ByteArrayOutputStream

ByteArrayOutputStream

ByteArrayOutputStream()

Creates a new ByteArrayOutputStream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

ByteArrayOutputStream

ByteArrayOutputStream(size: Int)

Creates a new ByteArrayOutputStream, with a buffer capacity of the specified size, in bytes.

close

open fun close(): Unit

Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

reset

open fun reset(): Unit

Resets the count field of this ByteArrayOutputStream 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.

size

open fun size(): Int

Returns the current size of the buffer.

toByteArray

open fun toByteArray(): ByteArray

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.

toString

open fun toString(): String

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 java.nio.charset.CharsetDecoder class should be used when more control over the decoding process is required.

toString

open fun toString(charsetName: String): String

Converts the buffer's contents into a string by decoding the bytes using the named charset.

This method is equivalent to toString(charset) that takes a charset.

An invocation of this method of the form

<code>ByteArrayOutputStream b = ...
       b.toString("UTF-8")
       </code>

<code>ByteArrayOutputStream b = ...
       b.toString(StandardCharsets.UTF_8)
       </code>

toString

open fun toString(charset: Charset): String

Converts the buffer's contents into a string by decoding the bytes using the specified charset. 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 the charset's default replacement string. The class should be used when more control over the decoding process is required.

toString

open fun toString(hibyte: Int): String

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(java.lang.String) or toString(java.nio.charset.Charset) method, which takes an encoding-name or charset 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:

<code>c == (char)(((hibyte &amp; 0xff) &lt;&lt; 8) | (b &amp; 0xff))
  </code>

write

open fun write(b: Int): Unit

Writes the specified byte to this ByteArrayOutputStream.

write

open fun write(
    b: ByteArray, 
    off: Int, 
    len: Int
): Unit

Writes len bytes from the specified byte array starting at offset off to this ByteArrayOutputStream.

writeBytes

open fun writeBytes(b: ByteArray!): Unit

Writes the complete contents of the specified byte array to this ByteArrayOutputStream.

writeTo

open fun writeTo(out: OutputStream): Unit

Writes the complete contents of this ByteArrayOutputStream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count).

buf

protected var buf: ByteArray

The buffer where data is stored.

count

protected var count: Int

The number of valid bytes in the buffer.
