NAME

Treex::Block::Read::BaseTextReader - abstract ancestor for document readers

VERSION

version 2.20210102

DESCRIPTION

This class serves as an common ancestor for document readers, that have parameter from with a space or comma separated list of filenames to be loaded and load the documents from plain text files. It is designed to implement the Treex::Core::DocumentReader interface.

In derived classes you need to define the next_document method, and you can use next_document_text and new_document methods.

ATTRIBUTES

language (required)

lines_per_doc

If you want to split one file to more documents. The default is 0 which means, don't split.

merge_files

Merge the content of all files (specified in from attribute) into one stream. Useful in combination with lines_per_doc to get equally-sized documents even from non-equally-sized files.

encoding

What is the encoding of the input files. E.g. utf8 (the default), cp1250 etc.

METHODS

next_document_text

Returns a content of each file (specified in from attribute) as a text string.

next_filehandle

Helper method - you can use this instead of next_document_text if you don't want to load the whole text into memory (but do e.g. SAX-like parsing).
