive as a String

### getDescription

    public String getDescription()

  Get description of this Directives object

  Returns:
    description of this MIPS directive (for help purposes)

### getDirectiveList

    public static ArrayList getDirectiveList()

  Produces List of Directive objects

  Returns:
    MIPS Directive

### isIntegerDirective

    public static boolean isIntegerDirective(Directives direct)

  Lets you know whether given directive is for integer (WORD,HALF,BYTE).

  Parameters:
    `direct` - a MIPS directive
  Returns:
    true if given directive is FLOAT or DOUBLE, false otherwise

### isFloatingDirective

    public static boolean isFloatingDirective(Directives direct)

  Lets you know whether given directive is for floating number (FLOAT,DOUBLE).

  Parameters:
    `direct` - a MIPS directive
  Returns:
    true if given directive is FLOAT or DOUBLE, false otherwise.
