Constructor Detail

ExceptionColumnImpl

public ExceptionColumnImpl(String aKey)

Creates an ExceptionColumnImpl which will consider the stack trace in its string representation #toStorageString(Throwable).

Parameters:

aKey - The key for the ExceptionColumnImpl.

ExceptionColumnImpl

public ExceptionColumnImpl(String aKey,
                           PrintStackTrace aPrintStackTrace)

Creates an ExceptionColumnImpl which can consider or omit the stack trace in its string representation #toStorageString(Throwable).

Parameters:

hasStackTrace - When true then the stack trace in its string representation #toStorageString(Throwable) is considered.

aKey - The key for the ExceptionColumnImpl.

Method Detail

toStorageStrings

public String[] toStorageStrings(Throwable aValue)

Description copied from interface: Column

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<Throwable>

Parameters:

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

Returns:

The String array representation of the value.

fromStorageStrings

public Throwable fromStorageStrings(String[] aStringValues)
                             throws ParseException

Description copied from interface: Column

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 #fromStorageString(Object) may be used instead.

Specified by:

fromStorageStrings in interface Column<Throwable>

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

toPrintable

public String toPrintable(Throwable aValue)

Description copied from interface: Column

A Column implementation can provide its own printable format of the given objects; for example a human readable text representation of the value (or in very specialized cases even enriched with ANSI escape codes). This method enables the Column to convert a value of the given type to a human readable text. The human readable text, in comparison to the method #toString() (or #toStorageFormat(Object)) is not intended to be converted back to the actual value (not bijective). This method may be used a Header instance's method Header.toPrintable(Record).

Specified by:

toPrintable in interface Column<Throwable>

Overrides:

toPrintable in class AbstractColumn<Throwable>

Parameters:

aValue - the element to be converted to a human readable text.

Returns:

The human readable representation of the value.

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class AbstractColumn<Throwable>

Throws:

CloneNotSupportedException
