Method Detail

of

public static Row of(HeaderDefinition headerDefinition,
                     String[] values)

Create a Row. Items in the values array can be null although the array cannot. If the headerDefinition has a different number of columns than the length of the values array then an IllegalArgumentException will be thrown.

Parameters:

headerDefinition - the row definition, not null

values - the actual values in the row, not null

Returns:

a row instance

getString

public String getString(int index)

Returns an entry from a given column index as a String (possibly null). Throws an ArrayIndexOutOfBoundsException if the index is greater than the number of columns in the header definition

Parameters:

index - the index of the entry, zero-based.

Returns:

the entry, can be null

getString

public String getString(String column)

Returns an entry from a given column name as a String (possibly null). Throws an IllegalArgumentException if the name is not defined in the header definition. Empty is returned as the empty String rather than null.

Parameters:

column - the column name of the entry, not null

Returns:

the entry, can be null

getLocalDate

public org.threeten.bp.LocalDate getLocalDate(int index)

Returns an entry from a given column index as a LocalDate (possibly null). Throws an ArrayIndexOutOfBoundsException if the index is greater than the number of columns in the header definition. Throws a DateTimeParseException if the underlying data is not a date in ISO local date format (YYYY-MM-DD).

Parameters:

index - the index of the entry, zero-based.

Returns:

the entry, can be null if the value is null or empty

getLocalDate

public org.threeten.bp.LocalDate getLocalDate(String column)

Returns an entry from a given column name as a LocalDate (possibly null). Throws an IllegalArgumentException if the name is not defined in the header definition. Throws a DateTimeParseException if the underlying data is not a date in ISO local date format (YYYY-MM-DD).

Parameters:

column - the column name of the entry, not null

Returns:

the entry, can be null if the value is null or empty

getDouble

public Double getDouble(int index)

Returns an entry from a given column index as a Double (possibly null). Throws as ArrayIndexOutOfBoundsException if the index is greater than the number of columns in the header definition. Throws a NumberFormatException if the underlying data can not be parsed as a double precision floating point number.

Parameters:

index - the index of the entry, zero-based

Returns:

the value or null if the value is null or empty

getDouble

public Double getDouble(String column)

Returns an entry from a given column name as a Double (possibly null). Throws an IllegalArgumentException if the name is not defined in the header definition. Throws a NumberFormatException if the underlying data cannot be parsed as a double precision floating point number.

Parameters:

column - the column name of the entry, not null

Returns:

the entry, can be null if the value is null or empty

size

public int size()

Get the number of columns in this row.

Returns:

the number of columns in this row
