org.jdesktop.binding.metadata.NumberMetaData

Class for representing meta-data for a numerical data field which is one of the following types:

java.lang.Integer
java.lang.Long
java.lang.Short
java.lang.Float
java.lang.Double

This meta-data class defines additional properties and edit constraints which are applicable to numerical values, such as minimum, maximum, whether or not the value is a currency, etc. Example usage:

 NumberMetaData metaData = new NumberMetaData("interestrate", Float.class, "Interest Rate"); metaData.setMinimum(new Float(4.5)); metaData.setMaximum(new Float(6.8));

Setting a minimum and/or maximum constraint will implicitly cause a range validator to be added to the meta-data object.
