YANG String Encoding

• Strings can be specified in several ways:

• • Double Quoted String: whitespace allowed, but it is adjusted (escape character sequences replaces, whitespace trimmed)
  • Single Quoted String: whitespace allowed, and is preserved (this form is safest for pattern strings)
  • Unquoted String: no whitespace allowed (Language tokens like ‘{‘ and ‘}’ are not allowed.)

• Strings can be specified in fragments if desired:

• • “foobarbaz” is the same as “foo” + “bar” + “baz”
  • Mixing forms is allowed: “foo” + bar + ‘baz’

• For comparison purposes, the quotes are ignored

• • “foo” is equivalent to foo or ‘foo’
  • “foo bar “ is not the same as ‘foo bar ‘ (extra space)
