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
