Describes regular expressions.

Field Summary

Fields

Modifier and Type	Field and Description
boolean	m_private_rexp This flag is set if the regular expression has a label prefixed with the # symbol - this indicates that the purpose of the regular expression is solely for defining other regular expressions.
TokenProduction	m_tpContext If this is a top-level regular expression (nested directly within a TokenProduction), then this field point to that TokenProduction object.
