Package com.inductiveautomation.ignition.common.config

Class CompositePropertySet

java.lang.Object

com.inductiveautomation.ignition.common.config.CompositePropertySet

All Implemented Interfaces:

Countable, Extendable<PropertySet>, Mergable<PropertySet>, MutablePropertyValueSource, PropertySet, PropertyValueSource, java.io.Serializable, java.lang.Iterable<PropertyValue>

public class CompositePropertySet
extends java.lang.Object
implements PropertySet

A composite property set holds multiple other property sets, and loops through them to find properties.

In regards to the property set interface, any adds or merges will be applied to a new internal propertyset. In other words, the operations will work as expected in regards to this object, but nothing will be transfered to the other property sets. However, removal operations will be applied to each wrapped propertyset.

Method Detail

getInternal

protected PropertySet getInternal()

iterator

public java.util.Iterator<PropertyValue> iterator()

Specified by:

iterator in interface java.lang.Iterable<PropertyValue>

contains

public boolean contains(Property<?> prop)

Specified by:

contains in interface PropertyValueSource

Returns:

True if the source contains a value for prop.

getOrDefault

public <T> T getOrDefault(Property<T> prop)

Specified by:

getOrDefault in interface PropertyValueSource

Returns:

The value for prop or Property.getDefaultValue() if not present. Can return null if the value is null.

getOrElse

public <T> T getOrElse(Property<T> property,
                       T value)

Description copied from interface: PropertyValueSource

Get the value for a given Property, or else fall back to value if it's not present.

Specified by:

getOrElse in interface PropertyValueSource

Parameters:

property - The Property for which a value is to be retrieved.

value - The value to default to if property isn't present.

Returns:

The value of property if present, value if not. Can return null if the value is null.

get

public <T> T get(Property<T> prop)

Description copied from interface: PropertyValueSource

Retrieves the value of the property, or null if this set doesn't contain that property.

Specified by:

get in interface PropertyValueSource

set

public <T> void set(Property<T> prop,
                    T value)

Specified by:

set in interface MutablePropertyValueSource

Specified by:

getValues in interface PropertyValueSource

isExtended

public boolean isExtended(Property<?> prop)

Description copied from interface: PropertySet

Returns whether this property set contains a value for the prop, and the prop was actually inherited. In other words, this is true if the property is inherited, and an override value is present.

Specified by:

isExtended in interface PropertySet

isInherited

public boolean isInherited(Property<?> prop)

Description copied from interface: PropertySet

Indicates whether the property was inherited from a parent type.

Specified by:

isInherited in interface PropertySet

merge

public void merge(PropertySet other,
                  boolean local)

Description copied from interface: Mergable

Merges the values from other collection into this one. Replaces any currently existing value with those from the other set.

Specified by:

merge in interface Mergable<PropertySet>

Specified by:

merge in interface MutablePropertyValueSource
