BBjString::indexOf

Description

In BBj 7.0 and higher, this method returns the index within this string of the first occurrence of the specified character. If a character with value ch occurs in the character sequence represented by this String object, then the index (in Unicode code units) of the first such occurrence is returned. For values of ch in the range from 0 to 0xFFFF (inclusive), this is the smallest value k such that:

is true. For other values of ch, it is the smallest value k such that:

this.charAt(k) == ch

is true. For other values of ch, it is the smallest value k such that:

this.codePointAt(k) == ch

is true. In either case, if no such character occurs in this string, then -1 is returned.

Syntax

Return Value	Method
int	indexOf(int ch)
int	indexOf(int ch, int fromIndex)
int	indexOf(string str)
int	indexOf(string str, int fromIndex)

Parameters

Variable	Description
ch	A character (Unicode code point).
fromIndex	The index to start the search from.
str	The substring to search for.

Return Value

Returns the index of the first occurrence of the character in the character sequence represented by this string, or -1 if the character does not occur.

Remarks

None.
