Description copied from interface: IHeaderTable

Gets the names of each column.

Specified by:

columnNames in interface IHeaderTable<T>

Returns:

The names of each column.

columnToIndex

public int columnToIndex(String column)

Description copied from interface: IHeaderTable

Converts a column name to an index.

Specified by:

columnToIndex in interface IHeaderTable<T>

Overrides:

columnToIndex in class AbstractHeaderTable<T>

Parameters:

column - The column name.

Returns:

The index of the column.

hasColumn

public boolean hasColumn(String column)

Description copied from interface: IHeaderTable

Checks if the table has a column with the given name.

Specified by:

hasColumn in interface IHeaderTable<T>

Overrides:

hasColumn in class AbstractHeaderTable<T>

Parameters:

column - The name of the column.

public List<List<T>> rows()

Description copied from interface: IHeaderTable

Returns all rows;

Specified by:

rows in interface IHeaderTable<T>

Returns:

All rows.

toString

public String toString()

Overrides:

toString in class Object

fromRows

public static <T> IHeaderTable<T> fromRows(Iterable<? extends Iterable<? extends T>> rows)

Creates a new table from the given rows of cell values. Uses the column index as the header name. Fills missing cells with null.

Type Parameters:

T - The type of the cell values.

Parameters:

rows - The rows of cell values.

Returns:

A new table from the given rows of cell values.

fromRows

public static <T> IHeaderTable<T> fromRows(Iterable<? extends Iterable<? extends T>> rows,
                                           Supplier<? extends T> defaultValue)

Creates a new table from the given rows of cell values. Uses the column index as the header name. Fills missing cells with the given default value.

Type Parameters:

T - The type of the cell values.

Parameters:

rows - The rows of cell values.

defaultValue - Supplier for the default value for missing cells. When null, null is used as the default value.

Returns:

A new table from the given rows of cell values.

fromRows

public static IHeaderTable<String> fromRows(Iterable<? extends Iterable<String>> rows,
                                            Supplier<String> defaultValue,
                                            boolean firstRowIsHeader)

Creates a new table from the given rows of cell values. Uses the first row as the names for the header when the first-row-is-header flag is true. Otherwise, uses the column index as the header name. Fills missing cells with the given default value.

Parameters:

rows - The rows of cell values.

defaultValue - Supplier for the default value for missing cells. When null, null is used as the default value.

Returns:

A new table from the given rows of cell values.

fromRows

public static <T> IHeaderTable<T> fromRows(Iterable<? extends Iterable<? extends T>> rows,
                                           Supplier<? extends T> defaultValue,
                                           Function<? super T,String> headerNameExtractor)

Creates a new table from the given rows of cell values. When the given header name extractor is non-null, uses the first row as the names for the header. Otherwise, uses the column index as the header name. Fills missing cells with the given default value.

Type Parameters:

T - The type of the cell values.

Parameters:

rows - The rows of cell values.

defaultValue - Supplier for the default value for missing cells. When null, null is used as the default value.

headerNameExtractor - Extractor for the header name. When null, the column index is used as the header name.

Returns:

A new table from the given rows of cell values.
