Constructor Details

ChainingOutputProcessor

public ChainingOutputProcessor(OutputProcessor outputProcessor)

Method Details

createInputFeed

public InputFeed createInputFeed(LayoutProcess layoutProcess)
Specified by:
createInputFeed in interface OutputProcessor

createModelBuilder

public ModelBuilder createModelBuilder(LayoutProcess layoutProcess)
The model builder normalizes the input and builds the Display-Model. The DisplayModel enriches and normalizes the logical document model so that it is better suited for rendering.
Specified by:
createModelBuilder in interface OutputProcessor
Parameters:
layoutProcess - the layout process that governs all.
Returns:
the created model builder.

createNormalizer

public Normalizer createNormalizer(LayoutProcess layoutProcess)
Returns the content normalizer implementation for this OP. The content normalizer is responsible for resolving the styles and for initiating the display model building.
Specified by:
createNormalizer in interface OutputProcessor
Parameters:
layoutProcess - the layout process that governs all.
Returns:
the created content normalizer.

createRenderer

public Renderer createRenderer(LayoutProcess layoutProcess)
Specified by:
createRenderer in interface OutputProcessor

getConfiguration

public Configuration getConfiguration()
Specified by:
getConfiguration in interface OutputProcessor

getLogicalPage

public LogicalPageKey getLogicalPage(int page)
Specified by:
getLogicalPage in interface OutputProcessor

getLogicalPageCount

public int getLogicalPageCount()
Specified by:
getLogicalPageCount in interface OutputProcessor

getMetaData

public OutputProcessorMetaData getMetaData()
Specified by:
getMetaData in interface OutputProcessor

getPageCursor

public int getPageCursor()
Specified by:
getPageCursor in interface OutputProcessor

isContentGeneratable

public boolean isContentGeneratable()
This flag indicates, whether the output processor has collected enough information to start the content generation.
Specified by:
isContentGeneratable in interface OutputProcessor
Returns:

isGlobalStateComputed

public boolean isGlobalStateComputed()
This flag indicates, whether the global content has been computed. Global content consists of global counters (except the pages counter) and derived information like table of contents, the global directory of images or tables etc.

The global state must be computed before paginating can be attempted (if the output target is paginating at all).

Specified by:
isGlobalStateComputed in interface OutputProcessor
Returns:
true, if the global state has been computed, false otherwise.

isPaginationFinished

public boolean isPaginationFinished()
Checks, whether the 'processingFinished' event had been received at least once.
Specified by:
isPaginationFinished in interface OutputProcessor
Returns:

processContent

public void processContent(LogicalPageBox logicalPage)
Specified by:
processContent in interface OutputProcessor

processDocumentMetaData

public void processDocumentMetaData(DocumentContext documentContext)
Specified by:
processDocumentMetaData in interface OutputProcessor

processingFinished

public void processingFinished()
Notifies the output processor, that the processing has been finished and that the input-feed received the last event.
Specified by:
processingFinished in interface OutputProcessor

setPageCursor

public void setPageCursor(int cursor)
Specified by:
setPageCursor in interface OutputProcessor
