Endofspan

Endofspan is not a standard term with a single, formal definition. In practice, it is most often encountered as a compound name or label used in software and technical discussions to refer to something related to the boundary or end of a span. Because “end” and “span” appear in several domains, the exact meaning of endofspan depends on context.

In computing and text processing, endOfSpan (often written in camelCase or as end_of_span) is commonly used as the name of a function or method. A typical endOfSpan function takes a sequence, a start position, and a span specification (such as a length or an explicit end index) and returns the exclusive end index of the span. Such a function is useful in tokenization, syntax highlighting, annotation, and text editing tools to determine the boundary of a region for processing or styling.

In markup languages such as HTML, a span denotes an inline element represented by the tag <span> with a closing tag </span>. In that context, “the end of the span” refers to the end tag, which marks the end of the inline region affected by the span element. Parsers and editors track end tags to maintain proper nesting and document structure.

In mathematics, span is a standard term for the subspace generated by a set of vectors. There is no formal notion of an “end of span,” since a span is a subspace without a boundary in the usual topological sense. When encountered informally, endofspan may be used only as a shorthand label in specific discussions, but precise language (such as “the span generated by S”) is preferred.
