Numerous data members

[sm43]

If a class has a lot of data members, is there a way a quick way to write the accessors, mutators and parametrized constructor (constructor that initializes data members based on values passed to it) that will take far less amount of code, and is not too elaborate..


Thanks..

You'll probably always need the getters and setters (accessor/mutators)....an IDE like Forte will generate them for you to save some typing. Jeremy Nicholson, Director of

You can even do it with a little perl

#!/usr/bin/perl -w

my @vars;

while(<DATA>) {
  if( /(\S+)\s+(\S+)\s*;/ ) {
    push @vars, { type => $1, name => $2 };
  }
  print;
}

print << &quot;EOF&quot;;
  public CONSTRUCTOR(
${\(&args())}
  )
  {
${\(&init())}
  }

${\(&sets())}
${\(&gets())}
EOF

sub args {
  return join(&quot;,\n&quot;, map { &quot;    $_->{type} $_->{name}&quot; } @vars );
}

sub init {
  return join(&quot;\n&quot;, map { &quot;    this.$_->{name} = $_->{name};&quot; } @vars );
}
sub sets {
  return join(&quot;\n&quot;, map {
    &quot;  public void set&quot;.ucfirst($_->{name}).&quot;($_->{type} $_->{name}) { this.$_->{name} = $_->{name}; }&quot; } @vars );
}
sub gets {
  return join(&quot;\n&quot;, map {
    &quot;  public $_->{type} get&quot;.ucfirst($_->{name}).&quot;() { return $_->{name}; }&quot; } @vars );
}

__END__

public int x;
public Integer y;
