Method Detail

contains

public boolean contains(Object value)

Description copied from interface: DataRange

Check if a data range contains a particular value

Specified by:

contains in interface DataRange<T>

Parameters:

value - the value to check

Returns:

true if the data range contains value, false else

containsAtLeast

public boolean containsAtLeast(int n)

Description copied from interface: DataRange

Check that a data range contains a minimum number of elements

Specified by:

containsAtLeast in interface DataRange<T>

Parameters:

n - the number of elements

Returns:

true if the data range contains n or more elements, false otherwise

getValue

public T getValue(int i)

Description copied from interface: DataRange

Return a value from an enumerable data range. Necessary to support LiteralValueBranch shiftTryNext

Specified by:

getValue in interface DataRange<T>

Parameters:

i - the index of the value in the data range

Returns:

the value

isEmpty

public boolean isEmpty()

Description copied from interface: DataRange

Convenience method equivalent to !containsAtLeast(0)

Specified by:

isEmpty in interface DataRange<T>

Returns:

true if the data range contains no elements, false otherwise

isEnumerable

public boolean isEnumerable()

Description copied from interface: DataRange

Query if values in the data range can be enumerated.

Specified by:

isEnumerable in interface DataRange<T>

Returns:

true if the data range is enumerable, false otherwise

isFinite

public boolean isFinite()

Description copied from interface: DataRange

Query if there are a finite number of values in the data range.

Specified by:

isFinite in interface DataRange<T>

Returns:

true if the data range is finite, false otherwise

size

public int size()

Description copied from interface: DataRange

Return the size of the data range. Necessary to support LiteralValueBranch constructor

Specified by:

size in interface DataRange<T>

Returns:

the size of the data range

valueIterator

public Iterator<T> valueIterator()

Description copied from interface: DataRange

Get a (possibly infinite) iterator over values in the data range.

Specified by:

valueIterator in interface DataRange<T>

Returns:

an Iterator

getDataRange

public DataRange<? extends T> getDataRange()
