IDicomStream

public class DicomBufferStream
extends DicomStream

This class specifies Input/Output and Buffer Stream to perform reading/writing operations on the byte array. For example: To read from a buffer stream in which ByteArrayInputStream is set: ByteArrayInputStream bais = new ByteArrayInputStream(); DicomStream ds = new BufferStream(); ds.setInputStream(bais); int i = ds.readInt(); ds.close(); To write to a file stream in which ByteArrayOutputStream is set: FileOutputStream fis = new FileOutputStream("t.tmp"); DicomStream ds = new FileStream(); ds.setOutputStream(fis); int i = 20; ds.writeInt(i); ds.close(); BufferStream can act as input stream as well as output stream at the same time by using setStream(inpustream,outputstream) method. In this case, programmer can use it for reading as well as writing also. BufferStream inherits default functionality of mark, reset and skipping of bytes over the underlying input stream.

Method Detail

setInputStream

public int setInputStream(java.io.ByteArrayInputStream objByteArrayInputStream)

Sets the Input Stream.

Parameters:

objByteArrayInputStream - Object of ByteArrayInputStream.

Returns:

int - Integer value shows success.

setOutputStream

public int setOutputStream(java.io.ByteArrayOutputStream objByteArrayOutputStream)

Sets the Output Stream.

Parameters:

objByteArrayOutputStream - Object of ByteArrayOutputStream.
