abstract def boundedLength: Option[Int]

If the expression has a computable maximum length, this returns it.
If the expression has a computable maximum length, this returns it. Otherwise, it returns None.
This is used for determining whether an expression is suitable for look-behind.

abstract def expression: String

Returns the regular expression represented by this object, in a form suitable to passing to the java.util.regex.Pattern class.

abstract def possiblyZeroLength: Boolean

Indicates whether the expression may possibly be zero length.

Expression
abstract def repetitionInvalidatesBounds: Boolean

Indicates whether applying repetition to the expression invalidates the boundedness computation.
Indicates whether applying repetition to the expression invalidates the boundedness computation. This generally indicates that the expression may match a zero-repetition ({0, n} or ?).
This is used to determine boundedness of enclosing expressions.
