[ file->readstring ]

Method

The [file->readString] method reads string data from a file. If a character set has been set using [file->setEncoding] then that character set is used to translate data from the file into Lasso's string format. Alternately, [file->readBytes] can be used to read a byte stream from a file.

The [file] type implements [trait_readString] which provides the [trait_readString->readString] method. This means that you can call [file->readString] with a single parameter which specifies how many bytes of data to read from the file. If this parameter is not specified, the method reads the entire file. In files that contain multi-byte data this number may not correspond to the number of characters which will be read from the file.

  • Syntax
local(f) = file(...)
#f->readString
