Interface CharSequence

All Known Implementing Classes:

String, StringBuffer

public interface CharSequence

Untamed:

length

public int length()

Enabled: Returns the length of this character sequence. The length is the number of 16-bit Unicode characters in the sequence.

Returns:

the number of characters in this sequence

charAt

public char charAt(int index)

Enabled: Returns the character at the specified index. An index ranges from zero to length() - 1. The first character of the sequence is at index zero, the next at index one, and so on, as for array indexing.

Parameters:

index - the index of the character to be returned

Returns:

the specified character

Throws:

IndexOutOfBoundsException - if the index argument is negative or not less than length()

subSequence

public CharSequence subSequence(int start,
 int end)

Enabled: Returns a new character sequence that is a subsequence of this sequence. The subsequence starts with the character at the specified index and ends with the character at index end - 1. The length of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Parameters:

start - the start index, inclusive

end - the end index, exclusive

Returns:

the specified subsequence

Throws:

IndexOutOfBoundsException - if start or end are negative, if end is greater than length(), or if start is greater than end

toString

public String toString()

Suppressed: Returns a string containing the characters in this sequence in the same order as this sequence. The length of the string will be the length of this sequence.

Overrides:

toString in class Object

Returns:

a string consisting of exactly this sequence of characters
