Field Detail

projectFile

protected java.io.File projectFile

The domain file used for this configuration

Constructor Detail

FileConfiguration

public FileConfiguration()

Default constructor. Simply calls FileConfiguration(String) with Configuration.DEFAULT_DOMAIN_FILE as argument.

See Also:

DefaultConfiguration.DefaultConfiguration()

FileConfiguration

public FileConfiguration(java.lang.String domainConfigurationName)

Creates a configuration that uses the provided file name as the main project file, ignoring any other lookup strategies. The file name is not checked for existence and must not contain relative or absolute paths, i.e. only the file name.

Throws:

ConfigurationException - when projectFile is null.

See Also:

DefaultConfiguration.DefaultConfiguration(String)

FileConfiguration

public FileConfiguration(java.io.File domainConfigurationFile)

Creates a configuration that uses the provided file as the main project file, ignoring any other lookup strategies.

Throws:

ConfigurationException - when projectFile is null, a directory or not readable.

Method Detail

addFilesystemPath

public void addFilesystemPath(java.lang.String path)

Adds the given String as a custom path for filesystem lookups. The path can be relative or absolute and is not checked for existence. This allows for easy customization of resource search paths after Constructor invocation:

 conf = new FileConfiguration("myconfig-cayenne.xml");
 conf.addFilesystemPath(new File("a/relative/path"));
 conf.addFilesystemPath(new File("/an/absolute/search/path"));
 Configuration.initializeSharedConfiguration(conf);
 

Alternatively use addFilesystemPath(File) for adding a path that is checked for existence.

Throws:

java.lang.IllegalArgumentException - if path is null.

addFilesystemPath

public void addFilesystemPath(java.io.File path)

Adds the given directory as a path for filesystem lookups. The directory is checked for existence.

Throws:

java.lang.IllegalArgumentException - if path is null, not a directory or not readable.

canInitialize

public boolean canInitialize()

Only returns true when getProjectFile() does not return null.

Overrides:

canInitialize in class DefaultConfiguration

getProjectFile

public java.io.File getProjectFile()

Returns the main domain file used for this configuration.

setProjectFile

protected void setProjectFile(java.io.File projectFile)

Sets the main domain file used for this configuration.

Throws:

ConfigurationException - if projectFile is null, a directory or not readable.

getProjectDirectory

public java.io.File getProjectDirectory()

Returns the directory of the current project file as returned by getProjectFile().
