NamedPointCollection

A collection of named points in the model.

Example

application = cf.Application.GetInstance()
project = application:NewProject()

    -- Create various named points

project.Definitions.NamedPoints:Add("pt1", 1.2, 1.4, 0.6)
project.Definitions.NamedPoints:Add("pt2", 0.2, 2.4, 0.1)
project.Definitions.NamedPoints:Add("pt3", -1.2, 2.5, 1.0)

    -- Set the Z value of "pt1" for all the named points

for key,point in pairs(project.Definitions.NamedPoints) do
    point.Point.N = project.Definitions.NamedPoints["pt1"].Point.N
end

Inheritance

The NamedPointCollection object is derived from the Object object.

Usage locations

The NamedPointCollection object can be accessed from the following locations:

Property List

Count
The number of NamedPoint items in the collection. (Read only number)
Label
The object label. (Read/Write string)
Type
The object type string. (Read only string)

Method List

Add (name string, x Expression, y Expression, z Expression)
Create a named point from the given coordinate expressions. (Returns a NamedPoint object.)
Contains (label string)
Checks if the collection contains an item with the given label. (Returns a boolean object.)
Delete ()
Deletes the entity.
Duplicate ()
Duplicates the entity. (Returns a Object object.)
GetProperties ()
Returns a table of properties representing the state of the object. The properties table can be used with the SetProperties method to change multiple properties of the object in one step. (Returns a table object.)
Item (index number)
Returns the NamedPoint for the given index in the collection. (Returns a NamedPoint object.)
Item (label string)
Returns the NamedPoint for the given label in the collection. (Returns a NamedPoint object.)
Items ()
Returns a table of NamedPoint items. (Returns a UnsupportedType(List of NamedPoint) object.)
SetProperties (properties Object)
Modifies the state of the object using the provided table of properties. This method is used to modify multiple properties of the object in a single step.
UniqueName (label string)
Generates a unique name base of the provided base name. If the base name already exists in the collection, a digit will be appended until a valid name is generated. (Returns a string object.)

Static Function List

GetDefaultProperties ()
Creates a table containing the default settings to create an object. (Returns a table object.)

Method Details

Add (name string, x Expression, y Expression, z Expression)
Create a named point from the given coordinate expressions.
Input Parameters
name(string)
The point name.
x(Expression)
The X coordinate expression.
y(Expression)
The Y coordinate expression.
z(Expression)
The Z coordinate expression.
Return
NamedPoint
The named point.
Contains (label string)
Checks if the collection contains an item with the given label.
Input Parameters
label(string)
The label of the item.
Return
boolean
The success of the check.
Delete ()
Deletes the entity.
Duplicate ()
Duplicates the entity.
Return
Object
The new (duplicated) entity.
GetProperties ()
Returns a table of properties representing the state of the object. The properties table can be used with the SetProperties method to change multiple properties of the object in one step.
Return
table
A table defining the properties.
Item (index number)
Returns the NamedPoint for the given index in the collection.
Input Parameters
index(number)
The index of the NamedPoint.
Return
NamedPoint
The item in the collection
Item (label string)
Returns the NamedPoint for the given label in the collection.
Input Parameters
label(string)
The label of the NamedPoint.
Return
NamedPoint
The item in the collection
Items ()
Returns a table of NamedPoint items.
Return
UnsupportedType(List of NamedPoint)
The list of items in the collection
SetProperties (properties Object)
Modifies the state of the object using the provided table of properties. This method is used to modify multiple properties of the object in a single step.
Input Parameters
properties(Object)
A table of properties defining the new state of the object.
UniqueName (label string)
Generates a unique name base of the provided base name. If the base name already exists in the collection, a digit will be appended until a valid name is generated.
Input Parameters
label(string)
The base name.
Return
string
The generated unique name label for the item.
