getIToken

@Deprecated
protected IToken getIToken(int i)

Deprecated.

Before 3.0, this method was used with the now-deprecated "dollar"getToken macro (which provided token index in the prsStream) to obtain an IToken f a rule given the index of the right hand side token in the said rule. In 3.0 a convenience method has been introduced in order to directly return the IToken, given the index of the right hand side token in the rule.

In an action-block of a rule, instead of doing getIToken("dollar"getToken(i)) you should do getRhsTokenText(i)

Parameters:

i - the right hand side token index

Returns:

the correspondent IToken.

Since:

3.0

getTokenText

@Deprecated
protected java.lang.String getTokenText(int i)

Deprecated.

Parameters:

i - the right hand side token index

getRhsTokenText

protected java.lang.String getRhsTokenText(int i)

A convenience method to obtain the text of a right hand side IToken.

Parameters:

i - the right hand side token index

Since:

3.0

reportErrorTokenMessage

protected final void reportErrorTokenMessage(int error_token,
                                             java.lang.String msg)

Report error message for given error_token.

Parameters:

error_token - the error taken index

msg - the message to report

Since:

1.3
