array of tokens

indexOf

public static int indexOf(java.lang.String src,
                          java.lang.String sub,
                          int startIndex,
                          int endIndex)

Finds first occurrence of a substring in the given source but within limited range [start, end). It is fastest possible code, but still original String.indexOf(String, int) is much faster (since it uses char[] value directly) and should be used when no range is needed.

Parameters:

src - source string for examination

sub - substring to find

startIndex - starting index

endIndex - ending index

Returns:

index of founded substring or -1 if substring not found

indexOf

public static int indexOf(java.lang.String src,
                          char c,
                          int startIndex,

Finds first index of a substring in the given source string with ignored case.

Parameters:

src - source string for examination

subS - substring to find

Returns:

index of founded substring or -1 if substring is not found

See Also:

indexOfIgnoreCase(String, String, int)

indexOfIgnoreCase

public static int indexOfIgnoreCase(java.lang.String src,
                                    java.lang.String subS,
                                    int startIndex)

Finds first index of a substring in the given source string with ignored case. This seems to be the fastest way doing this, with common string length and content (of course, with no use of Boyer-Mayer type of algorithms). Other implementations are slower: getting char array first, lower casing the source string, using String.regionMatch etc.

Parameters:

src - source string for examination

subS - substring to find

startIndex - starting index from where search begins

Returns:

index of founded substring or -1 if substring is not found

Parameters:

src - source string for examination

sub - substring to find
