AbstractCharSequence

public AbstractCharSequence()

Method Detail

length

public abstract int length()

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

Specified by:

length in interface CharSequence

Returns:

the number of characters in this sequence

---

charAt

public abstract char charAt(int index)

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.

Specified by:

charAt in interface CharSequence

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)

Return subsequence of this character sequence. The returned character sequence is only as stable as is this character sequence.

Specified by:

subSequence in interface CharSequence

Parameters:

start - >=0 starting index of the subsequence within this character sequence.

end - >=0 ending index of the subsequence within this character sequence.

---

toString

public String toString()

Specified by:

toString in interface CharSequence

Overrides:

toString in class Object
