Mapper types

Canvas mapper working with custom Canvas types created and based on native JavaScript types behavior.

Mapper has tree kind of types:

• ReturnType - type that mapper node returns. Has the following types:

Type	Description	Example
String	Type that represents the string value.	"Some test string value"
Number	Type that represents the number value.	1 or 10 or -15
Boolean	Type that represents the boolean value.	true or false
Object	Type that represents the model of some abstract object.	json<br/>{ <br/> id: 1, <br/> name: "Car", <br/> description: "Car that can fly" <br/>}
Array	Type that represents the array of Objects	json<br/>[<br/> {<br/> id: 1,<br/> name: "Car",<br/> description: "Car that can fly"<br/> },<br/> {<br/> id: 2,<br/> name: "Plane",<br/> description: "Just a plane"<br/> }<br/>]
ArrayString	Type that represents the array of Strings	["Value 1", "Value 2", "Value 3"]
ArrayNumber	Type that represents the array of Numbers	[1, 2, 3]
ArrayBoolean	Type that represents the array of Booleans	[true, false, true]
Any	Type that represents any of possible types that can be existed in system.	true or 1 or "Value" or { id: 0 } or [1, 2, 3] etc.
Void	Type that represents nothing.	You can find it in Functions that do some changes without any output values.

• NodeType - type of mapper node. Has the following types:

Type	Description	Example
Property	General model field.	[string] description
Constant	Value that not change through mapping process.	[string] testConstant = "Test Value"
FixedValue	Fixed value that not exist in model and shows only value without any key or position in the tree.	You can find it only through manual texting in input.
Function	Function\Method. The same with JavaScript function.	[string] concat(testStringArray, ",")
AsyncFunction	The same with Function but with asynchronous processing.	[array] filter(testArray, predicate)
FunctionAssembledArray	Function assembled array exist only for function argument grouping.	You can find it only through manual texting in simple array inputs.

• ArgumentType - type of mapper functions. Has the following types:

Type	Description	Example
Predicate	Type that represents predicate (some condition) value.	item.id == 0
FieldName	Type that represents argument value as a reference to node.	testConstant as a name of node that exist in source tree.
