Constructor Details

AIdentityDictionary

public AIdentityDictionary(int nRowCol)

Create an identity matrix dictionary. It behaves as if allocated a Sparse Matrix block but exploits that the structure is known to have certain properties.

Parameters:

nRowCol - The number of rows and columns in this identity matrix.

AIdentityDictionary

public AIdentityDictionary(int nRowCol,
 boolean withEmpty)

Method Details

withEmpty

public boolean withEmpty()

getInMemorySize

public static long getInMemorySize(int numberColumns)

containsValue

public final boolean containsValue(double pattern)

Description copied from interface: IDictionary

Detect if the dictionary contains a specific value.

Specified by:

containsValue in interface IDictionary

Overrides:

containsValue in class ADictionary

Parameters:

pattern - The value to search for

Returns:

true if the value is contained else false.

productAllRowsToDouble

public double[] productAllRowsToDouble(int nCol)

Description copied from interface: IDictionary

Method to product all rows to a column vector.

Specified by:

productAllRowsToDouble in interface IDictionary

Overrides:

productAllRowsToDouble in class ADictionary

Parameters:

nCol - The number of columns in the ColGroup to know how to get the values from the dictionary.

Returns:

A row product

productAllRowsToDoubleWithDefault

public double[] productAllRowsToDoubleWithDefault(double[] defaultTuple)

Description copied from interface: IDictionary

Method to product all rows to a column vector with a default value added in the end.

Specified by:

productAllRowsToDoubleWithDefault in interface IDictionary

Overrides:

productAllRowsToDoubleWithDefault in class ADictionary

Parameters:

defaultTuple - The default row that aggregate to last cell

Returns:

A row product

sort

public int[] sort()

Description copied from interface: IDictionary

Sort the values of this dictionary via an index of how the values mapped previously. In practice this design means we can reuse the previous dictionary for the resulting column group

Returns:

The sorted index.
