Method Detail

resolveFiles

protected abstract java.util.Iterator<java.io.File> resolveFiles(java.net.URI fileURI)

Load the files referenced by the id (in the case of a classpath uri it could references several files, although normally it will only reference one).

Parameters:

fileURI - the uri identifying the config file.

toFile

public final com.google.common.base.Optional<java.io.File> toFile(java.net.URI fileUri)

Description copied from interface: ConfigFileLoaderPlugin

Return the file object the uri refers to if it refers to a file. Otherwise Optional.absent().

Specified by:

toFile in interface ConfigFileLoaderPlugin

Parameters:

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

lastModified

public final com.google.common.base.Optional<java.lang.Long> lastModified(java.net.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 final boolean isAccessible(java.net.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 final byte[] loadFile(java.net.URI fileURI)
                      throws java.io.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:

java.io.IOException

isAccessible

public final boolean isAccessible(java.net.URI configFileUri,
                                  java.lang.String pathToSubResource)
                           throws java.io.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:

java.io.IOException

loadFile

public final byte[] loadFile(java.net.URI configFileUri,
                             java.lang.String pathToSubResource)
                      throws java.io.IOException

Description copied from interface: ConfigFileLoaderPlugin

Load the file related to the configuration file.

Specified by:

loadFile 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:

java.io.IOException

platformIndependentUriToFile

protected static java.io.File platformIndependentUriToFile(java.net.URI fileURI)

Convert a url to a file object. No checks are made to see if file exists but there are some hacks that are needed to convert uris to files across platforms.

Parameters:
