EvCharSpan Interface

The EvCharSpan TS interface defines a blueprint of a JS object that specifies a continuous range of characters in a text.

Properties

An EvCharSpan object has the following properties:

at: number;

A number, the index of a character in a text from which the given range of characters begins. The index of the first character in the text is 0.

optional count: number;

A number, the number of characters in the given range of characters, including the first character specified in the at property.

A negative number indicates the last character (the end) of the text.

An empty range is defined with 0. It is used to indicate a position in the text, for example, to insert some text without replacing the existing content.

The default value is 1, e.i., the character given in the at property.

Examples

{
    at: 3, 
    count: 0
}
