Method Detail

• delta

   final RawMessageDeltaEvent.Delta delta()

• _type

   final JsonValue _type()

  Expected to always return the following:

  JsonValue.from("message_delta")

  However, this method can be useful for debugging and logging (e.g. if the server responded with an unexpected value).

• usage

   final MessageDeltaUsage usage()

  Billing and rate-limit usage.

  Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.

  Under the hood, the API transforms requests into a format suitable for the model. The model's output then goes through a parsing stage before becoming an API response. As a result, the token counts in usage will not match one-to-one with the exact visible content of an API request or response.

  For example, output_tokens will be non-zero, even for an empty string response from Claude.

  Total input tokens in a request is the summation of input_tokens, cache_creation_input_tokens, and cache_read_input_tokens.

• _delta

   final JsonField<RawMessageDeltaEvent.Delta> _delta()

  Returns the raw JSON value of delta.

  Unlike delta, this method doesn't throw if the JSON field has an unexpected type.

• _usage

   final JsonField<MessageDeltaUsage> _usage()

  Returns the raw JSON value of usage.

  Unlike usage, this method doesn't throw if the JSON field has an unexpected type.

• _additionalProperties

   final Map<String, JsonValue> _additionalProperties()

• toBuilder

   final RawMessageDeltaEvent.Builder toBuilder()

• validate

   final RawMessageDeltaEvent validate()

  Validates that the types of all values in this object match their expected types recursively.

  This method is not forwards compatible with new types from the API for existing fields.

• isValid

   final Boolean isValid()

• equals

   Boolean equals(Object other)

• hashCode

   Integer hashCode()

• toString

   String toString()

• builder

   final static RawMessageDeltaEvent.Builder builder()

  Returns a mutable builder for constructing an instance of RawMessageDeltaEvent.

  The following fields are required:

  .delta()
  .usage()
