Constructor Detail

Matrix

protected Matrix(int rowDimension,
                 int columnDimension)

Initializes a new instance with the specified dimensions.

Parameters:

rowDimension - The number of rows in the new matrix.

columnDimension - The number of columns in the new matrix.

Throws:

ArgumentOutOfRangeException - Thrown when rowDimension or columnDimension are less than zero.

Matrix

protected Matrix(@Nonnull
                 Matrix existingInstance,
                 @Nonnull
                 CopyContext context)

Initializes a new instance as a copy of an existing instance.

See ICloneWithContext.clone(CopyContext) for more information about how to implement this constructor in a derived class.

Method Detail

checkForSameDefinition

protected final boolean checkForSameDefinition(DefinitionalObject other)

Checks to determine if another instance has the same definition as this instance and returns true if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Specified by:

checkForSameDefinition in class DefinitionalObject

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

checkForSameDefinition

protected abstract boolean checkForSameDefinition(Matrix other)

Checks to determine if another instance has the same definition as this instance and returns true if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

computeCurrentDefinitionHashCode

protected int computeCurrentDefinitionHashCode()

Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the Matrix.checkForSameDefinition(agi.foundation.infrastructure.DefinitionalObject) method.

Overrides:

computeCurrentDefinitionHashCode in class DefinitionalObject

Returns:

The computed hash code.

getFrozenCopy

@Nonnull
public final Matrix getFrozenCopy()

Gets a frozen copy of this Matrix. If this matrix is already frozen it returns a reference to itself, otherwise it clones itself, freezes the clone, and returns that object.

Returns:

transpose

@Nonnull
public abstract Matrix transpose()

Creates a new Matrix which is the transpose of the current matrix.

Returns:

The new matrix.

multiply

@Nonnull

Returns:

The new matrix.

Indicates whether each cell value of another instance of this type is within the required tolerance of the corresponding coordinate value of this instance.

Specified by:

equalsEpsilon in interface IEquatableEpsilon<Matrix>

Parameters:

other - The Matrix to compare to this instance.

epsilon - The limit at which the absolute differences between the coordinate values will not be considered equal.
