Constructor Detail

IntegerVector

public IntegerVector(int n)

Initializes the vector to all 0 values.

Parameters:

n - The length of the vector.

IntegerVector

public IntegerVector(int[] x)

Initializes the vector to the specified values.

Parameters:

x - The initial values for the vector.

IntegerVector

public IntegerVector(IntegerVector other)

Initializes the vector as a copy of another.

Parameters:

other - The other vector to copy.

Method Detail

length

public final int length()

Description copied from interface: IntegerValued

Gets the number of parameters.

Specified by:

length in interface IntegerValued

Returns:

The number of parameters for this function.

get

public final int get(int i)

Description copied from interface: IntegerValued

Accesses the current value of a specified parameter.

Specified by:

get in interface IntegerValued

Parameters:

i - The parameter to get.

Returns:

The current value of the i-th parameter.

toArray

public final int[] toArray(int[] values)

Description copied from interface: IntegerValued

Accesses the current values of all of the parameters.

Specified by:

toArray in interface IntegerValued

Parameters:

values - An array to hold the result. If values is null or if values.length is not equal to this.length(), then a new array is constructed for the result.

Returns:

An array containing the current values of all of the parameters.

set

public void set(int i,
                int value)

Description copied from interface: IntegerValued

Sets a function parameter to a specified value.

Specified by:

set in interface IntegerValued

Parameters:

i - The parameter to set.

value - The new value for the i-th parameter.

copy

public IntegerVector copy()

Creates an identical copy of this object.

Specified by:

copy in interface Copyable<IntegerVector>

Returns:

an identical copy of this object

equals

public boolean equals(Object other)

Indicates whether some other object is "equal to" this one. To be equal, the other object must be of the same runtime type and contain the same values.

Overrides:

equals in class Object

Parameters:

other - The other object to compare.

Returns:

true if other is not null, is of the same runtime type as this, and contains the same values.

hashCode

public int hashCode()

Returns a hash code value.

Overrides:

hashCode in class Object

Returns:

a hash code value
