Method Detail

offset

protected int offset()

Description copied from class: BufferDataSet

return the offset, in bytes, of the element.

Overrides:

offset in class BufferDataSet

Returns:

the offset, in bytes, of the element.

offset

protected int offset(int i0)

Description copied from class: BufferDataSet

return the offset, in bytes, of the element. We do not check the dataset rank, so that trim and slice may find the location of any record.

Overrides:

offset in class BufferDataSet

Returns:

the offset, in bytes, of the element.

offset

protected int offset(int i0,
                     int i1)

Description copied from class: BufferDataSet

return the offset, in bytes, of the element.

Overrides:

offset in class BufferDataSet

Parameters:

i0 - first index

i1 - second index

Returns:

the offset, in bytes, of the element.

value

public double value()

Description copied from interface: QDataSet

rank 0 accessor.

Specified by:

value in interface QDataSet

Specified by:

value in class BufferDataSet

Returns:

the value, see the property UNITS to interpret this.

value

public double value(int i0)

Description copied from interface: QDataSet

rank 1 accessor.

Specified by:

value in interface QDataSet

Specified by:

value in class BufferDataSet

Parameters:

i0 - 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

Specified by:

value in class BufferDataSet

Parameters:

i0 - the index

i1 - the index

Returns:

the value, see the property UNITS to interpret this.

value

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

Description copied from interface: QDataSet

rank 3 accessor.

Specified by:

value in interface QDataSet

Specified by:

value in class BufferDataSet

Parameters:

i0 - the index

i1 - the index

i2 - 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

Specified by:

value in class BufferDataSet

Parameters:

i0 - the index

i1 - the index

i2 - the index

i3 - the index

Returns:

the value, see the property UNITS to interpret this.

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

Overrides:

rank in class BufferDataSet

Returns:

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

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 BufferDataSet

Parameters:

i - the index

Returns:

the length of the second dimension at index i.

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 BufferDataSet

Returns:

the length of the first dimension
