• init(chunkSize:chunkOverlap:wordThreshold:mode:)

  Initializes the default text chunker with a chunk size, chunk overlap, word threshold, and chunking mode.

  Declaration

  Swift

  init(chunkSize: Int, chunkOverlap: Int, wordThreshold: Int, mode: ChunkingMode) throws

• chunkOverlap

  The chunk overlap to use for text chunking. Used only in character-based chunking.

  Declaration

  Swift

  var chunkOverlap: Int { get }

• chunkSize

  Declaration

  Swift

  var chunkSize: Int { get }

• mode

  Mode for text chunking.

  Declaration

  Swift

  var mode: ChunkingMode { get }

• wordThreshold

  The word threshold to use for text chunking. Used only in word-based chunking.
