Method Detail

timestamp

long timestamp()

Returns the timestamp (in milliseconds) associated with this data point.

Returns:

A strictly positive, 32 bit integer.

isInteger

boolean isInteger()

Tells whether or not the this data point is a value of integer type.

Returns:

true if the ith value is of integer type, false if it's of doubleing point type.

longValue

long longValue()

Returns the value of the this data point as a long.

Throws:

ClassCastException - if the isInteger() == false.

doubleValue

double doubleValue()

Returns the value of the this data point as a double.

Throws:

ClassCastException - if the isInteger() == true.

toDouble

double toDouble()

Returns the value of the this data point as a double, even if it's a long.

Returns:

When isInteger() == false, this method returns the same thing as doubleValue(). Otherwise, it returns the same thing as longValue()'s return value casted to a double.
