DO NOT USE. This tag is ambiguous. For database cursors (that let you traverse records), use the [database-cursor] tag. For mouse cursors (onscreen pointer to let you know where the mouse is), use [mouse-cursor]. For text-cursors (blinking vertical bar to let you know where text will be input), use [caret].
cursor
can mean many things, and it is recommended to use more specific tags.
- For database cursors (that let you traverse records), it is better to use database-cursor.
- For mouse cursors (onscreen pointer to let you know where the mouse is), it is better to use mouse-cursor.
- For text-cursors (blinking vertical bar to let you know where text will be input), it is better to use caret.
For the database concept, quoting from the wikipedia page:
In computer science and technology, a database cursor is a control structure that enables traversal over the records in a database. Cursors facilitate subsequent processing in conjunction with the traversal, such as retrieval, addition and removal of database records. The database cursor characteristic of traversal makes cursors akin to the programming language concept of iterator.
Cursors are used by database programmers to process individual rows returned by database system queries. Cursors enable manipulation of whole result sets at once—a capability that most procedural programming languages lack. In this scenario, a cursor enables the rows in a result-set to be processed sequentially.
And for the user-interface concept, again from the wikipedia page:
In computing, a cursor is an indicator used to show the position on a computer monitor or other display device that will respond to input from a text input or pointing device. The flashing text cursor may be referred to as a caret in some cases.
