Class TransposeRankNDataSet

java.lang.Object

org.das2.qds.AbstractDataSet

org.das2.qds.util.TransposeRankNDataSet

All Implemented Interfaces:

MutablePropertyDataSet, QDataSet

public class TransposeRankNDataSet
extends AbstractDataSet

wrap a qube dataset to transpose the indeces. This brute force implementation calculates the index mapping and is implemented without copying. For rank 4 datasets, order[0] must equal 0.

Constructor Detail

TransposeRankNDataSet

public TransposeRankNDataSet(QDataSet source,
                             int[] order)

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 0, 1, 2, 3, and 4 datasets are supported in the interface. When a dataset's rank is 5 or greater, it should implement the HighRankDataSet interface which affords a slice operation to reduce rank.

Specified by:

rank in interface QDataSet

Specified by:

rank in class AbstractDataSet

Returns:

the rank, or number of indeces used to access data.

value

public double value(int i)

Description copied from interface: QDataSet

rank 1 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i - the index

Returns:

the value, see the property UNITS to interpret this.

value

public double value(int i0,
                    int i1)

Description copied from interface: QDataSet

rank 2 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i0 - the index

i1 - the index

Returns:

the value, see the property UNITS to interpret this.

value

public double value(int i1,
                    int i2,
                    int i3)

Description copied from interface: QDataSet

rank 3 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i1 - the index

i2 - the index

i3 - the index

Returns:

the value, see the property UNITS to interpret this.

value

public double value(int i0,
                    int i1,
                    int i2,
                    int i3)

Description copied from interface: QDataSet

rank 4 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i0 - the index

i1 - the index

i2 - the index

i3 - the index

Returns:

the value, see the property UNITS to interpret this.

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

Overrides:

property in class AbstractDataSet

Parameters:

name - property name, such as "DEPEND_0" or "UNITS"

Returns:

the value

See Also:

QDataSet.DEPEND_0, QDataSet.UNITS

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. Note: properties of higher dimension are accessible only by slicing.

Specified by:

property in interface QDataSet

Overrides:

property in class AbstractDataSet

Parameters:

name - property name, such as "DEPEND_0" or "UNITS"

i - the index

Returns:

the value

See Also:

QDataSet.DEPEND_0, QDataSet.UNITS

length

public int length()

Description copied from interface: QDataSet

return the length of the first dimension

Specified by:

length in interface QDataSet

Overrides:

length in class AbstractDataSet

Returns:

the length of the first dimension

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. Note if there are zero elements in the first dimension, but this is a QUBE, then this should not throw an IndexOutOfBoundsException.

Specified by:

length in interface QDataSet

Overrides:

length in class AbstractDataSet

Parameters:

i - the index

Returns:

the length of the second dimension at index i.

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.

Specified by:

length in interface QDataSet

Overrides:

length in class AbstractDataSet

Parameters:

i - the index

j - the index

Returns:

the length of the third dimension at index i.

length

public int length(int i,
                  int j,
                  int k)

Description copied from interface: QDataSet

return the length of the fourth dimension for the ith, jth and kth elements of the first three dimensions.

Specified by:

length in interface QDataSet

Overrides:

length in class AbstractDataSet

Parameters:

i - the index

j - the index

k - the index

Returns:

the length of the fourth dimension for the ith, jth and kth elements of the first three dimensions.
