Method Detail

getValue

public java.lang.Object getValue()

Returns the current value of the text control if it is a valid Integer. 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 number value if valid, null else

getValueType

public java.lang.Class<java.lang.Integer> getValueType()

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

Specified by:

getValueType in interface ITextFormatter

Overrides:
