getNewFileName

java.lang.String getNewFileName(CmsObject cms,
                                java.lang.String namePattern,
                                int defaultDigits)
                                throws CmsException

namePattern - the pattern to be used when generating the new resource name

defaultDigits - the default number of digits to use for numbering the created file names

Returns:

a new resource name based on the provided OpenCms user context and name pattern

Throws:

CmsException - in case something goes wrong

getUniqueFileName

java.lang.String getUniqueFileName(CmsObject cms,
                                   java.lang.String parentFolder,
                                   java.lang.String baseName)

Returns a unique filename for the given base name and the parent folder.

Parameters:

cms - the current OpenCms user context

parentFolder - the parent folder of the file

baseName - the proposed file name

getUrlNameSequence

java.util.Iterator<java.lang.String> getUrlNameSequence(java.lang.String baseName)
                                                        throws CmsException

Usually the first URL name from this sequence which does not already exist for a different resource will be used for the URL name mapping.

Parameters:

baseName - the base name

Returns:

the sequence of URL name candidates

Throws:

CmsException - if something goes wrong
