Direct Known Subclasses:

BinomialBooleanRVRV, FixedBooleanRVRV

public abstract class BooleanRandomVariableRV<BRV extends BooleanRandomVariable>
extends RandomVariableRV<Boolean,BRV>

Random variable that generates the a sequence of random variables, each of which generates a sequence of boolean values (of type Boolean). The type parameter BRV is set to the type of random variable that is to be generated, which will usually be a subclass of LongRandomVariable.

BooleanRandomVariableRV

public BooleanRandomVariableRV()

Method Details

next

public abstract BRV 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<BRV extends BooleanRandomVariable>

Specified by:

next in class RandomVariable<BRV extends BooleanRandomVariable>

Returns:

the next value

tightenMinimumS

public void tightenMinimumS(String s,
 boolean closed)
                     throws UnsupportedOperationException

Description copied from class: RandomVariable

Tighten the minimum value for a random variable given a string. If there is no minimum value, it will be set. Otherwise the minimum of the allowed range will not decrease. The string argument is a number in a format acceptable to the constructors for Integer, Long, or Double as appropriate.

Specified by:

tightenMinimumS in interface RandomVariableOps<BRV extends BooleanRandomVariable>

Specified by:

tightenMinimumS in class RandomVariable<BRV extends BooleanRandomVariable>

Parameters:

s - 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

tightenMaximumS

public void tightenMaximumS(String s,
 boolean closed)
                     throws UnsupportedOperationException

Description copied from class: RandomVariable

Tighten the maximum value for a random variable given a string. If there is no maximum value, it will be set. Otherwise the maximum of the allowed range will not increase. The string argument is a number in a format acceptable to the constructors for Integer, Long, or Double as appropriate.

Specified by:

tightenMaximumS in interface RandomVariableOps<BRV extends BooleanRandomVariable>

Specified by:

tightenMaximumS in class RandomVariable<BRV extends BooleanRandomVariable>

Parameters:

s - 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

stream

public Stream<BRV> stream(long size)

Description copied from class: RandomVariableRV

Get a fixed-length stream of random variables.

Overrides:

stream in class RandomVariableRV<Boolean,BRV extends BooleanRandomVariable>

Parameters:

size - the number of random values to provide

Returns:

the stream

parallelStream

public Stream<BRV> parallelStream(long size)

Description copied from class: RandomVariableRV

Get a fixed-length parallel stream of random variables.

Overrides:

parallelStream in class RandomVariableRV<Boolean,BRV extends BooleanRandomVariable>

Parameters:

size - the number of random values to provide

Returns:

the stream
