Lua:Class:Strings

{} Class

class Strings : Object

The Strings class represents a list of strings.

A Strings object inherits from Object. It is mostly an abstract base class and is commonly used by other objects that expose string-list behavior.

Inheritance

Class	Inherits From	Description
Strings	Object	A string-list object. Mostly used as an abstract base class.

Properties

Property	Type	Description
LineBreak	String	The character or characters to count as a line break.
Text	String	All strings in the list as one string.
Count	Integer	The number of strings in the list.
String[]	String	Array access to a specific string in the list.
Data[]	Integer	Array access to the data value of a specific string in the list.
[]	String	Alias for String[].

Methods

Method	Return Type	Description
clear()	void	Deletes all strings in the list.
add(string, data)	Integer	Adds a string to the list and optionally associates an integer data value with it. Returns the index of the added string.
addText(strings)	void	Adds multiple strings at once.
delete(index)	void	Deletes the string at the specified index.
getText()	String	Returns all strings as one large string.
setText(string)	void	Sets the strings of the object to the given text. The input can be multiline.
indexOf(string)	Integer	Returns the index of the specified string. Returns -1 if it is not found.
insert(index, string)	void	Inserts a string at the specified index and moves the following items down.
getCount()	Integer	Returns the number of strings in the list.
remove(string)	void	Removes the given string from the list.
loadFromFile(filename, ignoreencoding)	void	Loads the strings from a text file. If ignoreencoding is false, the file is loaded using the best encoding the loader can guess. The default for ignoreencoding is true.
saveToFile(filename)	void	Saves the strings to a text file.
getString(index)	String	Returns the string at the given index.
setString(index, string)	void	Replaces the string at the given index.
getData(index)	Integer	Returns the integer data value stored for the string at the given index.
setData(index, integer)	void	Sets the integer data value stored for the string at the given index.
beginUpdate()	void	Stops updates from triggering other events. This can prevent flashing while multiple changes are being made.
endUpdate()	void	Ends an update block started with beginUpdate().

Examples

 1 local strings = createStringList()
 2 
 3 strings.add("First")
 4 strings.add("Second")
 5 strings.add("Third")
 6 
 7 print("Count: " .. tostring(strings.Count))
 8 print("First item: " .. strings[0])
 9 
10 strings.destroy()

 1 local strings = createStringList()
 2 
 3 strings.add("Health", 100)
 4 strings.add("Mana", 50)
 5 
 6 print(strings.getString(0))
 7 print(strings.getData(0))
 8 
 9 strings.setData(0, 150)
10 
11 print(strings.Data[0])
12 
13 strings.destroy()

1 local strings = createStringList()
2 
3 strings.Text = [[First line
4 Second line
5 Third line]]
6 
7 print(strings.getText())
8 
9 strings.destroy()

 1 local strings = createStringList()
 2 
 3 strings.beginUpdate()
 4 
 5 for i = 1, 100 do
 6   strings.add("Item " .. tostring(i))
 7 end
 8 
 9 strings.endUpdate()
10 
11 print("Items added: " .. tostring(strings.Count))
12 
13 strings.destroy()

 1 local strings = createStringList()
 2 
 3 strings.add("Line 1")
 4 strings.add("Line 2")
 5 
 6 strings.saveToFile("C:\\\\Temp\\\\strings.txt")
 7 strings.clear()
 8 strings.loadFromFile("C:\\\\Temp\\\\strings.txt")
 9 
10 print(strings.Text)
11 
12 strings.destroy()

Notes

• Strings is mostly an abstract base class.
• Objects that expose string-list behavior may use this class or a descendant of it.
• Index-based access starts at 0.
• Use beginUpdate() and endUpdate() when making many changes at once.
• When using standalone string-list objects, destroy them when they are no longer needed.
