Constructor Detail

IntegerColumnImpl

public IntegerColumnImpl(String aKey)

Creates a IntegerColumnImpl managing Integer instances.

Parameters:

aKey - The key for the IntegerColumnImpl.

Method Detail

toStorageStrings

public String[] toStorageStrings(Integer aValue)

A Column implementation can provide its own text exchange format for the given objects. This method enables the Column to convert a value of the given type to a String array and via Column.fromStorageStrings(String[]) back to the value (bijective). This method supports data sinks (such as Amazon's SimpleDb) which provide dedicated support for multiple values in a row's entry: In case T is an array type, then the storage String representations of the elements in that array may be placed in dedicated entries of the returned String array. In case T is not an array type then the returned String array may contain just one value. In case data sinks (such as relational databases) are to be addressed which allow only a single value in a row's entry, then the method Column.toStorageString(Object) may be used instead.

Specified by:

toStorageStrings in interface Column<Integer>

Parameters:

aValue - the element to be converted to a String array.

Returns:

The String array representation of the value.

fromStorageStrings

public Integer fromStorageStrings(String[] aStringValues)
                           throws ParseException

A Column implementation can provide its own text exchange format for the given objects. This method enables the Column to convert a String array value to a value of the given type and via Column.toStorageStrings(Object) back to the String array (bijective). This method supports data sinks (such as Amazon's SimpleDb) which provide dedicated support for multiple values in a row's entry: In case T is an array type, then the storage String representations of the elements in that array may be placed in dedicated entries of the provided String array. In case T is not an array type then the passed String array may contain just one value. In case data sinks (such as relational databases) are to be addressed which allow only a single value in a row's entry, then the method Column.fromStorageString(String) may be used instead.

Specified by:

fromStorageStrings in interface Column<Integer>

Parameters:

aStringValues - The value to be converted to a type instance.

Returns:

The type representation of the value.

Throws:

ParseException - in case parsing the String was not possible

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class AbstractColumn<Integer>

Throws:

CloneNotSupportedException
