Constructor Details

FixedIATimeRV

public FixedIATimeRV(long value)
              throws IllegalArgumentException

Constructor.

Parameters:

value - the value of the random variable

Throws:

IllegalArgumentException

Method Details

getValue

public long getValue()

Get the value this random variable always produces.

Returns:

the value

setMinimum

public void setMinimum(Long min,
 boolean closed)
                throws UnsupportedOperationException,
IllegalArgumentException

Description copied from class: RandomVariable

Set the minimum value for a random variable.

Specified by:

setMinimum in interface RandomVariableOps<Long>

Overrides:

setMinimum in class LongRandomVariable

Parameters:

min - minimum value.

closed - true if the minimum value is part of the range; false if it is a lower bound on the range

Throws:

UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons

IllegalArgumentException - an argument is out of range

setMaximum

public void setMaximum(Long max,
 boolean closed)
                throws UnsupportedOperationException,
IllegalArgumentException

Description copied from class: RandomVariable

Set the maximum value for a random variable.

Specified by:

setMaximum in interface RandomVariableOps<Long>

Overrides:

setMaximum in class LongRandomVariable

Parameters:

max - maximum value.

closed - true if the minimum value is part of the range; false if it is a lower bound on the range

Throws:

UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons

IllegalArgumentException - an argument is out of range

next

public Long next()

Description copied from class: RandomVariable

Get the next value for a random variable. In general, each value will be independent of the last.

Specified by:

next in interface RandomVariableOps<Long>

Specified by:

next in class RandomVariable<Long>

Returns:

the next value

toString

public String toString()

Overrides:

toString in class Object
