getFilePaths

public String[] getFilePaths(boolean showSamples)

Specified by:

getFilePaths in class BaseFileMeta

Parameters:

showSamples - determines whether the paths being returned are dummy samples or the "template" representation. The samples woulc include things like sample step number, partition number etc ( filename_0_1.txt) , while the non-sample path would include a token ( filename_<step>_<partition>.<extension>)

Returns:

An array of file paths
