Class ExposedByteArrayOutputStream

java.lang.Object
java.io.OutputStream
java.io.ByteArrayOutputStream
org.jgroups.util.ExposedByteArrayOutputStream
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
public class ExposedByteArrayOutputStream extends ByteArrayOutputStream
Extends ByteArrayOutputStream, but exposes the internal buffer. This way we don't need to call toByteArray() which copies the internal buffer

  • Constructor Details

    • ExposedByteArrayOutputStream

      public ExposedByteArrayOutputStream()

    • ExposedByteArrayOutputStream

      public ExposedByteArrayOutputStream(int size)

  • 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 class ByteArrayOutputStream

    • write

      public void write(byte[] b, int off, int len)
      Writes len bytes from the specified byte array starting at offset off to this byte array output stream.
      Overrides:
      write in class ByteArrayOutputStream
      Parameters:
      b - the data.
      off - the start offset in the data.
      len - the number of bytes to write.

    • writeTo

      public void writeTo(OutputStream out) throws IOException
      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 using out.write(buf, 0, count).
      Overrides:
      writeTo in class ByteArrayOutputStream
      Parameters:
      out - the output stream to which to write the data.
      Throws:
      IOException - if an I/O error occurs.

    • reset

      public void reset()
      Resets the count 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 class ByteArrayOutputStream
      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 class ByteArrayOutputStream
      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 class ByteArrayOutputStream
      Returns:
      the value of the count field, which is the number of valid bytes in this output stream.
      See Also:

    • toString

      public String 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 class ByteArrayOutputStream
      Returns:
      String decoded from the buffer's contents.
      Since:
      JDK1.1

    • toString

      public String toString(String charsetName) throws UnsupportedEncodingException
      Converts the buffer's contents into a string by decoding the bytes using the specified charsetName. 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 class ByteArrayOutputStream
      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 public String toString(int hibyte)
      Deprecated.
      This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via the toString(String enc) method, which takes an encoding-name argument, or the toString() 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 class ByteArrayOutputStream
      Parameters:
      hibyte - the high byte of each resulting Unicode character.
      Returns:
      the current contents of the output stream, as a string.
