The class supports reading characters from a stream.
| Property | Description |
|---|---|
(read-only) | The method reads the whole input stream, parses it and returns a list of strings. |
(read-only) | The method reads the whole input stream as one string and returns it. |
| Constructor | Description |
|---|---|
| Reader(String) | Creates a reader from a string. |
| Reader(InputStream) | Create a reader from a stream using UTF-8 character encoding. |
| Reader(InputStream, String) | Create a reader from a stream using the specified character encoding. |
| Method | Description |
|---|---|
| close() | Closes the reader. |
| The method reads the whole input stream, parses it and returns a list of strings. | |
| The method reads the whole input stream as one string and returns it. | |
| read() | Reads a single character from the stream. |
| Reads multiple characters from the stream as string. | |
| readLine() | Reads the next line. |
| readLines() | The method reads the whole input stream, parses it and returns a list of strings. |
| readN(Number) | Reads n characters from the stream as string. |

(read-only)The method reads the whole input stream, parses it and returns a list of strings.
Using this method on large feeds is inherently unsafe and may lead to an out-of-memory condition. Instead use method readLine() and process one line at a time.
Deprecated:
Use readLines()
Warning
(read-only)The method reads the whole input stream as one string and returns it.
Using this method is unsafe if the length of the input stream is not known and may lead to an out-of-memory condition. Instead use method readN(Number).
Deprecated:
Use readString()
Warning
Creates a reader from a string.
Parameters:
Create a reader from a stream using UTF-8 character encoding.
Parameters:
Create a reader from a stream using the specified character encoding.
Parameters:
Closes the reader.
The method reads the whole input stream, parses it and returns a list of strings.
Using this method on large feeds is inherently unsafe and may lead to an out-of-memory condition. Instead use method readLine() and process one line at a time.
Returns:
Deprecated:
Use readLines()
Warning
The method reads the whole input stream as one string and returns it.
Using this method is unsafe if the length of the input stream is not known and may lead to an out-of-memory condition. Instead use method readN(Number).
Returns:
Throws:
Deprecated:
Use readString()
Warning
Reads a single character from the stream. The method returns null if the end of the stream is reached.
Returns:
Reads multiple characters from the stream as string. The actual number of characters that were read can be determined from the length of the returned string. If the end of the stream is reached and no more characters can be read, the method exits with an exception.
Parameters:
Returns:
Throws:
Deprecated:
use readN(Number) instead which does not throw an exception if the stream is exhausted
Warning
Reads the next line.
Returns:
The method reads the whole input stream, parses it and returns a list of strings.
Using this method on large feeds is inherently unsafe and may lead to an out-of-memory condition. Instead use method readLine() and process one line at a time.
Returns:
Reads n characters from the stream as string. The actual number of characters that were read can be determined from the length of the returned string. If the end of the stream is reached and no more characters can be read, the method returns null.
Parameters:
Returns:
The method reads the whole input stream as one string and returns it.
Using this method is unsafe if the length of the input stream is not known and may lead to an out-of-memory condition. Instead use method readN(Number).
Returns:
Throws:
Identifies if this stream is ready to be read.
Returns:
Skips the specified number of characters in the stream.
Parameters:
