Method Detail

getMaxArgCount

public int getMaxArgCount()

Description copied from class: FunctionExpressionWithArgs

DERIVED CLASSES: The maximum number of arguments for a function. Defaults to one. Override if your function requires a different number of arguments (comma- or space-separated). Return -1 if your function accepts unlimited arguments.

Overrides:

getMaxArgCount in class FunctionExpressionWithArgs

getValueInternal

public double getValueInternal(int index,
                               java.util.Vector vArgs,
                               IDataSource dataSource,
                               ExpressionError error)

Description copied from class: FunctionExpressionWithArgs

DERIVED CLASSES: You must override this method to process the actual arguments to your function, and provide a result.

Specified by:

getValueInternal in class FunctionExpressionWithArgs

Parameters:

index - - Index number to use when getting data.

vArgs - - Vector of IExpression objects.

dataSource - - Can provide actual data values.

error - - Set this if you encounter an error.

Returns:

The actual function result.
