- class langchain_community.document_loaders.base.BaseBlobParser[source]¶
Abstract interface for blob parsers.
A blob parser provides a way to parse raw data stored in a blob into one or more documents.
The parser can be composed with blob loaders, making it easy to reuse a parser independent of how the blob was originally loaded.
