Constructor Detail

Slice3DataSet

public Slice3DataSet(QDataSet ds,
                     int index)

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 i0,
                    int i1,
                    int i2)

Description copied from interface: QDataSet

rank 3 accessor.

Specified by:

value in interface QDataSet

Overrides:

value in class AbstractDataSet

Parameters:

i0 - the index

i1 - the index

i2 - 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

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 i0,
                  int i1)

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:

i0 - the index

i1 - the index

Returns:

the length of the third dimension at index i.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
