Class WeightsDataSet

java.lang.Object
  org.virbo.dataset.WeightsDataSet

All Implemented Interfaces:

QDataSet

public class WeightsDataSet
extends java.lang.Object
implements QDataSet

Provide consistent valid logic to operators by providing a QDataSet with 1.0 where the data is valid, and 0.0 where the data is invalid. VALID_MIN, VALID_MAX and FILL_VALUE properties are used. Note, when FILL_VALUE is not specified, -1e31 is used. This is to support legacy logic. For convenience, the property FILL_VALUE is set to the fill value used.

Method Detail

rank

public int rank()

Description copied from interface: QDataSet

returns the rank of the dataset, which is the number of indeces used to access data. Only rank 1, 2, and 3 datasets are supported in the interface. When a dataset's rank is 4 or greater, it should implement the HighRankDataSet interface which affords a slice operation to reduce rank. When a dataset's rank is 0, it should implement the RankZeroDataSet interface, which has a no-argument accessor. (TODO: Note that rank 0 and rank N have very limited use, so many routines aren't coded to handle them.)

Specified by:

rank in interface QDataSet

value

public double value(int i)

Description copied from interface: QDataSet

rank 1 accessor.

Specified by:

value in interface QDataSet

value

public double value(int i0,
                    int i1)

Description copied from interface: QDataSet

rank 2 accessor.

Specified by:

value in interface QDataSet

value

public double value(int i0,
                    int i1,
                    int i2)

Description copied from interface: QDataSet

rank 3 accessor.

Specified by:

value in interface QDataSet

property

public java.lang.Object property(java.lang.String name)

Description copied from interface: QDataSet

accessor for properties attached to the dataset. See final static members for example properties.

Specified by:

property in interface QDataSet

property

public java.lang.Object property(java.lang.String name,
                                 int i)

Description copied from interface: QDataSet

accessor for properties attached to the dataset's first index. These properties override (or shadow) properties attached to the dataset, and often implementations will simply return the result of the no-index accessor.

Specified by:

property in interface QDataSet

property

public java.lang.Object property(java.lang.String name,
                                 int i0,
                                 int i1)

Description copied from interface: QDataSet

accessor for properties attached to the dataset's second index. These properties override (or shadow) properties attached to the dataset's first index, and often implementations will simply return the result of the one-index (or zero-index) accessor.

Specified by:

property in interface QDataSet

length

public int length()

Description copied from interface: QDataSet

return the length of the first dimension

Specified by:

length in interface QDataSet

length

public int length(int i)

Description copied from interface: QDataSet

return the length of the second dimension, for the ith element of the first dimension

Specified by:

length in interface QDataSet

length

public int length(int i,
                  int j)

Description copied from interface: QDataSet

return the length of the third dimension, for the ith element of the first dimension and jth element of the second dimension.
