Field Detail

pos

protected final int[] pos

ci

protected RolapResult.CellInfo ci

Constructor Detail

RolapCell

RolapCell(RolapResult result,
          int[] pos,
          RolapResult.CellInfo ci)

Creates a RolapCell.

Parameters:

result - Result cell belongs to

pos - Coordinates of cell

ci - Cell information, containing value et cetera

Method Detail

getCoordinateList

public java.util.List<java.lang.Integer> getCoordinateList()

Description copied from interface: Cell

Returns the coordinates of this Cell in its Result.

Specified by:

getCoordinateList in interface Cell

Returns:

Coordinates of this Cell

getValue

public java.lang.Object getValue()

Description copied from interface: Cell

Returns the cell's raw value. This is useful for sending to further data processing, such as plotting a chart.

The value is never null. It may have various types:

• if the cell is null, the value is Util.nullValue;
• if the cell contains an error, the value is an instance of Throwable;
• otherwise, the type of this value depends upon the type of measure: possible types include BigDecimal, Double, Integer and String.

Specified by:

getValue in interface Cell

getCachedFormatString

public java.lang.String getCachedFormatString()

Description copied from interface: Cell

Return the cached formatted string, that survives an aggregate cache clear.

Specified by:

getCachedFormatString in interface Cell

getFormattedValue

public java.lang.String getFormattedValue()

Description copied from interface: Cell

Returns the cell's value formatted according to the current format string, and locale-specific settings such as currency symbol. The current format string may itself be derived via an expression. For more information about format strings, see Format.

Specified by:

getFormattedValue in interface Cell

isNull

public boolean isNull()

Description copied from interface: Cell

Returns whether the cell's value is null.

Specified by:

isNull in interface Cell

isError

public boolean isError()

Description copied from interface: Cell

Returns whether the cell's calculation returned an error.

Specified by:

isError in interface Cell

getDrillThroughSQL

public java.lang.String getDrillThroughSQL(boolean extendedContext)

Create an sql query that, when executed, will return the drill through data for this cell. If the parameter extendedContext is true, then the query will include all the levels (i.e. columns) of non-constraining members (i.e. members which are at the "All" level). If the parameter extendedContext is false, the query will exclude the levels (coulmns) of non-constraining members.

Specified by:

getDrillThroughSQL in interface Cell

getDrillThroughCount

public int getDrillThroughCount()

Description copied from interface: Cell

Returns the number of fact table rows which contributed to this Cell.

Specified by:

getDrillThroughCount in interface Cell

canDrillThrough

public boolean canDrillThrough()

Returns whether it is possible to drill through this cell. Drill-through is possible if the measure is a stored measure and not possible for calculated measures.

Specified by:

canDrillThrough in interface Cell

Returns:

true if can drill through

chooseDrillThroughCube

public static RolapCube chooseDrillThroughCube(Member[] currentMembers,
                                               RolapCube defaultCube)

getPropertyValue

public java.lang.Object getPropertyValue(java.lang.String propertyName)

Description copied from interface: Cell

Returns the value of a property.

Specified by:

getPropertyValue in interface Cell

Parameters:

propertyName - Case-sensitive property name

Returns:

Value of property

getContextMember

public Member getContextMember(Dimension dimension)

Description copied from interface: Cell

Returns the context member for a particular dimension. The member is defined as follows (note that there is always a member):

• If the dimension appears on one of the visible axes, the context member is simply the member on the current row or column.
• If the dimension appears in the slicer, the context member is the member of that dimension in the slier.
• Otherwise, the context member is the default member of that dimension (usually the 'all' member).

Specified by:

getContextMember in interface Cell

setValue

public void setValue(Scenario scenario,
                     java.lang.Object newValue,
                     AllocationPolicy allocationPolicy,
                     java.lang.Object... allocationArgs)

Description copied from interface: Cell

Helper method to implement Cell.setValue(java.lang.Object, org.olap4j.AllocationPolicy, java.lang.Object...).

Specified by:

setValue in interface Cell

Parameters:

scenario - Scenario

newValue - New value

allocationPolicy - Allocation policy

allocationArgs - Arguments for allocation policy
