public interface Structure

Structure represents a potentially nested object type which is used to represent structured data.

Method Summary

Modifier and Type	Method and Description
Map<String,Value>	asMap() Get all values, as a map of Values.
Map<String,Object>	asObjectMap() Get all values, with as a map of Object.
default Object	convertValue(Value value) Converts the Value into its equivalent primitive type.
Value	getValue(String key) Get the value indexed by key.
Set<String>	keySet() Get all keys.
static Structure	mapToStructure(Map<String,Object> map) Transform an object map to a Structure type.
default <T extends Structure> Map<String,Value>	merge(Function<Map<String,Value>,Structure> newStructure, Map<String,Value> base, Map<String,Value> overriding) Recursively merges the base map with the overriding map.

Method Detail

keySet

Set<String> keySet()

Get all keys.

Returns:

the set of keys

getValue

Value getValue(String key)

Get the value indexed by key.

Parameters:

key - String the key.

Returns:

the Value

asMap

Map<String,Value> asMap()

Get all values, as a map of Values.

Returns:

all attributes on the structure into a Map

asObjectMap

Map<String,Object> asObjectMap()

Get all values, with as a map of Object.

Returns:

all attributes on the structure into a Map

convertValue

default Object convertValue(Value value)

Converts the Value into its equivalent primitive type.

Parameters:

value - - Value object to convert

Returns:

an Object containing the primitive type, or null.

merge

default <T extends Structure> Map<String,Value> merge(Function<Map<String,Value>,Structure> newStructure,
                                                      Map<String,Value> base,
                                                      Map<String,Value> overriding)

Recursively merges the base map with the overriding map.

Type Parameters:

T - Structure type

Parameters:

newStructure - function to create the right structure

base - base map to merge

overriding - overriding map to merge

Returns:

resulting merged map

mapToStructure

static Structure mapToStructure(Map<String,Object> map)

Transform an object map to a Structure type.

Parameters:

map - map of objects

Returns:

a Structure object in the SDK format
