Method Detail

type

default DataType type()

Description copied from interface: BaseVector

Returns the element type.

Specified by:

type in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

array

float[] array()

Description copied from interface: BaseVector

Returns the array that backs this vector. This is mostly for smile internal use for high performance. The application developers should not use this method.

Specified by:

array in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

get

FloatVector get(int... index)

Description copied from interface: BaseVector

Returns a new vector with selected entries.

Specified by:

get in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

Parameters:

index - the index of selected entries.

getByte

default byte getByte(int i)

Description copied from interface: BaseVector

Returns the byte value at position i.

Specified by:

getByte in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

getShort

default short getShort(int i)

Description copied from interface: BaseVector

Specified by:

getShort in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

getInt

default int getInt(int i)

Description copied from interface: BaseVector

Returns the integer value at position i.

Specified by:

getInt in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

getLong

Specified by:

getLong in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

getDouble

default double getDouble(int i)

Description copied from interface: BaseVector

Returns the double value at position i.

Specified by:

getDouble in interface BaseVector<java.lang.Float,java.lang.Double,java.util.stream.DoubleStream>

toString

default java.lang.String toString(int n)

Returns the string representation of vector.

Parameters:

n - Number of elements to show

of

static FloatVector of(java.lang.String name,
                      float[] vector)

Creates a named float vector.

Parameters:
