public class BigIntegerFormatter
extends NumberFormatter

This class provides formatting of BigInteger values in a FormattedText.

BigIntegerFormatter returns different numeric types based on the current value in the Text field. BigIntegerFormatter is an override of NumberFormatter allowing to guaranty to always return BigInteger values (Number.longValue()).

Constructor Details

BigIntegerFormatter

public BigIntegerFormatter()

Constructs a new instance with all defaults.

See Also:

NumberFormatter()

BigIntegerFormatter

public BigIntegerFormatter(java.util.Locale loc)

Constructs a new instance with default edit and display masks for the given locale.

Parameters:

loc - the locale

BigIntegerFormatter

public BigIntegerFormatter(java.lang.String editPattern, java.util.Locale loc)

Constructs a new instance with the given edit mask and locale. Display mask is identical to the edit mask.

Parameters:

editPattern - the edit mask

loc - the locale

BigIntegerFormatter

public BigIntegerFormatter(java.lang.String editPattern, java.lang.String displayPattern, java.util.Locale loc)

Constructs a new instance with the given masks and locale.

Parameters:

editPattern - the edit mask

displayPattern - the display mask

loc - the locale

BigIntegerFormatter

public BigIntegerFormatter(java.lang.String editPattern, java.lang.String displayPattern)

Constructs a new instance with the given edit and display masks. Uses the default locale.

Parameters:

editPattern - the edit mask

displayPattern - the display mask

BigIntegerFormatter

public BigIntegerFormatter(java.lang.String editPattern)

Constructs a new instance with the given edit mask. Display mask is identical to the edit mask, and locale is the default one.

Parameters:

editPattern - the edit mask

Method Details

getValue

public java.lang.Object getValue()

Returns the current value of the text control if it is a valid BigInteger. If the buffer is flagged as modified, the value is recalculated by parsing with the nfEdit initialized with the edit pattern. If the number is not valid, returns null.

Specified by:

getValue in interface ITextFormatter

Overrides:

getValue in class NumberFormatter

Returns:

current BigInteger value if valid, else null

See Also:

ITextFormatter.getValue()

getValueType

public java.lang.Class<java.math.BigInteger> getValueType()

Returns the type of value this ITextFormatter handles, i.e. returns in getValue().
An BigIntegerFormatter always returns an BigInteger value.

Specified by:

getValueType in interface ITextFormatter

Overrides:

getValueType in class NumberFormatter

Returns:

The value type.
