Constructor Detail

MutableDoubleVector

protected MutableDoubleVector(U unit)

Construct a new MutableDoubleVector.

Parameters:

unit - U; the unit of the new MutableDoubleVector

Method Detail

checkCopyOnWrite

protected final void checkCopyOnWrite()

Check the copyOnWrite flag and, if it is set, make a deep copy of the data and clear the flag.

setSI

public final void setSI(int index,
                        double valueSI)
                 throws ValueException

Replace the value at index by the supplied value which is expressed in the standard SI unit.

Specified by:

setSI in interface MutableDoubleVectorInterface<U extends Unit<U>>

Parameters:

index - int; index of the value to replace

valueSI - double; the value to store (expressed in the standard SI unit)

Throws:

ValueException - when index out of range (index < 0 or index >= size())

set

public final void set(int index,
                      DoubleScalar<U> value)
               throws ValueException

Replace the value at index by the supplied value which is in a compatible unit.

Specified by:

set in interface MutableDoubleVectorInterface<U extends Unit<U>>

Parameters:

index - int; index of the value to replace

value - DoubleScalar<U>; the strongly typed value to store

Throws:

ValueException - when index out of range (index < 0 or index >= size())

setInUnit

public final void setInUnit(int index,
                            double value,
                            U valueUnit)
                     throws ValueException

Replace the value at index by the supplied value which is expressed in a supplied (compatible) unit.

Specified by:

setInUnit in interface MutableDoubleVectorInterface<U extends Unit<U>>

Parameters:

index - int; index of the value to replace

value - double; the value to store (which is expressed in valueUnit)

valueUnit - U; unit of the supplied value

Throws:

ValueException - when index out of range (index < 0 or index >= size())

assign

public final void assign(DoubleFunction doubleFunction)

Execute a function on a cell by cell basis. Note: because many functions have to act on zero cells or can generate cells with a zero value, the functions have to be applied on a dense dataset which has to be transformed back to a dense dataset if necessary.

Parameters:

doubleFunction - the function to apply

incrementByImpl

protected final MutableDoubleVector<U> incrementByImpl(DoubleVector.Rel<U> rel)
                                                throws ValueException

Increment the values in this MutableDoubleVector by the corresponding values in a Relative DoubleVector.
Only Relative values are allowed; adding an Absolute value to an Absolute value is not allowed. Adding an Absolute value to an existing Relative value would require the result to become Absolute, which is a type change that is impossible. For that operation use a static method.

Parameters:

rel - DoubleVector.Rel<U>; the Relative DoubleVector

Returns:

MutableDoubleVector<U>; this modified MutableDoubleVector

Throws:

ValueException - when the vectors do not have the same size

decrementByImpl

protected final MutableDoubleVector<U> decrementByImpl(DoubleVector.Rel<U> rel)
                                                throws ValueException

Decrement the corresponding values of this Relative DoubleVector from the values of this MutableDoubleVector.
Only Relative values are allowed; subtracting an Absolute value from a Relative value is not allowed. Subtracting an Absolute value from an existing Absolute value would require the result to become Relative, which is a type change that is impossible. For that operation use a static method.

Parameters:

rel - DoubleVector.Rel<U>; the Relative DoubleVector

Returns:

MutableDoubleVector<U>; this modified MutableDoubleVector

Throws:

ValueException - when the vectors do not have the same size

scaleValueByValue

protected final void scaleValueByValue(DoubleVector<?> factor)
                                throws ValueException

Scale the values in this MutableDoubleVector by the corresponding values in a DoubleVector.

Parameters:

factor - DoubleVector<?>; contains the values by which to scale the corresponding values in this MutableDoubleVector

Throws:

ValueException - when the vectors do not have the same size

scaleValueByValue

protected final MutableDoubleVector<U> scaleValueByValue(double[] factor)
                                                  throws ValueException

Scale the values in this MutableDoubleVector by the corresponding values in a double array.

Parameters:

factor - double[]; contains the values by which to scale the corresponding values in this MutableDoubleVector

Returns:

MutableDoubleVector<U>; this modified MutableDoubleVector

Throws:

ValueException - when the vector and the array do not have the same size

normalize

public final void normalize()
                     throws ValueException

Normalize the vector, i.e. scale the values to make the sum equal to 1.

Specified by:

normalize in interface MutableDoubleVectorInterface<U extends Unit<U>>

Throws:

ValueException - when the sum of the values is zero and normalization is not possible
