appendWriteln

 

 

Overview

The appendWriteln Function converts one or more arguments to strings and appends them to the end of a target Byte Vector and returns the result. The appendWriteln operation is destructive, that is the result of appending changes the contents of the target Byte Vector. The arguments are converted into strings and concatenated from left to right, returning the final appended Byte Vector. If only the Byte Vector is specified, it is returned.

Usage

Use the appendWriteln function to concatenate large strings into a preallocated space. This will be faster than multiple appends, which may involve multiple garbage collections, as the required space grows in size.

 

Syntax

Expression:

(appendWriteln ByteVector...)

Arguments Name Type Description
Argument:ByteVectorByteVector A preallocated Byte Vector argument, with enough size to contain the final appended string, is mandatory. It can be followed by a list of arguments, each of which will be converted to a string and concatenated into the specified Byte Vector.

Returns:

The Byte Vector, after the append, is returned.
