Public Methods

Method	Description
alphaChars ( ) : Generator	creates a generator that produces only alphabetic characters
alphaNumChars ( ) : Generator	creates a generator that produces alphanumeric characters
alphaNumStrings ( ) : Generator	creates a generator that produces alphanumeric strings
alphaStrings ( ) : Generator	creates a generator that produces alphabetic strings
any ( )
anyPrintable ( )
arraysOf ( self $gen ) : Generator	creates a generator that produces arrays whose elements are chosen from $gen.
asciiChars ( ) : Generator	creates a generator that produces only ASCII characters
asciiStrings ( ) : Generator	creates a generator that produces ASCII strings
bind ( callable $k ) : Generator	creates a new generator that passes the result of this generator to the callable $k which should return a new generator.
booleans ( ) : Generator	creates a generator that produces true or false. Shrinks to false.
call ( Random $rng, integer $size ) : RoseTree	invokes the generator with the given RNG and size
chars ( ) : Generator	creates a generator that produces characters from 0-255
choose ( integer $lower, integer $upper ) : Generator	creates a generator that returns numbers in the range $lower to $upper, inclusive
containerTypes ( self $innerType )
elements ( ) : Generator	creates a generator that randomly chooses from the specified values
fmap ( callable $f ) : Generator	maps function f over the values produced by this generator
forAll ( array $args, callable $f )
frequency ( ) : Generator	creates a generator that produces values from specified generators based on likelihoods. The likelihood of a generator being chosen is its likelihood divided by the sum of all likelihoods.
intRoseTree ( $val )
intoArrays ( ) : Generator	creates a generator that produces arrays whose elements are chosen from this generator.
ints ( ) : Generator	creates a generator that returns a positive or negative integer bounded by the generators size parameter.
maps ( self $keygen, self $valgen ) : Generator	creates a generator that produces arrays with keys chosen from $keygen and values chosen from $valgen.
mapsFrom ( self $keygen ) : Generator	creates a generator that produces arrays with keys chosen from $keygen and values chosen from this generator.
mapsTo ( self $valgen ) : Generator	creates a generator that produces arrays with keys chosen from this generator and values chosen from $valgen.
mapsWith ( array $map ) : Generator	creates a generator that produces arrays with the same keys as in $map where each corresponding value is chosen from a specified generator.
negInts ( ) : Generator	creates a generator that produces negative integers bounded by the generators size parameter.
notEmpty ( $maxTries = 10 )
oneOf ( ) : Generator	creates a new generator that randomly chooses a value from the list of provided generators. Shrinks toward earlier generators as well as shrinking the generated value itself.
posInts ( ) : Generator	creates a generator that produces positive integers bounded by the generators size parameter.
recursive ( callable $container, self $scalar )
resize ( integer $n ) : Generator	creates a new generator based on this generator with size always bound to $n
samples ( integer $maxSize = 100 ) : Generator	returns an infinite sequence of random samples from this generator bounded by $maxSize
simplePrintableTypes ( )
simpleTypes ( )
sizes ( $maxSize )	--------------------------------------------------
strictlyNegInts ( ) : Generator	creates a generator that produces strictly negative integers bounded by the generators size parameter.
strictlyPosInts ( ) : Generator	creates a generator that produces strictly positive integers bounded by the generators size parameter.
strings ( ) : Generator	creates a generator that produces strings; may contain unprintable chars
suchThat ( callable $pred, integer $maxTries = 10 ) : Generator	creates a new generator that generates values from this generator such that they satisfy callable $pred.
takeSamples ( integer $num = 10 ) : array	returns an array of $num random samples from this generator
tuples ( ) : Generator	creates a new generator that returns an array whose elements are chosen from the list of given generators. Individual elements shrink according to their generator but the array will never shrink in count.
unit ( mixed $value ) : Generator	creates a generator that always returns $value and never shrinks
