public class BigDecimalFormatter
extends NumberFormatter

This class provides formatting of BigDecimal values in a FormattedText.

BigDecimalFormatter returns different numeric types based on the current value in the Text field. BigDecimalFormatter is an override of NumberFormatter allowing to guaranty to always return BigDecimal values (Object.toString()).

Method Summary

Modifier and Type	Method	Description
java.lang.Object	getValue()	Returns the current value of the text control if it is a valid BigDecimal.
java.lang.Class<java.math.BigDecimal>	getValueType()	Returns the type of value this ITextFormatter handles, i.e. returns in getValue(). A BigDecimalFormatter always returns an BigDecimal value.

Constructor Details

BigDecimalFormatter

public BigDecimalFormatter()

Constructs a new instance with all defaults.

See Also:

NumberFormatter()

BigDecimalFormatter

public BigDecimalFormatter(java.util.Locale loc)

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

Parameters:

loc - the locale

BigDecimalFormatter

public BigDecimalFormatter(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

BigDecimalFormatter

public BigDecimalFormatter(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

BigDecimalFormatter

public BigDecimalFormatter(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

BigDecimalFormatter

public BigDecimalFormatter(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 BigDecimal. 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 BigDecimal value if valid, else null

See Also:

ITextFormatter.getValue()

getValueType

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

Returns the type of value this ITextFormatter handles, i.e. returns in getValue().
A BigDecimalFormatter always returns an BigDecimal value.

Specified by:

getValueType in interface ITextFormatter

Overrides:

getValueType in class NumberFormatter

Returns:

The value type.

setPatterns

protected void setPatterns(java.lang.String edit, java.lang.String display, java.util.Locale loc)

Sets the patterns and initializes the technical attributes used to manage the operations.

Override the NumberFormatter implementation to handle large numbers.

Overrides:

setPatterns in class NumberFormatter

Parameters:

edit - edit pattern

display - display pattern

loc - Locale to use

Throws:

java.lang.IllegalArgumentException - if a pattern is invalid
