ChildSessionParams is an abstract class that represents proposed configurations for negotiating a Child Session.
Note that references to negotiated configurations will be held, and the same parameters will be reused during rekey. This includes SA Proposals, lifetimes and traffic selectors.
IKE library will send out KE payload only if user has configured one or more DH groups. The KE payload in a request will use the first DH group from the first user provided SA proposal (or the peer selected SA proposal if it's a rekey request). The KE payload in a response will depend on the SA proposal negotiation result.
When requesting the first Child Session in IKE AUTH, IKE library will not propose any DH group even if user has configured it, as per RFC 7296. When rekeying this child session, IKE library will accept DH groups that are configured in its ChildSessionParams. If after rekeying user needs to have the same DH group as that of the IKE Session, then they need to explicitly set the same DH Group in ChildSessionParams.

Public methods
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
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.
| Parameters | |
|---|---|
o |
Object: the reference object with which to compare. |
| Returns | |
|---|---|

true if this object is the same as the obj
argument; false otherwise. |

getSoftLifetimeSeconds
public int getSoftLifetimeSeconds ()

| Returns | |
|---|---|

hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap.
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
equals(java.lang.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.)
