Method Details

asEntity

public V asEntity()

Description copied from interface: Value

Returns the value as a Entity, if possible.

Specified by:

asEntity in interface Value

Overrides:

asEntity in class ValueAdapter

Returns:

the value as a Entity, if possible

asMap

public Map<String,Object> asMap()

Description copied from interface: MapAccessor

Return the underlying map as a map of string keys and values converted using Value.asObject().

This is equivalent to calling MapAccessor.asMap(Function) with Values.ofObject().

Specified by:

asMap in interface MapAccessor

Overrides:

asMap in class ValueAdapter

Returns:

the value as a Java map

asMap

public <T> Map<String,T> asMap(Function<Value,T> mapFunction)

Description copied from interface: MapAccessor

Return the underlying map as a map of string keys and values converted using the supplied function.

Specified by:

asMap in interface MapAccessor

Overrides:

asMap in class ValueAdapter

Type Parameters:

T - the type of map values

Parameters:

mapFunction - a function to map from Value to T. See Values for some predefined functions, such as Values.ofBoolean(), Values.ofList(Function).

Returns:

the value as a map from string keys to values of type T obtained from mapping the original map values, if possible

• for a long list of built-in conversion functions

size

public int size()

Description copied from interface: MapAccessor

Retrieve the number of entries in this map

Specified by:

size in interface MapAccessor

Specified by:

size in interface Value

Overrides:

size in class ValueAdapter

Returns:

the number of entries in this map

keys

public Iterable<String> keys()

Description copied from interface: MapAccessor

Retrieve the keys of the underlying map

Specified by:

keys in interface MapAccessor

Specified by:

keys in interface Value

Overrides:

keys in class ValueAdapter

Returns:

all map keys in unspecified order

get

public Value get(String key)

Description copied from interface: MapAccessor

Retrieve the value of the property with the given key

Specified by:

get in interface MapAccessor

Overrides:

get in class ValueAdapter

Parameters:

key - the key of the property

Returns:

the property's value or a NullValue if no such key exists
