skip
public long skip(long n) throws java.io.IOException
Skips characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.- Overrides:
skip
in classjava.io.FilterReader
- Parameters:
n
- The number of characters to skip- Returns:
- the number of characters actually skipped
- Throws:
java.lang.IllegalArgumentException
- Ifn
is negative.java.io.IOException
- If an I/O error occurs
-
read
public int read(char[] cbuf, int off, int len) throws java.io.IOException
Reads characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.- Overrides:
read
in classjava.io.FilterReader
- Parameters:
cbuf
- Destination buffer to write characters to. Must not benull
.off
- Offset at which to start storing 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:
java.io.IOException
- If an I/O error occurs
-
read
public int read() throws java.io.IOException
Returns the next character in the filtered stream, replacing tokens from the original stream.- Overrides:
read
in classjava.io.FilterReader
- Returns:
- the next character in the resulting stream, or -1 if the end of the resulting stream has been reached
- Throws:
java.io.IOException
- if the underlying stream throws an IOException during reading
