An index refers to a single table or view in a database. Information about the fields that comprise the index can be used to generate SQL statements.
Constructs a copy of other.
Constructs an empty index using the cursor name cursorname and index name name.
Sets the index equal to other.
Destroys the object and frees any allocated resources.
Appends the field field to the list of indexed fields. The field is appended with an ascending sort order.
This is an overloaded function.
Appends the field field to the list of indexed fields. The field is appended with an ascending sort order, unless desc is true.
Returns the name of the cursor which the index is associated with.
See also setCursorName().
true if field i in the index is sorted in descending order; otherwise returns
Returns the name of the index.
See also setName().
Sets the name of the cursor that the index is associated with to cursorName.
See also cursorName().
If desc is true, field i is sorted in descending order. Otherwise, field i is sorted in ascending order (the default). If the field does not exist, nothing happens.
See also isDescending().
Sets the name of the index to name.
See also name().
