Method Details

merge

public void merge(PropertySet other)

Specified by:

merge in interface Mergable<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

set

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

Specified by:

set in interface MutablePropertyValueSource

set

public void set(PropertyValue propValue)

Specified by:

set in interface MutablePropertyValueSource

getCount

public int getCount()

Specified by:

getCount in interface Countable

remove

public void remove(Property<?> prop)

Specified by:

remove in interface MutablePropertyValueSource

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

contains

public boolean contains(Property<?> prop)

Specified by:

contains in interface PropertyValueSource

Returns:

True if the source contains a value for prop.

getProperties

public Collection<Property<?>> getProperties()

Specified by:

getProperties in interface PropertyValueSource

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.

getValues

public List<PropertyValue> getValues()

Description copied from interface: PropertyValueSource

Returns the opaque PropertyValue objects. This can be useful when you want to avoid the strict type checking of the value, and it's important to note that if the property is bound, the value will be a BoundValue. Be very careful about overriding, and make sure to maintain the methodology of using getProperties to iterate and get (or getOrDefault), to get the value, because those are all handled differently by BoundPropertySets, ExtendedPropertySets, etc.

Specified by:

getValues in interface PropertyValueSource

extend

public PropertySet extend(PropertySet parent)

Description copied from interface: Extendable

If called on a child, gets the extension with the given parent.

Specified by:

extend in interface Extendable<PropertySet>

Specified by:

extend in interface PropertySet

iterator

public Iterator<PropertyValue> iterator()

Specified by:

iterator in interface Iterable<PropertyValue>

getOrElse

public <T> T getOrElse(Property<T> prop,
 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:

prop - 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.

getExtension

public PropertySet getExtension()

Description copied from interface: Extendable

This returns an object that represents the value only for the most "local" level. That is, this is the difference between the inherited base and the current extension. Complex objects should ensure that trait is true for all aspects of the returned value.

Specified by:

getExtension in interface Extendable<PropertySet>

Specified by:

getExtension in interface PropertySet

forEach

public void forEach(Consumer<? super PropertyValue> action)

Specified by:

forEach in interface Iterable<PropertyValue>

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

spliterator

public Spliterator<PropertyValue> spliterator()

Specified by:

spliterator in interface Iterable<PropertyValue>
