IsEmpty

Reports whether anything has been written.

Module: Text

Signature

func IsEmpty(self) -> bool;

Returns

true when Length is 0.

It says nothing about the Capacity: a builder that has been Cleared is empty but still holds its block, and so is one built with WithCapacity that has not been appended to.

Example

import Text::StringBuilder;

var builder = StringBuilder::WithCapacity(64);
builder.IsEmpty();  // true -- room reserved, nothing written

builder.Append("Rux");
builder.IsEmpty();  // false

builder.Clear();
builder.IsEmpty();  // true, and the 64 bytes are still there

builder.Free();
