setDefaultResourceProperties

public static void setDefaultResourceProperties(javax.jcr.Node node,
                                                String mimeType,
                                                InputStream inputStream)
                                         throws javax.jcr.RepositoryException

Set the default 'hippo:resource' properties:

• jcr:mimeType
• jcr:data
• jcr:lastModified

Parameters:

node - the Node on which to set the properties

mimeType - the mime-type of the binary data (e.g. application/pdf, image/jpeg)

inputStream - the data stream. Once the properties have been set the input stream will be closed.

Throws:

javax.jcr.RepositoryException - exception thrown when one of the properties or values could not be set

setDefaultResourceProperties

public static void setDefaultResourceProperties(javax.jcr.Node node,
                                                String mimeType,
                                                InputStream inputStream,
                                                String filename)
                                         throws javax.jcr.RepositoryException

Set the default 'hippo:resource' properties:

• jcr:mimeType
• jcr:data
• jcr:lastModified
• hippo:filename

Parameters:

node - the Node on which to set the properties

mimeType - the mime-type of the binary data (e.g. application/pdf, image/jpeg)

inputStream - the data stream. Once the properties have been set the input stream will be closed.

Throws:

javax.jcr.RepositoryException - exception thrown when one of the properties or values could not be set

setDefaultResourceProperties

public static void setDefaultResourceProperties(javax.jcr.Node node,
                                                String mimeType,
                                                javax.jcr.Binary binary,
                                                String filename)
                                         throws javax.jcr.RepositoryException

Set the default 'hippo:resource' properties:

• jcr:mimeType
• jcr:data
• jcr:lastModified
• hippo:filename

Parameters:

node - the Node on which to set the properties

mimeType - the mime-type of the binary data (e.g. application/pdf, image/jpeg)

binary - the binary data.

filename - the name of the resource file, should not be null or "".

Throws:

javax.jcr.RepositoryException - exception thrown when one of the properties or values could not be set

handlePdfAndSetHippoTextProperty

public static void handlePdfAndSetHippoTextProperty(javax.jcr.Node node,
                                                    InputStream inputStream)

Handles the InputStream and extract text content from the PDF and sets it as a binary type property on the resource node. Once the property has been set the input stream will be closed.

Parameters:

node - the Node on which to set the '"hippo:text"' property

inputStream - data stream

getValueFactory

public static javax.jcr.ValueFactory getValueFactory(javax.jcr.Node node)
                                              throws javax.jcr.RepositoryException

Gets the ValueFactory from the Session

Parameters:

node - the Node from which to get the Session

Returns:

a ValueFactory
