Method Detail

close

public void close()

Description copied from interface: IFilter

Closes the input document. Developers should call this method from within their code before sending the last event: This can allow writer objects to overwrite the input file when they receive the last event. This method must also be safe to call even if the input document is not opened.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface IFilter

Overrides:

close in class AbstractFilter

hasNext

public boolean hasNext()

Description copied from interface: IFilter

Indicates if there is an event to process.

Implementer Note: The caller must be able to call this method several times without changing state.

Specified by:

hasNext in interface Iterator<Event>

Specified by:

hasNext in interface IFilter

Returns:

True if there is at least one event to process, false if not.

next

public Event next()

Description copied from interface: IFilter

Gets the next event available. Calling this method can be done only once on each event.

Specified by:

next in interface Iterator<Event>

Specified by:

next in interface IFilter

Returns:

The next event available or null if there are no events.

open

public void open(RawDocument input)

Description copied from interface: IFilter

Opens the input document described in a give RawDocument object. Skeleton information is always created when you use this method.

Specified by:

open in interface IFilter

Parameters:

input - The RawDocument object to use to open the document.

open

public void open(RawDocument input,
                 boolean generateSkeleton)

Description copied from interface: IFilter

Opens the input document described in a give RawDocument object, and optionally creates skeleton information.

Specified by:

open in interface IFilter

Overrides:

open in class AbstractFilter

Parameters:

input - The RawDocument object to use to open the document.

generateSkeleton - true to generate the skeleton data, false otherwise.

getParameters

public Parameters getParameters()

Description copied from interface: IFilter

Gets the current parameters for this filter.

Specified by:

getParameters in interface IFilter

Overrides:

Returns:

the EncoderManager for this filter.

createSkeletonWriter
