Constructor Details

Doubles

Doubles(Class<? extends Number> type,
 Number first,
 Number increment,
 int length)

Creates a sequence of numbers in a given range of values using the given increment.

Parameters:

type - the type of elements in the sequence.

first - the first value, inclusive.

increment - the difference between the values at two adjacent indexes.

length - the length of the vector.

Method Details

createSubSampling

Vector createSubSampling(int offset,
 int step,
 int n)

Creates a new sequence for a subrange of this vector.

Overrides:

createSubSampling in class Vector

isInteger

public final boolean isInteger()

Returns true if this vector contains only integer values.

Overrides:

isInteger in class Vector

Returns:

true if this vector contains only integer values.

isNaN

public final boolean isNaN(int index)

Returns true if this vector returns NaN values.

Specified by:

isNaN in class Vector

Parameters:

index - the index in the [0 … size-1] range.

Returns:

true if the value at the given index is NaN.

doubleValue

public final double doubleValue(int index)

Computes the value at the given index.

Specified by:

doubleValue in class Vector

Parameters:

index - the index in the [0 … size-1] range.

Returns:

the value at the given index.

See Also:

• Vector.doubleValues()

stringValue

Returns the string representation of the value at the given index.

Specified by:

stringValue in class Vector

Parameters:

index - the index in the [0 … size-1] range.

Returns:

a string representation of the value at the given index (may be null).

See Also:

• Vector.toString()

get

public Number get(int index)

Computes the value at the given index.

Specified by:

get in interface List<Number>

Specified by:

get in class Vector

Parameters:

index - the index in the [0 … size-1] range.

Returns:

the value at the given index (may be null).

increment

public final Number increment(double tolerance)

Returns the increment between all consecutive values.

Overrides:

increment in class Vector

Parameters:

tolerance - the tolerance threshold for verifying if the increment is constant.
