Throws an IOException if the stream has been closed. Subclasses may call this method from any of their methods that require the stream not to be closed.

Throws:
IOException sample code for java.io.IOException definition code for java.io.IOException - if the stream is closed.

setByteOrder sample code for javax.imageio.stream.ImageInputStreamImpl.setByteOrder(java.nio.ByteOrder) definition code for javax.imageio.stream.ImageInputStreamImpl.setByteOrder(java.nio.ByteOrder)

Description copied from interface: ImageInputStream sample code for javax.imageio.stream.ImageInputStream.setByteOrder(java.nio.ByteOrder) definition code for javax.imageio.stream.ImageInputStream.setByteOrder(java.nio.ByteOrder)
Sets the desired byte order for future reads of data values from this stream. For example, the sequence of bytes '0x01 0x02 0x03 0x04' if read as a 4-byte integer would have the value '0x01020304' using network byte order and the value '0x04030201' under the reverse byte order.

The enumeration class java.nio.ByteOrder is used to specify the byte order. A value of ByteOrder.BIG_ENDIAN specifies so-called big-endian or network byte order, in which the high-order byte comes first. Motorola and Sparc processors store data in this format, while Intel processors store data in the reverse ByteOrder.LITTLE_ENDIAN order.

The byte order has no effect on the results returned from the readBits method (or the value written by ImageOutputStream.writeBits).

Description copied from interface: DataInput sample code for java.io.DataInput.readLine() definition code for java.io.DataInput.readLine()
Reads the next line of text from the input stream. It reads successive bytes, converting each byte separately into a character, until it encounters a line terminator or end of file; the characters read are then returned as a String. Note that because this method processes bytes, it does not support input of the full Unicode character set.

If end of file is encountered before even one byte can be read, then null is returned. Otherwise, each byte that is read is converted to type char by zero-extension. If the character '\n' is encountered, it is discarded and reading ceases. If the character '\r' is encountered, it is discarded and, if the following byte converts to the character '\n', then that is discarded also; reading then ceases. If end of file is encountered before either of the characters '\n' and '\r' is encountered, reading ceases. Once reading has ceased, a String is returned that contains all the characters read and not discarded, taken in order. Note that every character in this string will have a value less than \u0100, that is, (char)256.

public String sample code for java.lang.String definition code for java.lang.String  readUTF()

Description copied from interface: DataInput sample code for java.io.DataInput.readUTF() definition code for java.io.DataInput.readUTF()
Reads in a string that has been encoded using a modified UTF-8 format. The general contract of readUTF is that it reads a representation of a Unicode character string encoded in modified UTF-8 format; this string of characters is then returned as a String.

First, two bytes are read and used to construct an unsigned 16-bit integer in exactly the manner of the readUnsignedShort method . This integer value is called the UTF length and specifies the number of additional bytes to be read. These bytes are then converted to characters by considering them in groups. The length of each group is computed from the value of the first byte of the group. The byte following a group, if any, is the first byte of the next group.

If the first byte of a group matches the bit pattern 0xxxxxxx (where x means "may be 0 or 1"), then the group consists of just that byte. The byte is zero-extended to form a character.

If the first byte of a group matches the bit pattern 110xxxxx, then the group consists of that byte a and a second byte b. If there is no byte b (because byte a was the last of the bytes to be read), or if byte b does not match the bit pattern 10xxxxxx, then a UTFDataFormatException is thrown. Otherwise, the group is converted to the character:

(char)(((a& 0x1F) << 6) | (b & 0x3F))
If the first byte of a group matches the bit pattern 1110xxxx, then the group consists of that byte a and two more bytes b and c. If there is no byte c (because byte a was one of the last two of the bytes to be read), or either byte b or byte c does not match the bit pattern 10xxxxxx, then a UTFDataFormatException is thrown. Otherwise, the group is converted to the character:


 (char)(((a & 0x0F) << 12) | ((b & 0x3F) << 6) | (c & 0x3F))
If the first byte of a group matches the pattern 1111xxxx or the pattern 10xxxxxx, then a UTFDataFormatException is thrown.

If end of file is encountered at any time during this entire process, then an EOFException is thrown.

After every group has been converted to a character by this process, the characters are gathered, in the same order in which their corresponding groups were read from the input stream, to form a String, which is returned.

The writeUTF method of interface DataOutput may be used to write data that is suitable for reading by this method.

Description copied from interface: ImageInputStream sample code for javax.imageio.stream.ImageInputStream.readBit() definition code for javax.imageio.stream.ImageInputStream.readBit()

Specified by:

public long readBits(int numBits)
              throws IOException sample code for java.io.IOException definition code for java.io.IOException
Description copied from interface: ImageInputStream sample code for javax.imageio.stream.ImageInputStream.readBits(int) definition code for javax.imageio.stream.ImageInputStream.readBits(int)
Reads a bitstring from the stream and returns it as a long, with the first bit read becoming the most significant bit of the output. The read starts within the byte indicated by getStreamPosition, at the bit given by getBitOffset. The bit offset is advanced by numBits and reduced modulo 8.

The byte order of the stream has no effect on this method. The return value of this method is constructed as though the bits were read one at a time, and shifted into the right side of the return value, as shown by the following pseudo-code: 

 long accum = 0L;
 for (int i = 0; i < numBits; i++) {
   accum <<= 1; // Shift left one bit to make room
   accum |= readBit();
 }
Note that the result of readBits(32) may thus not be equal to that of readInt() if a reverse network byte order is being used (i.e., getByteOrder() == false).

If the end of the stream is encountered before all the bits have been read, an EOFException is thrown.

Parameters:
numBits - the number of bits to read, as an int between 0 and 64, inclusive.
Returns:
the bitstring, as a long with the last bit read stored in the least significant bit.
Throws:
