Types

type BooleanIterator

type BooleanIterator struct {
	Values []*array.Boolean
	// contains filtered or unexported fields
}

func IterateBooleans

func IterateBooleans(arrs []array.Interface) BooleanIterator

func (*BooleanIterator) IsEmpty

func (i *BooleanIterator) IsEmpty() bool

IsEmpty returns true if the iterator has no values to read.

func (*BooleanIterator) IsNull

func (i *BooleanIterator) IsNull() bool

IsNull returns if the current value is null.

func (*BooleanIterator) IsValid

func (i *BooleanIterator) IsValid() bool

IsValid returns if the current value is valid.

func (*BooleanIterator) Next

func (i *BooleanIterator) Next() bool

Next will move to the next value. It will return false if there are no more values to be read. This will initialize the iterator if this is the first time it is called and return true if there is at least one element.

func (*BooleanIterator) Value

func (i *BooleanIterator) Value() bool

Value returns the current value in the iterator.

type Float64Iterator

type Float64Iterator struct {
	Values []*array.Float64
	// contains filtered or unexported fields
}

func IterateFloat64s

func IterateFloat64s(arrs []array.Interface) Float64Iterator

func (*Float64Iterator) IsEmpty

func (i *Float64Iterator) IsEmpty() bool

IsEmpty returns true if the iterator has no values to read.

func (*Float64Iterator) IsNull

func (i *Float64Iterator) IsNull() bool

IsNull returns if the current value is null.

func (i *Float64Iterator) IsValid() bool

IsValid returns if the current value is valid.

func (*Float64Iterator) Next

func (i *Float64Iterator) Next() bool

Next will move to the next value. It will return false if there are no more values to be read. This will initialize the iterator if this is the first time it is called and return true if there is at least one element.
