GridMetaData Class Reference

This is a convenient class that allows for access to grid meta-data that are independent of the value type of a grid. That is, this class can be used to get information about a grid without actually knowing its ValueType. More...

Detailed Description

This is a convenient class that allows for access to grid meta-data that are independent of the value type of a grid. That is, this class can be used to get information about a grid without actually knowing its ValueType.
