Method Detail

getInstance

public static ExtractionService getInstance()

canHandle

public boolean canHandle(JCRNodeWrapper node)
                  throws IOException

Performs a check if the provided node can be handled by currently configured parsers.

Parameters:

node - the node to be checked

Returns:

true if there is a parser that can handle provided node's content

Throws:

IOException - in case of the read/write errors

extractProperties

public void extractProperties(AddedNodeFact node,
                              org.drools.core.spi.KnowledgeHelper drools)
                       throws Exception

Extract properties from document

Parameters:

node - file node in JCR

drools - context of the rule engine

Throws:

Exception

extractText

public void extractText(JCRStoreProvider provider,
                        String sourcePath,
                        String extractionNodePath)
                 throws IOException

Synchronously extract text from document and store it as a property of either the file node itself or the node referred to by the extractionNodePath parameter. The node must have the following properties, which will be set: j:extractedText, j:lastExtractionDate and for the case of extractionNodePath being passed also j:originalUuid is required.

Parameters:

provider - the JCR store provider

sourcePath - the path to the file node

extractionNodePath - the optional path to the node receiving the extracted text

Throws:

IOException

extractText

public boolean extractText(JCRStoreProvider provider,
                           String sourcePath,
                           String extractionNodePath,
                           String workspace)
                    throws IOException

Synchronously extract text from document and store it as a property of either the file node itself or the node referred to by the extractionNodePath parameter. The node must have the following properties, which will be set: j:extractedText, j:lastExtractionDate and for the case of extractionNodePath being passed also j:originalUuid is required.

Parameters:

provider - the JCR store provider

sourcePath - the path to the file node

extractionNodePath - the optional path to the node receiving the extracted text

workspace - the workspace, where document was saved (default or live)

Throws:

IOException
