ConfigChangeRequiresNewPolicyInstance()

CreateChildPolicy()

OrphanablePtr< LoadBalancingPolicy > grpc_core::ChildPolicyHandler::CreateChildPolicy ( const char *  child_policy_name, const grpc_channel_args &  args  )

private

Definition at line 275 of file child_policy_handler.cc.

CreateLoadBalancingPolicy()

OrphanablePtr< LoadBalancingPolicy > grpc_core::ChildPolicyHandler::CreateLoadBalancingPolicy ( const char *  name, LoadBalancingPolicy::Args  args  ) const

virtual

Definition at line 310 of file child_policy_handler.cc.

ExitIdleLocked()

void grpc_core::ChildPolicyHandler::ExitIdleLocked ( )

overridevirtual

Tries to enter a READY connectivity state. This is a no-op by default, since most LB policies never go into IDLE state.

Reimplemented from grpc_core::LoadBalancingPolicy.

Definition at line 257 of file child_policy_handler.cc.

name()

const char* grpc_core::ChildPolicyHandler::name ( ) const

inlineoverridevirtual

Returns the name of the LB policy.

Implements grpc_core::LoadBalancingPolicy.

Definition at line 44 of file child_policy_handler.h.

ResetBackoffLocked()

void grpc_core::ChildPolicyHandler::ResetBackoffLocked ( )

overridevirtual

Resets connection backoff.

Implements grpc_core::LoadBalancingPolicy.

Definition at line 266 of file child_policy_handler.cc.

ShutdownLocked()

void grpc_core::ChildPolicyHandler::ShutdownLocked ( )

overrideprivatevirtual

Shuts down the policy.

Implements grpc_core::LoadBalancingPolicy.

Definition at line 137 of file child_policy_handler.cc.

UpdateLocked()

void grpc_core::ChildPolicyHandler::UpdateLocked ( UpdateArgs  )

overridevirtual

Updates the policy with new data from the resolver. Will be invoked immediately after LB policy is constructed, and then again whenever the resolver returns a new result.

Implements grpc_core::LoadBalancingPolicy.

Definition at line 163 of file child_policy_handler.cc.
