Field Detail

applet

protected java.applet.Applet applet

Stores the wrapped applet.

Constructor Detail

AppletConfiguration

public AppletConfiguration(java.applet.Applet applet)

Create an AppletConfiguration using the initialization parameters of the specified Applet.

Parameters:

applet - the applet

Method Detail

getPropertyInternal

protected java.lang.Object getPropertyInternal(java.lang.String key)

Description copied from class: AbstractConfiguration

Actually obtains the value of the specified property. This method is called by getProperty(). Concrete subclasses must define it to fetch the value of the desired property.

Specified by:

getPropertyInternal in class AbstractConfiguration

Parameters:

key - the key of the property in question

Returns:

the (raw) value of this property

getKeysInternal

protected java.util.Iterator<java.lang.String> getKeysInternal()

Description copied from class: AbstractConfiguration

Actually creates an iterator for iterating over the keys in this configuration. This method is called by getKeys(), it has to be defined by concrete subclasses.

Specified by:

getKeysInternal in class AbstractConfiguration

Returns:

an Iterator with all property keys in this configuration

isEmptyInternal

protected boolean isEmptyInternal()

Checks if this configuration is empty. This implementation makes use of the getKeys() method (which must be defined by concrete sub classes) to find out whether properties exist.

Specified by:

isEmptyInternal in class AbstractConfiguration

Returns:

a flag whether this configuration is empty

containsKeyInternal

protected boolean containsKeyInternal(java.lang.String key)

Checks whether the specified key is stored in this configuration.

Specified by:

containsKeyInternal in class AbstractConfiguration

Parameters:

key - the key

Returns:

a flag whether this key exists in this configuration

clearPropertyDirect

protected void clearPropertyDirect(java.lang.String key)

Removes the property with the given key. This operation is not supported and will throw an UnsupportedOperationException.

Specified by:

clearPropertyDirect in class AbstractConfiguration

Parameters:

key - the key of the property to be removed

Throws:

java.lang.UnsupportedOperationException - because this operation is not allowed

addPropertyDirect

protected void addPropertyDirect(java.lang.String key,
                                 java.lang.Object obj)

Adds a property to this configuration. This operation is not supported and will throw an UnsupportedOperationException.

Specified by:

addPropertyDirect in class AbstractConfiguration

Parameters:

key - the key of the property

obj - the value to be added

Throws:

java.lang.UnsupportedOperationException - because this operation is not allowed

handleDelimiters

protected java.lang.Object handleDelimiters(java.lang.Object value)

Takes care of list delimiters in property values. This method checks if delimiter parsing is enabled and the passed in value contains a delimiter character. If this is the case, a split operation is performed.

Parameters:

value - the property value to be examined

Returns:

the processed value
