JoinDataSet

public JoinDataSet(int dataSetsRank)

Creates a new instance of JoinDataSet

Method Detail

join

public void join(QDataSet ds)

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 i0)

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 i0)

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 i0,
                  int i1)

Description copied from interface: QDataSet
