Anton Shchyrov commented on THRIFT-4461: ---------------------------------------- Full unit name System.Character. This unit added in Thrift.Utils by scheme {{uses}} {{ \{$IFDEF OLD_UNIT_NAMES}}} {{ Classes, Windows, SysUtils, *Character*, SyncObjs;}} {{ \{$ELSE}}} {{ System.Classes, Winapi.Windows, System.SysUtils, *System.Character*, System.SyncObjs;}} {{ \{$ENDIF}}} If condition OLD_UNIT_NAMES is not defined then compiler will require fully unit name. And identifier Character.IsLowSurrogate will not be defined unlike identifier System.Character.IsLowSurrogate > Invalid compiler directive > -------------------------- > > Key: THRIFT-4461 > URL: https://issues.apache.org/jira/browse/THRIFT-4461 > Project: Thrift > Issue Type: Bug > Components: Delphi - Library > Affects Versions: 0.11.0 > Environment: Delphi XE3 > Reporter: Anton Shchyrov > Assignee: Jens Geyer > Priority: Minor > Labels: delphi > Attachments: Thrift.Utils.diff > > > In module Thrift.Utils daclared two methods > {{class function CharUtils.IsHighSurrogate( const c : Char) : Boolean;}} > {{begin}} > {{ \{$IF CompilerVersion < 23.0}}} > {{ result := Character.IsHighSurrogate( c);}} > {{ \{$ELSE}}} > {{ result := c.IsHighSurrogate();}} > {{ \{$IFEND}}} > {{end;}} > {{class function CharUtils.IsLowSurrogate( const c : Char) : Boolean;}} > {{begin}} > {{ \{$IF CompilerVersion < 23.0}}} > {{ result := Character.IsLowSurrogate( c);}} > {{ \{$ELSE}}} > {{ result := c.IsLowSurrogate;}} > {{ \{$IFEND}}} > {{end;}} > But methods Char.IsHighSurrogate()/Char.IsLowSurrogate() **appeared in Delphi > XE4. For Delphi XE4 variable CompilerVersion equal 25. > In this way condition > {{{$IF CompilerVersion < 23.0}}} > may be changed to > {{{$IF CompilerVersion < *25.0*}}} > And access for unit *Character* may be determined through defiine symbol > *OLD_UNIT_NAMES* -- This message was sent by Atlassian JIRA (v7.6.3#76005)
