Inherited methods

Public constructors

Builder

Added in API level 31
public Builder ()

Create a Builder for negotiating a tunnel mode Child Session.

Builder

Added in API level 31
public Builder (TunnelModeChildSessionParams childParams)

Construct Builder from the TunnelModeChildSessionParams object.

Parameters
childParams TunnelModeChildSessionParams: the object this Builder will be constructed with. This value cannot be null.

Public methods

addChildSaProposal

Added in API level 31
public TunnelModeChildSessionParams.Builder addChildSaProposal (ChildSaProposal proposal)

Adds an Child SA proposal to the TunnelModeChildSessionParams being built.

Parameters
proposal ChildSaProposal: Child SA proposal. This value cannot be null.

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInboundTrafficSelectors

Added in API level 31
public TunnelModeChildSessionParams.Builder addInboundTrafficSelectors (IkeTrafficSelector trafficSelector)

Adds an inbound IkeTrafficSelector to the TunnelModeChildSessionParams being built.

This method allows callers to limit the inbound traffic transmitted over the Child Session to the given range. The IKE server may further narrow the range. Callers should refer to ChildSessionConfiguration for the negotiated traffic selectors.

If no inbound IkeTrafficSelector is provided, a default value will be used that covers all IP addresses and ports.

Parameters
trafficSelector IkeTrafficSelector: the inbound IkeTrafficSelector. This value cannot be null.

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInternalAddressRequest

Added in API level 31
public TunnelModeChildSessionParams.Builder addInternalAddressRequest (int addressFamily)

Adds an internal IP address request to the TunnelModeChildSessionParams being built.

Parameters
addressFamily int: the address family. Only AF_INET and AF_INET6 are allowed

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInternalAddressRequest

Added in API level 31
public TunnelModeChildSessionParams.Builder addInternalAddressRequest (Inet4Address address)

Adds a specific internal IPv4 address request to the TunnelModeChildSessionParams being built.

Parameters
address Inet4Address: the requested IPv4 address. This value cannot be null.

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInternalAddressRequest

Added in API level 31
public TunnelModeChildSessionParams.Builder addInternalAddressRequest (Inet6Address address, 
                int prefixLen)

Adds a specific internal IPv6 address request to the TunnelModeChildSessionParams being built.

Parameters
address Inet6Address: the requested IPv6 address. This value cannot be null.

prefixLen int: length of the IPv6 address prefix length.

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInternalDhcpServerRequest

Added in API level 31
public TunnelModeChildSessionParams.Builder addInternalDhcpServerRequest (int addressFamily)

Adds an internal DHCP server request to the TunnelModeChildSessionParams being built.

Only DHCPv4 server requests are supported.

Parameters
addressFamily int: the address family. Only AF_INET is allowed

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addInternalDnsServerRequest

Added in API level 31
public TunnelModeChildSessionParams.Builder addInternalDnsServerRequest (int addressFamily)

Adds an internal DNS server request to the TunnelModeChildSessionParams being built.

Parameters
addressFamily int: the address family. Only AF_INET and AF_INET6 are allowed

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

addOutboundTrafficSelectors

Added in API level 31
public TunnelModeChildSessionParams.Builder addOutboundTrafficSelectors (IkeTrafficSelector trafficSelector)

Adds an outbound IkeTrafficSelector to the TunnelModeChildSessionParams being built.

This method allows callers to limit the outbound traffic transmitted over the Child Session to the given range. The IKE server may further narrow the range. Callers should refer to ChildSessionConfiguration for the negotiated traffic selectors.

If no outbound IkeTrafficSelector is provided, a default value will be used that covers all IP addresses and ports.

Parameters
trafficSelector IkeTrafficSelector: the outbound IkeTrafficSelector. This value cannot be null.

Returns
TunnelModeChildSessionParams.Builder Builder this, to facilitate chaining. This value cannot be null.

build

Added in API level 31
public TunnelModeChildSessionParams build ()

Validates and builds the TunnelModeChildSessionParams.

Returns
TunnelModeChildSessionParams the validated TunnelModeChildSessionParams. This value cannot be null.

setLifetimeSeconds

Added in API level 31
public TunnelModeChildSessionParams.Builder setLifetimeSeconds (int hardLifetimeSeconds, 
                int softLifetimeSeconds)

Sets hard and soft lifetimes.

Lifetimes will not be negotiated with the remote IKE server.

Parameters
hardLifetimeSeconds int: number of seconds after which Child SA will expire. Defaults to 7200 seconds (2 hours). Considering IPsec packet lifetime, IKE library requires hard lifetime to be a value from 300 seconds (5 minutes) to 14400 seconds (4 hours), inclusive. Value is between CHILD_HARD_LIFETIME_SEC_MINIMUM and CHILD_HARD_LIFETIME_SEC_MAXIMUM inclusive

softLifetimeSeconds int: number of seconds after which Child SA will request rekey. Defaults to 3600 seconds (1 hour). MUST be at least 120 seconds (2 minutes), and at least 60 seconds (1 minute) shorter than the hard lifetime. Value is between CHILD_SOFT_LIFETIME_SEC_MINIMUM and CHILD_HARD_LIFETIME_SEC_MAXIMUM inclusive

Returns
TunnelModeChildSessionParams.Builder This value cannot be null.
