getBasePath

public java.lang.String getBasePath()

Description copied from interface: FileConfiguration

Returns the base path. One way to specify the location of a configuration source is by setting its base path and its file name. This method returns this base path. The concrete value returned by this method depends on the way the location of the configuration file was set. If methods like setFile() or setURL() were used, the base path typically points to the parent directory of the configuration file (e.g. for the URL file:/temp/test.properties the base path will be file:/temp/). If the base path was explicitly set using setBasePath(), this method will return the exact value specified here without further modifications.

Returns:

the base path

See Also:

AbstractFileConfiguration.setBasePath(String)

setBasePath

public void setBasePath(java.lang.String basePath)

Description copied from interface: FileConfiguration

Sets the base path. The methods setBasePath() and setFileName() can be used together to specify the location of the configuration file to be loaded. If relative file names are to be resolved (e.g. for the include files supported by PropertiesConfiguration), this base path will be used.

Specified by:

setBasePath in interface FileConfiguration

Throws:

ConfigurationException - if an error occurs

Since:

1.7

getReloadLock in interface Reloadable

Overrides:

getReloadLock in class HierarchicalConfiguration

Returns:

Specified by:

containsKey in interface Configuration

Overrides:

containsKey in class HierarchicalConfiguration

Parameters:

Returns:

a flag if this key is contained in this configuration

getKeys

public java.util.Iterator<java.lang.String> getKeys()

getKeys in interface Configuration

Overrides:

getKeys in class HierarchicalConfiguration

Returns:

an iterator with the defined keys in this configuration

getKeys

public java.util.Iterator<java.lang.String> getKeys(java.lang.String prefix)

Description copied from class: HierarchicalConfiguration

Returns an iterator with all keys defined in this configuration that start with the given prefix. The returned keys will not contain any indices. This implementation tries to locate a node whose key is the same as the passed in prefix. Then the subtree of this node is traversed, and the keys of all nodes encountered (including attributes) are added to the result set.

Specified by:

getKeys in interface Configuration

Overrides:

getKeys in class HierarchicalConfiguration

Parameters:

prefix - the prefix of the keys to start with

Returns:

an iterator with the found keys

See Also:

Specified by:

isEmpty in interface Configuration

Overrides:

isEmpty in class HierarchicalConfiguration

Returns:

a flag if this configuration is empty

addNodes

public void addNodes(java.lang.String key,
                     java.util.Collection<? extends ConfigurationNode> nodes)
