public static final CallOptions DEFAULT
```
    A blank CallOptions that all fields are not set.

  - withAuthority
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1767")
public CallOptions withAuthority(@Nullable
                                                                                                         String authority)
```
    Override the HTTP/2 authority the channel claims to be connecting to. This is not generally safe. Overriding allows advanced users to re-use a single Channel for multiple services, even if those services are hosted on different domain names. That assumes the server is virtually hosting multiple domains and is guaranteed to continue doing so. It is rare for a service provider to make such a guarantee. At this time, there is no security verification of the overridden value, such as making sure the authority matches the server's TLS certificate.
  - withCallCredentials
```
public CallOptions withCallCredentials(@Nullable
                                       CallCredentials credentials)
```
    Returns a new CallOptions with the given call credentials.
  - withCompression
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1704")
public CallOptions withCompression(@Nullable
                                                                                                           String compressorName)
```
    Sets the compression to use for the call. The compressor must be a valid name known in the CompressorRegistry.
    It is only safe to call this if the server supports the compression format chosen. There is no negotiation performed; if the server does not support the compression chosen, the call will fail.
  - withDeadline
```
public CallOptions withDeadline(@Nullable
                                io.grpc.Deadline deadline)
```
    Returns a new CallOptions with the given absolute deadline.
    This is mostly used for propagating an existing deadline. withDeadlineAfter(long, java.util.concurrent.TimeUnit) is the recommended way of setting a new deadline,
    
    Parameters:
    
    deadline - the deadline or null for unsetting the deadline.
  - withDeadlineAfter
```
public CallOptions withDeadlineAfter(long duration,
                                     TimeUnit unit)
```
    Returns a new CallOptions with a deadline that is after the given duration from now.
  - getDeadline
```
@Nullable
public io.grpc.Deadline getDeadline()
```
    Returns the deadline or null if the deadline is not set.
  - withWaitForReady
```
public CallOptions withWaitForReady()
```
    Enables 'wait for ready' feature for the call. 'Fail fast' is the default option for gRPC calls and 'wait for ready' is the opposite to it.
  - withoutWaitForReady
```
public CallOptions withoutWaitForReady()
```
    Disables 'wait for ready' feature for the call. This method should be rarely used because the default is without 'wait for ready'.
  - getCompressor
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1704")
 @Nullable
public String getCompressor()
```
    Returns the compressor's name.
  - getAuthority
```
@Nullable
 @ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1767")
public String getAuthority()
```
    Override the HTTP/2 authority the channel claims to be connecting to. This is not generally safe. Overriding allows advanced users to re-use a single Channel for multiple services, even if those services are hosted on different domain names. That assumes the server is virtually hosting multiple domains and is guaranteed to continue doing so. It is rare for a service provider to make such a guarantee. At this time, there is no security verification of the overridden value, such as making sure the authority matches the server's TLS certificate.
  - getCredentials
```
@Nullable
public CallCredentials getCredentials()
```
    Returns the call credentials.
  - withExecutor
```
public CallOptions withExecutor(@Nullable
                                Executor executor)
```
    Returns a new CallOptions with executor to be used instead of the default executor specified with ManagedChannelBuilder.executor(java.util.concurrent.Executor).
  - withStreamTracerFactory
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2861")
public CallOptions withStreamTracerFactory(ClientStreamTracer.Factory factory)
```
    Returns a new CallOptions with a ClientStreamTracerFactory in addition to the existing factories.
    This method doesn't replace existing factories, or try to de-duplicate factories.
  - getStreamTracerFactories
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2861")
public List<ClientStreamTracer.Factory> getStreamTracerFactories()
```
    Returns an immutable list of ClientStreamTracerFactorys.
  - withOption
```
public <T> CallOptions withOption(CallOptions.Key<T> key,
                                  T value)
```
    Sets a custom option. Any existing value for the key is overwritten.
    
    Parameters:
    
    key - The option key
    
    value - The option value.
    
    Since:
    
    1.13.0
  - getOption
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1869")
public <T> T getOption(CallOptions.Key<T> key)
```
    Get the value for a custom option or its inherent default.
    
    Parameters:
    
    key - Key identifying option
  - getExecutor
```
@Nullable
public Executor getExecutor()
```
  - isWaitForReady
```
public boolean isWaitForReady()
```
    Returns whether 'wait for ready' option is enabled for the call. 'Fail fast' is the default option for gRPC calls and 'wait for ready' is the opposite to it.
  - withMaxInboundMessageSize
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2563")
public CallOptions withMaxInboundMessageSize(int maxSize)
```
    Sets the maximum allowed message size acceptable from the remote peer. If unset, this will default to the value set on the ManagedChannelBuilder.maxInboundMessageSize(int).
  - withMaxOutboundMessageSize
```
@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2563")
public CallOptions withMaxOutboundMessageSize(int maxSize)
```
    Sets the maximum allowed message size acceptable sent to the remote peer.
  - getMaxInboundMessageSize
```
@Nullable
 @ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2563")
public Integer getMaxInboundMessageSize()
```
    Gets the maximum allowed message size acceptable from the remote peer.
  - getMaxOutboundMessageSize
```
@Nullable
 @ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/2563")
public Integer getMaxOutboundMessageSize()
```
    Gets the maximum allowed message size acceptable to send the remote peer.
