All Implemented Interfaces:

Direct Known Subclasses:

CreatePDFPage

public abstract class CreateGenericBinaryPage

extends CreatePage

This class, together with oracle.clex.process.CreateGenericTextPage, provides an open content type structure for the MVC Framework. All Create...Page processes should extend either this class or CreateGenericTextPage.

Subclasses need to implement:
1) The setContentType() method, returning a String that is the mime type of the end result the process is to display. For example, CreatePDFPage's setContentType() returns "application/pdf", the mime type for a PDF document.
2) The getBinaryInputStream() method, returning an InputStream that is the binary file as a stream. This stream is placed in the infotable for use later.

Constructor Detail

CreateGenericBinaryPage

public CreateGenericBinaryPage()

Method Detail

registerInfo

protected void registerInfo()

Register the information that the process is interested in and declare any of the results(BINARYSIZE,GENERICBINARYRESULT,CONTENTTYPE) that this Process will produce.

Overrides:

registerInfo in class CreatePage

setCreatePageResult

protected void setCreatePageResult(java.lang.String result)

Application Should not need to invoke this method

Overrides:

setCreatePageResult in class CreatePage

getContentType

protected abstract java.lang.String getContentType()

Subclasses should return their mime type, application/pdf" for example, in this method.

getBinaryInputStream

protected abstract java.io.InputStream getBinaryInputStream()

Subclasses need to return the binary file as an input stream in this method. (M. Blok: the return type should be BufferedInputStream instead of InputStream! Should be changed eventually.)

printPage

protected void printPage(java.io.PrintWriter out)

Overrides:

printPage in class CreatePage

getLength

protected int getLength()

GetLength returns the length of the input stream. Override this method if you make use of buffered input streams since the available method only returns the number of bytes that can be read from this input stream without blocking by the next caller of a method for this input stream, and not necessarily the actual input stream length.

preStart

protected void preStart()

Called at begining of CreatePage.start().

Overrides:

preStart in class CreatePage

postStart

protected void postStart()

Called at the end of CreatePage.start().

Overrides:

postStart in class CreatePage
