 The equals method implements an equivalence relation on non-null object references:
 
- It is reflexive: for any non-null reference value x,x.equals(x)should returntrue.
- It is symmetric: for any non-null reference values xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue.
- It is transitive: for any non-null reference values x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
- It is consistent: for any non-null reference values xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified.
- For any non-null reference value x,x.equals(null)should returnfalse.
 The equals method for class Object implements the most discriminating possible equivalence
 relation on objects; that is, for any non-null reference values x and y, this method returns
 true if and only if x and y refer to the same object (x == y has the value
 true).
 
 Note that it is generally necessary to override the hashCode method whenever this method is overridden,
 so as to maintain the general contract for the hashCode method, which states that equal objects must have
 equal hash codes.
true if this object is the same as the obj argument; false otherwise.The returned value is and exclusive offset.
The default implementation returns
getOffset() + getLength()
The length defines how many characters a token take up in the source code.
A token length may be zero.
The offset is zero based and inclusive.
The type can be an arbitrary string, in relation with the enclosing script model.
 The general contract of hashCode is:
 
- Whenever it is invoked on the same object more than once during an execution of a Java application, the
 hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the equals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the
 Object.equals(Object) method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
 As much as is reasonably practical, the hashCode method defined by class Object does return distinct
 integers for distinct objects. (This is typically implemented by converting the internal address of the object
 into an integer, but this implementation technique is not required by the Java™ programming language.)
The default implementation simply checks if ScriptToken.getLength() is zero.
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())
