public class CsvRow
extends ProxiedList<String>

Class representing the values of one CSV row, implementing List<String> for convenience reasons.

Objects of this type include a back-reference to the parent Csv object and the current row's index. If the parent object is marked unmodifiable, its rows are unmodifiable, too.

For convenience the method get(String) allows to retrieve values by the column's CSV header value.

Csv	getCsv() Reference to the parent CSV object
int	getRowIndex() The current row's index
int	hashCode()
boolean	isModifiable() Flag specifying if this instance can be modified
String	toString() Returns a valid CSV string representation of this object using the default separator and escaper.
String	toString(char separator, char escaper) Returns a valid CSV string representation of this object using separator and escaper.

Method Detail

finalize

protected final void finalize()
                       throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

get

public Optional<String> get(String header)

Returns the current row's value of the column specified by header. Valid headers are specified by the first row of the CSV. In case header is not a valid header or there is no value for the column of the given header, Optional#empty() is returned.

In case multiple headers with the name header exist, the first column is selected.

Parameters:

header - the header name to search for

Returns:

the current row's value of the column specified by header, else empty

isModifiable

public boolean isModifiable()

Flag specifying if this instance can be modified

Specified by:

isModifiable in class ProxiedCollection<String>

Returns:

true if this instance is modifiable, else false

toString

public String toString()

Returns a valid CSV string representation of this object using the default separator and escaper.

Overrides:

toString in class ProxiedCollection<String>

Returns:

a valid CSV representation of this object using default separator and escaper

toString

public String toString(char separator,
                       char escaper)

Returns a valid CSV string representation of this object using separator and escaper.

This is a short-hand method for StringConverters.encodeCsvRow(java.util.Collection, char, char).

Parameters:

separator - the CSV separator

escaper - the CSV value escaper

Returns:

a valid CSV representation of this object using separator and escaper

getCsv

public Csv getCsv()

Reference to the parent CSV object

Returns:

the reference to the parent CSV object

getRowIndex

public int getRowIndex()

The current row's index

Returns:

the current row's index

equals

public boolean equals(@Nullable
                      Object o)

Description copied from class: ProxiedCollection

Specified by:

equals in interface Collection<String>

Specified by:

equals in interface List<String>

Overrides:

equals in class ProxiedCollection<String>

canEqual

protected boolean canEqual(@Nullable
                           Object other)

hashCode

public int hashCode()

Description copied from class: ProxiedCollection

Specified by:

hashCode in interface Collection<String>

Specified by:

hashCode in interface List<String>

Overrides:

hashCode in class ProxiedCollection<String>
