Libraries.Interface.Controls.Charts.MapReader Documentation

This class is used to reads a csv that describes the map region boundaries. This reader also finds the min/max for the map. It stores the result in a text array of the region names, and a hashtable with an entry for each region. The delimiters can be set manually for the csv being read in. An example of the csv accepted with the default delimiters: e.g. ID,Name,Coordinates NV,Nevada,956 153|-3 -1;0 2;

Actions Documentation

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

GetMaxXValue()

Split()

Return

number:

GetMaxYValue()

should be size 2

Return

number:

GetMinXValue()

Split()

Return

number:

GetMinYValue()

parse coords

Return

number:

GetRegionNames()

end GetRegionTable()

Return

Libraries.Containers.Array:

GetRegionTable()

csv separator

Return

Libraries.Containers.HashTable:

Read(text filePath)

once this is called successfully, can GetRegionTable or GetRegionsArray

Parameters

  • text filePath
