void |
eventOccurred(IEventData data, EventType type)
Called when some event occurs during parsing a content stream.
|
String |
getResultantText()
Returns the text that has been processed so far.
|
Set<EventType> |
getSupportedEvents()
Provides the set of event types this listener supports.
|
protected boolean |
isChunkAtWordBoundary(LocationTextExtractionStrategy.TextChunk chunk, LocationTextExtractionStrategy.TextChunk previousChunk)
Determines if a space character should be inserted between a previous chunk and the current chunk.
|
boolean |
isUseActualText()
Gets the value of the property which determines if /ActualText will be used when extracting the text
|
LocationTextExtractionStrategy |
setRightToLeftRunDirection(boolean rightToLeftRunDirection)
Sets if text flows from left to right or from right to left.
|
LocationTextExtractionStrategy |
setUseActualText(boolean useActualText)
Changes the behavior of text extraction so that if the parameter is set to true , /ActualText marked content property will be used instead of raw decoded bytes.
