Method Detail

getCollectionValue

public double[] getCollectionValue(java.util.Collection c)

getDouble

public double getDouble()

Invoke the method of the object passed to constructor and return its double result.

Returns:

The requested double value.

getDouble

public double getDouble(java.lang.Object target)

Invoke the method of the target object and return its double result.

Parameters:

target - Object to be invoked.

Returns:

The requested double value.

getDoubleValue

This is an implementation of the IDblSource interface. It calls the getDouble() method.

Specified by:

getDoubleValue in interface IDoubleSource

Parameters:

valueID - This parameter is ignored. It is put for compatibility with the IDblSource interface.

Returns:

The requested double value.
