Field Detail

properties

protected final T extends Hashtable properties

The Hashtable instance which stores the property name-value associations of this ConfigurationStore instance and which is effectively adapted by this instance to ConfigurationStore.

Constructor Detail

HashtableConfigurationStore

protected HashtableConfigurationStore(T properties)

Creates an instance of this class using properties as the set of properties where it will be storing an retrieving properties.

Parameters:

properties - the map that this store will use for storing and retrieving properties.

Method Detail

getProperty

public Object getProperty(String name)

Implements ConfigurationStore.getProperty(String). If this ConfigurationStore contains a value associated with the specified property name, returns it. Otherwise, searches for a system property with the specified name and returns its value.

Specified by:

getProperty in interface ConfigurationStore

Parameters:

name - the name of the property to get the value of

Returns:

the value in this ConfigurationStore of the property with the specified name; null if the property with the specified name does not have an association with a value in this ConfigurationStore

See Also:

ConfigurationStore.getProperty(String)

getPropertyNames

public String[] getPropertyNames()

Implements ConfigurationStore.getPropertyNames(). Gets the names of the properties which have values associated in this ConfigurationStore.

Specified by:

getPropertyNames in interface ConfigurationStore

Returns:

an array of Strings which specify the names of the properties that have values associated in this ConfigurationStore; an empty array if this instance contains no property values

See Also:

ConfigurationStore.getPropertyNames()

isSystemProperty

public boolean isSystemProperty(String name)

Implements ConfigurationStore.isSystemProperty(String). Considers a property to be system if the system properties contain a value associated with its name.

Specified by:

isSystemProperty in interface ConfigurationStore

Parameters:

name - the name of a property which is to be determined whether it is a system property

Returns:

true if the specified name stands for a system property; false, otherwise

See Also:

ConfigurationStore.isSystemProperty(String)

removeProperty

public void removeProperty(String name)

Implements ConfigurationStore.removeProperty(String). Removes the value association in this ConfigurationStore of the property with a specific name. If the property with the specified name is not associated with a value in this ConfigurationStore, does nothing.

Specified by:

removeProperty in interface ConfigurationStore

Parameters:

name - the name of the property which is to have its value association in this ConfigurationStore removed

See Also:

ConfigurationStore.removeProperty(String)

setNonSystemProperty

public void setNonSystemProperty(String name,
                                 Object value)

Implements ConfigurationStore.setNonSystemProperty(String, Object).

Specified by:

setNonSystemProperty in interface ConfigurationStore

Parameters:

name - the name of the non-system property to be set to the specified value in this ConfigurationStore

value - the value to be assigned to the non-system property with the specified name in this ConfigurationStore

See Also:

ConfigurationStore.setNonSystemProperty(String, Object)

setSystemProperty

public void setSystemProperty(String name)

Implements ConfigurationStore.setSystemProperty(String). Since system properties are managed through the System class, setting a property as system in this ConfigurationStore effectively removes any existing value associated with the specified property name from this instance.

Specified by:

setSystemProperty in interface ConfigurationStore

Parameters:

name - the name of the property to be set as a system property in this ConfigurationStore

ConfigurationStore.setSystemProperty(String)
