Constructor Detail

LoopStarTable

public LoopStarTable(String colName,
                     double start,
                     double end,
                     double step,
                     Boolean isInteger)

Constructs a loop table from values like the initialisers of a for loop. The isInteger parameter may be set True for an integer column, False for a Double column, and null if the type is to be determined from the input values (integer if all are integers). Integer columns are 32-bit if the values permit, otherwise 64-bit.

Parameters:

colName - name of the single column name in the table

start - initial (row 0) value of variable

end - value which variable will not exceed

step - per-row increment of variable

Method Detail

getRowCount

public long getRowCount()

Description copied from class: ColumnStarTable

Gets the number of rows in the table (which must be applicable to all the columns). Since this is a RandomStarTable the return value must be non-negative.

Specified by:

getRowCount in interface StarTable

Specified by:

getRowCount in class ColumnStarTable

Returns:

number of rows
