Enclosing class:

Register

public static class Register.Set

extends java.lang.Object

The Set class represents a set of registers. This is used to represent classes of registers that are used as operands to various instructions. For example, an instruction might expect one of its operands to be a general purpose register that has a number greater than 15; a set of those registers can be constructed and then a membership test performed.

In practice, the needed register sets are all allocated statically.

Field Summary

java.lang.String

contents The contents field stores a string that represents a summary of the registers that are in this set.

Method Summary

boolean	contains(Register reg) The contains() method tests for membership.
java.lang.String	toString() The toString() method converts this set to a string representation.

Field Detail

contents

public final java.lang.String contents

The contents field stores a string that represents a summary of the registers that are in this set. An example string for the even registers would be "{r0, r2, ..., r30}".

Method Detail

contains

public boolean contains(Register reg)

The contains() method tests for membership. Given a register, it will return true if that register is a member of this set, and false otherwise.

Parameters:

reg - the register to test membership of

Returns:

true if the specified register is a member of this set; false otherwise

toString

public java.lang.String toString()

The toString() method converts this set to a string representation. In this implementation, it simply returns the string representation of the contents.

Returns:

a string representation of this register set
