OpenAIQAWithStructureChain<S extends Object> class

A chain that answers questions returning the answers with the specified structure (ToolSpec).

OpenAI functions allows for structuring of response output. This is often useful in question answering when you want the answer to be returned with a specific structure (e.g. the answer and the sources used to answer the question).

Properties

chainType → String
Return the string type key uniquely identifying this class of chain.
no setterinherited
defaultOptions → ChainOptions
The default options to use when invoking the Runnable.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
inputKeys → Set<String>
Input keys for this chain.
no setterinherited
llm → ChatOpenAI
Language model to call.
finalinherited
llmOptions → ChatOpenAIOptions?
Options to pass to the language model.
finalinherited
memory → BaseChatMemory?
Memory to use for this chain.
finalinherited

Key to use for output.
finalinherited
outputKeys → Set<String>
Output keys for this chain.
no setterinherited
outputParser → BaseOutputParser<Object?, OutputParserOptions, Object?>?
OutputParser to use.
finalinherited
prompt → BasePromptTemplate

Methods

apply(List<ChainValues> inputs) → Future<List<ChainValues>>
Call the chain on all inputs in the list.
inherited
batch(List<ChainValues> inputs, {List<ChainOptions>? options}) → Future<List<ChainValues>>
Batches the invocation of the Runnable on the given inputs.
inherited
bind(ChainOptions options) → RunnableBinding<ChainValues, ChainOptions, ChainValues>
Binds the Runnable to the given options.
inherited
call(dynamic input, {bool returnOnlyOutputs = false}) → Future<ChainValues>
Runs the core logic of this chain with the given values. If memory is not null, it will be used to load and save values.
inherited
callInternal(ChainValues inputs) → Future<ChainValues>
Call method to be implemented by subclasses (called by call). This is where the core logic of the chain should be implemented.
inherited
close() → void
Cleans up any resources associated with it the Runnable.
inherited
getCompatibleOptions(RunnableOptions? options) → ChainOptions?
Returns the given options if they are compatible with the Runnable, otherwise returns null.
inherited
invoke(ChainValues input, {ChainOptions? options}) → Future<ChainValues>
Runs the core logic of this chain with the given input.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
pipe<NewRunOutput extends Object?, NewCallOptions extends RunnableOptions>(Runnable<ChainValues, NewCallOptions, NewRunOutput> next) → RunnableSequence<ChainValues, NewRunOutput>
Pipes the output of this Runnable into another Runnable using a RunnableSequence.
inherited
run(dynamic input) → Future<String>
Convenience method for executing chain when there's a single string output.
inherited
stream(ChainValues input, {ChainOptions? options}) → Stream<ChainValues>
Streams the output of invoking the Runnable on the given input.
inherited
streamFromInputStream(Stream<ChainValues> inputStream, {ChainOptions? options}) → Stream<ChainValues>
Streams the output of invoking the Runnable on the given inputStream.
inherited
toString() → String
A string representation of this object.

operator ==(Object other) → bool
The equality operator.
