The numeric value corresponding to the string specification.

floatValue

protected abstract float floatValue(String spec)

Returns the numeric value corresponding to a floating-point string specification.

Parameters:

spec - A floating-point string specification.

Returns:

The numeric value corresponding to the string specification.

visadSet

protected Set visadSet(List list)
                throws VisADException

Returns the VisAD Set corresponding to the metadata of the attribute used in constructing this instance and a list of numeric values.

Specified by:

visadSet in class NumericAttributeAdapter

Parameters:

list - A list of numeric values. Each element must be of class Float.
