Vec Module (Dynamic Array)

The Vec module in Flow-Wing provides a vector (dynamic array) implementation for storing and manipulating collections of elements of a specific type. It supports common operations such as adding, getting, setting, and removing elements, as well as checking the size of the vector.

Key Features of the Vec Module Dynamic Arrays: Vectors can dynamically grow as new elements are added. Type-Specific Vectors: The module provides specialized vectors for different types such as Int, Bool, String, and Deci (decimal values).

Memory Management: The free() function is used to release memory allocated for the vector, ensuring efficient memory usage.

Supported Types in Vec Module

  • Vec::Int: A vector that stores integer values.
  • Vec::Bool: A vector that stores boolean values (true or false).
  • Vec::String: A vector that stores string values.
  • Vec::Deci: A vector that stores decimal values (floating-point numbers).

Importing Vec

bring Vec​

Working with integer vectors​

var intVec: Vec::Int = new Vec::Int()
intVec.add(10)
intVec.add(20)
print(intVec.get(0))
print(intVec.size()) 

intVec.remove(1)
print(intVec.size())
intVec.free()

Boolean vectors​

var boolVec: Vec::Bool = new Vec::Bool()
boolVec.add(true)
boolVec.add(false)
print(boolVec.get(0))
print(boolVec.size()) 

boolVec.remove(1)
print(boolVec.size()) 
boolVec.free()

String vectors​

var strVec: Vec::String = new Vec::String()
strVec.add("Hello")
strVec.add("World")
print(strVec.get(0)) 
print(strVec.size()) 

strVec.remove(1)
print(strVec.size()) 
strVec.free()

Decimal vectors​

var dblVec: Vec::Deci = new Vec::Deci()
dblVec.add(1.23)
dblVec.add(4.56)
print(dblVec.get(0)) 

dblVec.set(0, 6.78)
print(dblVec.get(0)) 
print(dblVec.size()) 

dblVec.remove(1)
print(dblVec.size()) 
dblVec.free()
