Method Detail

getSubIntervalCount

public int getSubIntervalCount(int row,
                               int column)

Returns the number of sub-intervals for a given item.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

Returns:

the sub-interval count.

getSubIntervalCount

public int getSubIntervalCount(java.lang.Comparable rowKey,
                               java.lang.Comparable columnKey)

Returns the number of sub-intervals for a given item.

Parameters:

rowKey - the row key.

columnKey - the column key.

Returns:

the sub-interval count.

getStartValue

public java.lang.Number getStartValue(int row,
                                      int column,
                                      int subinterval)

Returns the start value of a sub-interval for a given item.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

subinterval - the sub-interval index (zero-based).

Returns:

the start value (possibly null).

getStartValue

public java.lang.Number getStartValue(java.lang.Comparable rowKey,
                                      java.lang.Comparable columnKey,
                                      int subinterval)

Returns the start value of a sub-interval for a given item.

Parameters:

rowKey - the row key.

columnKey - the column key.

subinterval - the sub-interval.

Returns:

the start value (possibly null).

getEndValue

public java.lang.Number getEndValue(int row,
                                    int column,
                                    int subinterval)

Returns the end value of a sub-interval for a given item.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

subinterval - the sub-interval.

Returns:

the end value (possibly null).

getEndValue

public java.lang.Number getEndValue(java.lang.Comparable rowKey,
                                    java.lang.Comparable columnKey,
                                    int subinterval)
