Method Detail

ofType

public static <T> SystemProperty.Builder<T> ofType(Class<T> clazz)

Start a new SystemProperty builder. The following types of SystemProperty are supported:

• String
• Integer - for which a default value must be supplied using setDefaultValue(Object)
• Long - for which a default value must be supplied
• Double - for which a default value must be supplied
• Boolean - for which a default value must be supplied
• Duration - for which a ChronoUnit must be specified, to indicate how the value will be saved, using setChronoUnit(ChronoUnit)
• Instant
• JID
• Class - for which a base class must be specified from which values must inherit, using setBaseClass(Class)
• any Enum - for which a default value must be supplied
• List - for which a collection type must be specified, using buildList(Class)
• Set - for which a collection type must be specified, using buildSet(Class)

Type Parameters:

T - the type of SystemProperty

Parameters:

clazz - The class of property being built

Returns:

A SystemProperty builder

setKey

public SystemProperty.Builder<T> setKey(String key)

Sets the key for the SystemProperty. Must be unique

Parameters:

key - the property key

Returns:

The current SystemProperty builder

setDefaultValue

public SystemProperty.Builder<T> setDefaultValue(T defaultValue)

Sets the default value for the SystemProperty. This value will be used if the property is not set, or falls outside the minimum/maximum values configured.

Parameters:

defaultValue - the default value for the property

Returns:

The current SystemProperty builder

See Also:

setMinValue(Object), setMaxValue(Object)

setBaseClass

public SystemProperty.Builder<T> setBaseClass(Class<?> baseClass)

This indicates which class configured values must inherit from. It must be set (and can only be set) if the default value is a class.

Parameters:

baseClass - - the base class from which all configured values must inherit

Returns:

The current SystemProperty builder

setMinValue

public SystemProperty.Builder<T> setMinValue(T minValue)

Sets the minimum value for the SystemProperty. If the configured value is less than minimum value, the default value will be used instead.

Important: If a minimum value is configured, the type of property being built must implement Comparable.

Parameters:

minValue - the minimum value for the property

Returns:

The current SystemProperty builder

setMaxValue

public SystemProperty.Builder<T> setMaxValue(T maxValue)

Sets the maximum value for the SystemProperty. If the configured value is more than maximum value, the default value will be used instead.

Important: If a maximum value is configured, the type of property being built must implement Comparable.

Parameters:

maxValue - the maximum value for the property

Returns:

The current SystemProperty builder

setChronoUnit

public SystemProperty.Builder<T> setChronoUnit(ChronoUnit chronoUnit)

If the type of the property is a Duration this is used to indicate how the value is saved in the database. For an example a Duration of one hour will be saved as "60" if the ChronoUnit is ChronoUnit.MINUTES, or saved as "3600" if the ChronoUnit is ChronoUnit.SECONDS.

Important: The ChronoUnit is required, and must be set, if the type of property is a Duration.

Parameters:

chronoUnit - the unit of time the Duration is saved to the database in

Returns:

The current SystemProperty builder

addListener

public SystemProperty.Builder<T> addListener(Consumer<T> listener)

Parameters:

listener - the listener that will be called when the value of the property changes

Returns:

The current SystemProperty builder

setDynamic

public SystemProperty.Builder<T> setDynamic(boolean dynamic)

Parameters:

dynamic - true if changes to this property take effect immediately, false if a restart is required.

Returns:

The current SystemProperty builder

setEncrypted

public SystemProperty.Builder<T> setEncrypted(boolean encrypted)

Parameters:

encrypted - true if this property should be encrypted, false if can be stored in plain text. Defaults to plain text if not otherwise specified.

Returns:

The current SystemProperty builder

setSorted

public SystemProperty.Builder<T> setSorted(boolean sorted)

Parameters:

sorted - true if this property is a list and should be sorted, false otherwise.

Returns:

The current SystemProperty builder

setPlugin

public SystemProperty.Builder<T> setPlugin(String plugin)

Sets the name of the plugin that is associated with this property. This is used on the Openfire System Properties admin interface to provide filtering capabilities. This will default to Openfire if not set.

Parameters:

plugin - the name of the plugin creating this property.

Returns:

The current SystemProperty builder

build

public SystemProperty<T> build()
                        throws IllegalArgumentException

Validates the details of the SystemProperty, and generates one if it's valid.

Returns:

A SystemProperty object

Throws:

IllegalArgumentException - if incorrect arguments have been supplied to the builder

buildList

public <C> SystemProperty<List<C>> buildList(Class<C> listType)

buildSet

public <C> SystemProperty<Set<C>> buildSet(Class<C> listType)
