HL7Stream

public HL7Stream()

Method Detail

getStream

public int getStream()

Returns the stream type to which it is set to [InputStream/outputStream].

Specified by:

getStream in interface IHL7Stream

Returns:

int - returns the stream type which is being used.

getReadBytes

public int getReadBytes()

Tracks bytes read from the stream.

Specified by:

getReadBytes in interface IHL7Stream

Returns:

int - the total no of bytes read

readByte

public byte readByte()

Reads a single byte from the stream.

Specified by:

readByte in interface IHL7Stream

Returns:

byte - returns the byte read

readChar

public char readChar()

Reads a char from the stream.

Specified by:

readChar in interface IHL7Stream

Returns:

char - Character read from stream - '\0' if no character is read

readString

public int readString(java.lang.StringBuffer strBuffValue,
             int iCount)

Reads a string from the stream with specified length.

Specified by:

readString in interface IHL7Stream

Parameters:

strBuffValue - length of the string to be read

iCount - specified length

Returns:

int - the read string

writeString

public int writeString(java.lang.String strValue)

Writes the string specified in the parameter on the stream.

Specified by:

writeString in interface IHL7Stream

Parameters:

strValue - the String to write

Returns:

int - Success\Fail

readBuffer

public int readBuffer(byte[] arrbyte)

Reads buffer byte by byte from stream.

Specified by:

readBuffer in interface IHL7Stream

Parameters:

arrbyte - byte of buffer

Returns:

iNumberOfBytesRead - Returns the number of bytes actually read from input stream
If no byte is available because the stream is at end of file, the value -1 is returned.
