If you think of a single dimension array as an simple numbered list, a two dimension array can be though of as a spreadsheet with numbered rows and columns. Miva Script provides flexible tools for creating even more complex data structures.

Miva Script arrays are fully multi-dimensional (up to the limits of the system). If a value is assigned to an index or member that did not previously exist, the entry will be created.

Attributes

  • INDEX: Required, declares  the index of the array in NAME that will receive the VALUE.

Only allowed between <MvASSIGNARRAY> and </MvASSIGNARRAY>.

Two Dimensional Array

An tabular representation the array declared below could look like this.

  Column 1 Column 2
Row 1 100 200
Row 2 300 400
 

Example:

<MvASSIGNARRAY NAME = "l.coordinates" VALUE = "{ 100 }">
               <MvDIMENSION INDEX = "1">
               <MvDIMENSION INDEX = "1">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME = "l.coordinates" VALUE = "{ 200 }">
               <MvDIMENSION INDEX = "1">
               <MvDIMENSION INDEX = "2">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME = "l.coordinates" VALUE = "{ 300 }">
               <MvDIMENSION INDEX = "2">
               <MvDIMENSION INDEX = "1">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME = "l.coordinates" VALUE = "{ 400 }">
               <MvDIMENSION INDEX = "2">
               <MvDIMENSION INDEX = "2">
</MvASSIGNARRAY>

<MvEVAL EXPR="{ l.coordinates[2][1] }"><br>

result: 300
