Specified by:

toFile in interface ConfigFileLoaderPlugin

Parameters:

fileUri - the uri to use to resolve to a file (or not).

getUriScheme

public String getUriScheme()

Description copied from interface: ConfigFileLoaderPlugin

Returns the URI scheme that this loader supports.

Specified by:

getUriScheme in interface ConfigFileLoaderPlugin

getSupportedUriSchemes

public Set<String> getSupportedUriSchemes()

Return all URI schemes that are supported in the system.

lastModified

public Optional<Long> lastModified(URI fileURI)

Description copied from interface: ConfigFileLoaderPlugin

return the last modified time of the file URI.

Specified by:

lastModified in interface ConfigFileLoaderPlugin

Parameters:

fileURI - the uri of the config file to load.

Returns:

return the last modified date of the file

isAccessible

public boolean isAccessible(URI fileURI)

Description copied from interface: ConfigFileLoaderPlugin

Check if the configuration File exists.

Specified by:

isAccessible in interface ConfigFileLoaderPlugin

Parameters:

fileURI - the uri of the file to load.

loadFile

public byte[] loadFile(URI fileURI)
                throws IOException

Description copied from interface: ConfigFileLoaderPlugin

Load the config data.

Specified by:

loadFile in interface ConfigFileLoaderPlugin

Parameters:

fileURI - the uri of the config file to load.

Returns:

the file that make up the file.

Throws:

IOException

isAccessible

public boolean isAccessible(URI configFileUri,
 String pathToSubResource)
                     throws IOException

Description copied from interface: ConfigFileLoaderPlugin

check if the file exists and can be accessed by the user/template/config/etc...

Specified by:

isAccessible in interface ConfigFileLoaderPlugin

Parameters:

configFileUri - the uri of the configuration file

pathToSubResource - a string representing a file that is accessible for use in printing templates within the configuration file. In the case of a file based URI the path could be a relative path (relative to the configuration file) or an absolute path, but it must be an allowed file (you can't allow access to any file on the file system).

Throws:

IOException
