Class StringReader
- Closeable, Readable
This class permits a
String to be read as a character
input stream.
The mark/reset functionality in this class behaves differently than
normal. If no mark has been set, then calling the
reset()
method rewinds the read pointer to the beginning of the
String.
StringReader(String buffer)- Create a new
StringReader that will read chars from the
passed in String.
|
void | close()- Closes the stream represented by this class, thus freeing
system resources.

void | mark(int readAheadLimit)

boolean | markSupported()

int | read()

int | read(char[] b, int off, int len)
|
boolean | ready()- This method determines if the stream is ready to be read.
|
void | reset()- Sets the read position in the stream to the previously
marked position or to 0 (i.e., the beginning of the stream) if the mark
has not already been set.
|
long | skip(long n)- This method attempts to skip the requested number of chars in the
input stream.

StringReader
public StringReader(String buffer)
Create a new StringReader that will read chars from the
passed in String. This stream will read from the beginning
to the end of the String.
buffer - The String this stream will read from.
close
public void close()
Closes the stream represented by this class, thus freeing
system resources. In that case that the stream is already
in the closed state, this method has no effect.
- close in interface Closeable
- close in interface Reader
ready
public boolean ready()
throws IOException This method determines if the stream is ready to be read. This class
is always ready to read and so always returns true, unless
close() has previously been called in which case an IOException is
thrown.
- ready in interface Reader
true to indicate that this object is ready to be read.
reset
public void reset()
throws IOException Sets the read position in the stream to the previously
marked position or to 0 (i.e., the beginning of the stream) if the mark
has not already been set.
- reset in interface Reader
skip
public long skip(long n)
throws IOException This method attempts to skip the requested number of chars in the
input stream. It does this by advancing the pos value by
the specified number of chars. It this would exceed the length of the
buffer, then only enough chars are skipped to position the stream at
the end of the buffer. The actual number of chars skipped is returned.
- skip in interface Reader
n - The requested number of chars to skip
- The actual number of chars skipped.
