Field Summary

Fields
Modifier and Type	Field	Description
`java.lang.String`	`label`	The label of the regular expression (if any).
`java.util.List<Token>`	`lhsTokens`	The LHS to which the token value of the regular expression is assigned.
`boolean`	`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.
`Token`	`rhsToken`	We now allow qualified access to token members.
`TokenProduction`	`tpContext`	If this is a top-level regular expression (nested directly within a TokenProduction), then this field point to that TokenProduction object.

- Field Detail
  - label
```
public java.lang.String label
```
    The label of the regular expression (if any). If no label is present, this is set to "".
  - lhsTokens
```
public java.util.List<Token> lhsTokens
```
    The LHS to which the token value of the regular expression is assigned. In case there is no LHS, then the list remains empty.
  - rhsToken
```
public Token rhsToken
```
    We now allow qualified access to token members. Store it here.
  - private_rexp
```
public boolean 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.
  - tpContext
```
public TokenProduction tpContext
```
    If this is a top-level regular expression (nested directly within a TokenProduction), then this field point to that TokenProduction object.
