接口 DocumentSplitter

public interface DocumentSplitter
Defines the interface for splitting a document into text segments. This is necessary as LLMs have a limited context window, making it impossible to send the entire document at once. Therefore, the document should first be split into segments, and only the relevant segments should be sent to LLM.
DocumentSplitters.recursive() from a dev.langchain4j:langchain4j module is a good starting point.
