Constructors

o StringReader 
    method StringReader(s=String) public
Create a new string reader.

Methods

o read 
    method read() returns int public     Signals IOException
Read a single character.

Returns:
The character read, or -1 if the end of the stream has been reached
Throws: IOException
If an I/O error occurs
Overrides:
read in class Reader
o read 
    method read(cbuf=char[], -
                off=int, -
                len=int) returns int public     Signals IOException
Read characters into a portion of an array.

Parameters:
cbuf - Destination buffer
off - Offset at which to start writing characters
len - Maximum number of characters to read
Returns:
The number of characters read, or -1 if the end of the stream has been reached
Throws: IOException
If an I/O error occurs
Overrides:
read in class Reader
o skip 
    method skip(ns=long) returns long public     Signals IOException
Skip characters.

Throws: IOException
If an I/O error occurs
Overrides:
skip in class Reader
o ready 
    method ready() returns boolean public
Tell whether this stream is ready to be read. String readers are always ready to be read.

Overrides:
ready in class Reader
o markSupported 
    method markSupported() returns boolean public
Tell whether this stream supports the mark() operation, which it does.

Overrides:
markSupported in class Reader
o mark 
    method mark(readAheadLimit=int)  public     Signals IOException
Mark the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.

Parameters:
readAheadLimit - Limit on the number of characters that may be read while still preserving the mark. Because the stream's input comes from a string, there is no actual limit, so this argument is ignored.
Throws: IOException
If an I/O error occurs
Overrides:
mark in class Reader
o reset 
    method reset()  public     Signals IOException
Reset the stream to the most recent mark, or to the beginning of the string if it has never been marked.

Throws: IOException
If an I/O error occurs
Overrides:
reset in class Reader
o close 
    method close()  public
Close the stream.

Overrides:
close in class Reader
