compareTo

public int compareTo(java.lang.Object o)

Description copied from class: SymbolicObject

Compare two SymbolicObjects. The result is zero if the objects are equal according to the equals() operator. Otherwise, the result is a negative integer if this object's name lexicographically precedes the other's name. The result is a positive integer if this object's name lexicographically follows the other's name.

Specified by:

compareTo in class SymbolicObject

equals

Specified by:

equals in class SymbolicObject
