Specified by:

process in interface TextAssembler

Parameters:

unassembled - chunk of text rendering instruction to contribute to final text

process

public void process(FinalText completed,
                    String contextName)

Slot fully-assembled chunk into our result at the current location. If there are unassembled chunks waiting, assemble them first.

Specified by:

process in interface TextAssembler

Parameters:

completed - This is a chunk from a nested element

contextName - Name of the element context we are in. Null value if it's an Artifact.

process

public void process(Word completed,
                    String contextName)

Specified by:

process in interface TextAssembler

Parameters:

completed - process a complete chunk -- just add this subsection into the proper place.

contextName - Name of the element context we are in. Null value if it's an Artifact.

endParsingContext

public FinalText endParsingContext(String containingElementName)

Specified by:

endParsingContext in interface TextAssembler

Parameters:

containingElementName - This is an element name to surround the extracted text

Returns:

the final text for the set of fragments and fully parsed items we were passed during processing.

reset

public void reset()

Specified by:

reset in interface TextAssembler

renderText

public void renderText(FinalText finalText)

Specified by:

renderText in interface TextAssembler

Parameters:

finalText - process a complete chunk -- just add this subsection into the proper place.

renderText

public void renderText(ParsedTextImpl partialWord)

Captures text using a simplified algorithm for inserting hard returns and spaces

Specified by:

renderText in interface TextAssembler

Parameters:

partialWord - process one of a number of raw pdf text chunks, with placement, font, etc.

getReader

protected PdfReader getReader()

Returns:

reader

setPage

public void setPage(int page)

Specified by:
