Indicates whether some other object is "equal to" this one.
Gets the current mode in which the derivatives are to be evaluated.
Gets the array representing the current derivatives of the dependent variables.

Gets the current values of the dependent variables.
Returns a hash code value for the object.

epoch- The time at which the independent variable is zero.
epochSeconds- The seconds elapsed since the propagation
state- The current overall state, including memory for storing the auxiliary variables.
derivatives- The current derivatives of the dependent variables in the state (not including auxiliary variables). This is set by the derivative evaluators during integration.

equals method for class
the most discriminating possible equivalence relation on objects;

Note that it is generally necessary to override the
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.

The general contract of
hashCodemethod must consistently return the same integer, provided no information used in
equalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
equals(Object)method, then calling the
hashCodemethod on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)method, then calling the
hashCodemethod 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
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.)
