com.saperion.rmi.SerializableStream

All Implemented Interfaces:

Serializable

public class SerializableStream
extends Object

SerializableStream

public SerializableStream(int token,
                          InputStream input,
                          String filename,
                          int element,
                          int bufferSize,
                          boolean doStreaming)

Instantiates a new serializable stream.

Parameters:

token - the token

input - the input

filename - the filename

element - the element

bufferSize - size of buffer chunk

doStreaming - True if streaming option of content data is activated.

SerializableStream

public SerializableStream(int token,
                          InputStream input,
                          String filename,
                          int element,
                          int bufferSize,
                          boolean doStreaming,
                          SerializableStreamContentHandler.ContentHandlers contentHandler)

Instantiates a new serializable stream.

Parameters:

token - the token

input - the input

filename - the filename

element - the element

bufferSize - size of buffer chunk

doStreaming - True if streaming option of content data is activated.

contentHandler - handles the writing of the content when serializing this stream

SerializableStream

public SerializableStream(int token,
                          ContentStream content,
                          int bufferSize)

ContentStream constructor. Supports the content-hash and content-length validation of the given ContentStream.

Parameters:

token - user token

content - content stream to wrap

bufferSize - size of buffer chunk

SerializableStream

public SerializableStream(int token,
                          ContentStream content,
                          int bufferSize,
                          SerializableStreamContentHandler.ContentHandlers contentHandler)

ContentStream constructor. Supports the content-hash and content-length validation of the given ContentStream.

Parameters:

token - user token

content - content stream to wrap

bufferSize - size of buffer chunk

contentHandler - handles the writing of the content when serializing this stream

Method Detail

getActualCount

public long getActualCount()

Gets the actual count.

Returns:

the actual count

validate

public void validate()
              throws StreamVerificationException

Validates the stream. Validation takes place after the stream was read, so call this method after this stream was serialized to the RMI server.

Throws:

StreamVerificationException - if the expected hash or length was not matched.

persist

public long persist()
             throws IOException

Persists this SerializableStream if required.

Returns:

position of the element in the document's structure or -1 if nothing was persisted

Throws:

IOException - IO Exception when persisting

getVariables

public Map<String,String> getVariables()

Returns the variables belonging to the content element written by this stream.

Returns:

variables map or null if no variables were set

isClearContent

public boolean isClearContent()

Returns:

True if the included ContentStream has no InputStream.

getPosition

public int getPosition()

Returns:

position of element in structure
