Method Detail

sanitizeMimeType

public static String sanitizeMimeType(String mimeType)

Mimetypes can be a tricky thing as browsers and/or environments tend to alter them without good reason. This method will try to fix any of the quirks concerning mimetypes that are found out there.

Parameters:

mimeType - The mimetype that needs to be sanitized.

Returns:

A standard compliant mimetype in lowercase

validateResource

public static void validateResource(javax.jcr.Node resource,
                    String filename)
                             throws ResourceException,
                                    javax.jcr.RepositoryException

Throws:

ResourceException

javax.jcr.RepositoryException

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)
