Interface StaticColumnTemplateTableInterface

All Superinterfaces:

StaticTableInterface

All Known Subinterfaces:

ColumnTemplateTableInterface

public interface StaticColumnTemplateTableInterface
extends StaticTableInterface

Defines an interface for accessing column template tables. Column template tables are tables where the set of row classes defines a template for each column. In other words, the class of each cell is restricted to the class, or a subclass, of its corresponding row. A transposed SAS data set is an example of such a table.

Method Summary

Method Detail

getRowClass

java.lang.Class getRowClass(int index)
                            throws com.sas.table.TableException

Returns the class of a row. The row is identified by the given index. Null will be returned for rows that do not contain cells of a single class.

Parameters:

index - A one-based index that identifies the row.

Returns:

The specified row's class.

Throws:

TableException - Provides a catch-all for all non-RuntimeExceptions.

java.lang.IndexOutOfBoundsException - Thrown if index is negative, zero, or greater than the number of rows.

getRowClasses

java.lang.Class[] getRowClasses(int startIndex,
                                int count)
                                throws com.sas.table.TableException

Returns the classes for a range of rows. The range of rows is identified by the given index which serves to identify a starting row and by the given row count which defines the extent of the range. The set of classes is returned as an array with each element of the array corresponding to a row in the range. The class of rows that do not contain cells of a single class should be expressed as null.

Parameters:

startIndex - A one-based index which identifies the start of the range.

count - The number of classes to return; defines the extent of the range.

Returns:

The specified rows' classes.

Throws:

TableException - Provides a catch-all for all non-RuntimeExceptions.

java.lang.IndexOutOfBoundsException - Thrown if startIndex or count is negative, zero, or greater than the number of rows except when getRowCount has returned -1. In that case, the implementation should return an array whose length is less than count and the caller should be prepared for this.
