dsto.dfc.swing.text.selection
Class NumberSelector

java.lang.Object
  dsto.dfc.swing.text.selection.NumberSelector

All Implemented Interfaces:

Convertable, PatternSelector, Selector, Serializable

public class NumberSelector
extends Object
implements PatternSelector, Convertable, Serializable

Uses patterns such as "[0:1],10,>=12,(13:*],<200" to match numbers (int, float and double). When using ranges, '(' and ')' indicate non-inclusivity, '[' and ']' indicate inclusivity. Grammar:

 
   <expr>       ::= <term> (',' <term>)*
   <term>       ::= <comparison> | <range>
   <comparison> ::= ('>' | '>=' | '<' | '<=') <number>
   <range>      ::= <value> |  ( '[' | '(' ) <value> ':' <value> ( ')' | ']' )
   <value>      ::= '*' | <number>
   <number>     ::= [+-][0-9]+['.' [0-9]+]
