org.jgroups.util.ExposedByteArrayOutputStream
- All Implemented Interfaces:
Closeable
,Flushable
,AutoCloseable
Extends ByteArrayOutputStream, but exposes the internal buffer. This way we don't need to call
toByteArray() which copies the internal buffer

Method Details
-
reset
public void reset(int max_size) Resets count and creates a new buf if the current buf is > max_size. This method is not synchronized -
getRawBuffer
public byte[] getRawBuffer() -
getCapacity
public int getCapacity() -
write
public void write(int b) - Overrides:
write
in classByteArrayOutputStream
-
write
public void write(byte[] b, int off, int len) Writeslen
bytes from the specified byte array starting at offsetoff
to this byte array output stream.- Overrides:
write
in classByteArrayOutputStream
- Parameters:
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.
-
writeTo
Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method usingout.write(buf, 0, count)
.- Overrides:
writeTo
in classByteArrayOutputStream
- Parameters:
out
- the output stream to which to write the data.- Throws:
IOException
- if an I/O error occurs.
-
reset
public void reset()Resets thecount
field of this byte array output stream to zero, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.- Overrides:
reset
in classByteArrayOutputStream
- See Also:
-
toByteArray
public byte[] toByteArray()Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.- Overrides:
toByteArray
in classByteArrayOutputStream
- Returns:
- the current contents of this output stream, as a byte array.
- See Also:
-
size
public int size()Returns the current size of the buffer.- Overrides:
size
in classByteArrayOutputStream
- Returns:
- the value of the
count
field, which is the number of valid bytes in this output stream. - See Also:
-
toString
Converts the buffer's contents into a string decoding bytes using the platform's default character set. The length of the new String is a function of the character set, and hence may not be equal to the size of the buffer.This method always replaces malformed-input and unmappable-character sequences with the default replacement string for the platform's default character set. The CharsetDecoder class should be used when more control over the decoding process is required.
- Overrides:
toString
in classByteArrayOutputStream
- Returns:
- String decoded from the buffer's contents.
- Since:
- JDK1.1
-
toString
Converts the buffer's contents into a string by decoding the bytes using the specifiedcharsetName
. The length of the new String is a function of the charset, and hence may not be equal to the length of the byte array.This method always replaces malformed-input and unmappable-character sequences with this charset's default replacement string. The
CharsetDecoder
class should be used when more control over the decoding process is required.- Overrides:
toString
in classByteArrayOutputStream
- Parameters:
charsetName
- the name of a supported charset- Returns:
- String decoded from the buffer's contents.
- Throws:
UnsupportedEncodingException
- If the named charset is not supported- Since:
- JDK1.1
-
toString
Deprecated.This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via thetoString(String enc)
method, which takes an encoding-name argument, or thetoString()
method, which uses the platform's default character encoding.Creates a newly allocated string. Its size is the current size of the output stream and the valid contents of the buffer have been copied into it. Each character c in the resulting string is constructed from the corresponding element b in the byte array such that:c == (char)(((hibyte & 0xff) << 8) | (b & 0xff))
- Overrides:
toString
in classByteArrayOutputStream
- Parameters:
hibyte
- the high byte of each resulting Unicode character.- Returns:
- the current contents of the output stream, as a string.
