public class SingleCharSequenceLine extends Object implements Line
Line implementation based on a single CharSequence such as
a StringBuilder or String. The sequence starts with the
content string and ends with the
line ending.
As opposed to this implementation, the SimpleLine consists of two
separate character sequences for content and line ending.
CR, EMPTY_LINE, LF, LINE_ENDING, ZERO| Constructor and Description |
|---|
SingleCharSequenceLine(CharSequence charSequence,
int lineEndingLength)
Constructor with character sequence with the data and the
lineEndingLength indicating whether there is one or two
characters for the line ending. |
SingleCharSequenceLine(CharSequence charSequence,
int offset,
int contentLength,
int lineEndingLength)
Constructor with character sequence with the data and
offset
pointing to the first content character of the line. |
| Modifier and Type | Method and Description |
|---|---|
char |
charAt(int index) |
boolean |
equals(Object obj)
Compares
this line with obj and returns true if
obj is a Line (any subclass) and both lines are
identical. |
String |
getContent()
Returns the contents making up this line, but without the line ending
characters.
|
int |
getContentLength()
Returns the length of the content string returned by
Line.getContent(), which is zero for a line without content and
positive otherwise. |
String |
getLineEnding()
Returns the line ending characters, usually one or two characters such as
"\n" or "\r\n". |
int |
getLineEndingLength()
Returns the length of the line ending string returned by
Line.getLineEnding(), which is usually one or two and sometimes zero
the last line in a file is not terminated with a new line character. |
int |
hashCode()
The hash code for this line, based on the complete line with line ending.

toString()
Returns this line including the line ending characters as a string.

Line"\n" or "\r\n". If the last line in a file is not
terminated with a new line character, the returned string can have zero
length.
The encoding of line endings depends on the source of this line object.
It is a single line feed character (LF="\n") if the source
is a Unix type file, and carriage return followed by line
feed (CR+LF= "\r\n") for lines from a Windows file.
