addOption

public void addOption(Option o)

addRule

public void addRule(Rule r)

expandInPlace

public void expandInPlace()

Copy all nonoverridden rules, vocabulary, and options into this grammar from supergrammar chain. The change is made in place; e.g., this grammar's vector of rules gets bigger. This has side-effects: all grammars on path to root of hierarchy are expanded also.

toString

public String toString()

Description copied from class: Object

Suppressed: Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
