RequestStream

public class RequestStream (Code)

Class to implement an output stream for the server request.

Implementation note:

This class contains methods to write different types of data to the server request stream in TDS format.
Character translation of String items is carried out.

Constructor Detail

RequestStream
RequestStream(SharedSocket socket, int streamId, int bufferSize, int maxPrecision)(Code)
	Construct a RequestStream object. Parameters: socket - the shared socket object to write to Parameters: streamId - the unique id for this stream Parameters: bufferSize - the initial buffer size to use (the current networkpacket size) Parameters: maxPrecision - the maximum precision for numeric/decimal types

Method Detail

close
void close()(Code)
	Close the output stream.

flush
void flush() throws IOException(Code)
	Flush the packet to the output stream setting the last packet flag. throws: IOException -

getBufferSize
int getBufferSize()(Code)
	Retrieve the current output packet size. the packet size as an `int`.

getMaxDecimalBytes
byte getMaxDecimalBytes()(Code)
	Returns the maximum number of bytes required to output a decimal given the current RequestStream.maxPrecision . the maximum number of bytes required to output a decimal.

getMaxPrecision
int getMaxPrecision()(Code)
	Retrive the maximum decimal precision. The precision as an `int`.

getServerType
int getServerType()(Code)
	Retrieve the Server type. The Server type as an `int`.

getStreamId
int getStreamId()(Code)
	Retrieve the unique stream id. the unique stream id as an `int`.

getTdsVersion
int getTdsVersion()(Code)
	Retrieve the TDS version number. The TDS version as an `int`.

setBufferSize
void setBufferSize(int size)(Code)
	Set the output buffer size Parameters: size - The new buffer size (>= TdsCore.MIN_PKT_SIZE <= TdsCore.MAX_PKT_SIZE).

setPacketType
void setPacketType(byte pktType)(Code)
	Set the current output packet type. Parameters: pktType - The packet type eg TdsCore.QUERY_PKT.

write
void write(byte[] b) throws IOException(Code)
	Write an array of bytes to the output stream. Parameters: b - The byte array to write. throws: IOException -

write
void write(byte[] b, int off, int len) throws IOException(Code)
	Write a partial byte buffer to the output stream. Parameters: b - The byte array buffer. Parameters: off - The offset into the byte array. Parameters: len - The number of bytes to write. throws: IOException -

write
void write(int i) throws IOException(Code)
	Write an int value to the output stream. Parameters: i - The int value to write. throws: IOException -

write
void write(short s) throws IOException(Code)
