inline

Type safe method of retrieving value from a variable.

This function provides a type-safe interface for extracting values from the item class The variable type is automatically inferred from the passed type- For example, passing an int to recieve an unsigned will result in a failure, as will passing anything other than a size_t. Same goes for doubles and floats

When retrieving item* type classes, the type of pointer passed must be in the same inheritance line as the value being retrieved.

Parameters

inval	A reference to the variable that will recieve the internal value of the item
name	The name of the item being retrieved
caller	The item receiving the variable
