readByte
method of DataInput
. Bytes for this operation are read from the contained input stream.
@return the next byte of this input stream as a signed 8-bitbyte
.
@exception EOFException if this input stream has reached the end.
@exception IOException the stream has been closed and the containedinput stream does not support reading after close, or another I/O error occurs.
@see java.io.FilterInputStream#in
ObjectOutputStream.writeByte()
@throws IOException If an IO exception happened when reading the primitive data.
byte
value. Byte values between 0x00
and 0x7f
represent integer values between 0
and 127
. Values between 0x80
and 0xff
represent negative values from -128
to /1
. The bit offset within the stream is reset to zero before the read occurs. @return a signed byte value from the stream. @exception java.io.EOFException if the end of the stream is reached. @exception IOException if an I/O error occurs.
SQLInputImpl
object as a byte
in the Java programming language. This method does not perform type-safe checking to determine if the returned type is the expected type; this responsibility is delegated to the UDT mapping as defined by a SQLData
implementation.
@return the next attribute in this SQLInputImpl
object;if the value is SQL NULL
, return null
@throws SQLException if the read position is located at an invalidposition or if there are no further values in the stream
byte
@throws JMSException if the JMS provider fails to read the message due to some internal error.
@throws MessageEOFException if unexpected end of bytes stream has been reached.
@throws MessageNotReadableException if the message is in write-only mode.
byte
value from the stream message.
@return the next byte from the stream message as a 8-bitbyte
@throws JMSException if the JMS provider fails to read the messagedue to some internal error.
@throws MessageEOFException if unexpected end of message stream hasbeen reached.
@throws MessageFormatException if this type conversion is invalid.
@throws MessageNotReadableException if the message is in write-onlymode.
byte
@throws JMSException if the JMS provider fails to read the message due tosome internal error.
@throws MessageEOFException if unexpected end of bytes stream has beenreached.
@throws MessageNotReadableException if the message is in write-only mode.
byte
value from the stream message.
@return the next byte from the stream message as a 8-bitbyte
@throws JMSException if the JMS provider fails to read the message due tosome internal error.
@throws MessageEOFException if unexpected end of message stream has beenreached.
@throws MessageFormatException if this type conversion is invalid.
@throws MessageNotReadableException if the message is in write-only mode.
byte
@throws JMSException if the JMS provider fails to read the message due to some internal error.
@throws MessageEOFException if unexpected end of bytes stream has been reached.
@throws MessageNotReadableException if the message is in write-only mode.
byte
value from the stream message.
@return the next byte from the stream message as a 8-bitbyte
@throws JMSException if the JMS provider fails to read the messagedue to some internal error.
@throws MessageEOFException if unexpected end of message stream hasbeen reached.
@throws MessageFormatException if this type conversion is invalid.
@throws MessageNotReadableException if the message is in write-onlymode.
DataInput
byte
from the payload.
@return A byte
b
, where 0 <= b <= 255
, then the result is: (byte)(b)
byte
.
@throws EOFException if this file has reached the end.
@throws IOException if an I/O error occurs.
