EDT:EGL Language conversion
EGL language conversion considerations from IBM Rational Business Developer and EGL CE.
| Rational Business Developer | EDT |
| Called program | Not supported |
| DataItem, Stand alone (top level) function |
Not supported right now |
| Datatable, Structured Record, Form, FormGroup |
Not supported |
| Nullable | Nullability is a quality of the field or parameter not the type...similar to how database columns define a column to be nullable or not nullable. See Language Overview / Nullability |
| Rational Business Developer | EDT |
| Default is inout | Default is inout for value type
Default is in for reference type |
| Array default is inout | Array default is in, because array is reference type |
| timestamp without pattern is inout | timestamp without pattern default is in, because timestamp without pattern is reference type |
- EDT:EGL Language Function Return
| Rational Business Developer | EDT |
| Generated Java - A Return statement is not required in the EGL source for a function if the function returns a value. |
Generated Java - A Return statement is required in the EGL source for a function, for all exit points, if the function returns a value. |
| Rational Business Developer | EDT |
| time |
Before 0.8.1 M2: replaced with timestamp |
| interval | Not Supported right now, no replacement |
| money, num, bin |
use Decimal |
| Rational Business Developer | EDT |
| system libraries | all needs to be fully qualified with library name i.e. sysLib, dateTimeLib, serviceLib, xmlLib...etc. |
| currentDate() DateTimeLib.currentDate() |
When you declare aDate data, aDate should be inited with the current date |
| currentTime() DateTimeLib.currentTime() |
Not Supported |
| currentTimeStamp() DateTimeLib.currentTimeStamp() |
When you declare temp timestamp, temp is inited with the current timestamp |
| StrLib.usaDateFormat StrLib.eurDateFormat StrLib.jisDateFormat StrLib.isoDateFormat |
Constants.usaDateFormat Constants.eurDateFormat Constants.jisDateFormat Constants.isoDateFormat |
| StrLib.usaTimeFormat StrLib.eurTimeFormat StrLib.jisTimeFormat StrLib.isoTimeFormat |
Constants.usaTimeFormat Constants.eurTimeFormat Constants.jisTimeFormat Constants.isoTimeFormat |
| StrLib.db2StampFormat StrLib.odbcTimeStampFormat |
Constants.db2StampFormat Constants.odbcTimeStampFormat |
| DateTimeLib.dayOf(cTimeStamp) DateTimeLib.weekdayOf(cTimeStamp) DateTimeLib.monthOf(cTimeStamp) DateTimeLib.yearOf(cTimeStamp) DateTimeLib.dateOf(cTimeStamp) |
cTimeStamp.dayOf() cTimeStamp.weekdayOf() cTimeStamp.monthOf() cTimeStamp.yearOf() cTimeStamp.dateOf() |
| DateTimeLib.timeOf() DateTimeLib.timeValue() |
Not Supported |
| DateTimeLib.dateValueFromGregorian() DateTimeLib.dateValueFromJulian() |
DateTimeLib.dateFromGregorian() DateTimeLib.dateFromJulian() |
| XMLLib.convertToXML(eglType any) XMLLib.convertToXML(eglType any, document boolean) |
Use XMLLib.convertToXML(eglType any, document boolean) |
| ServiceLib.convertFromJSON(json string,eglType any) |
JsonLib.convertFromJSON(json string,eglType any) |
| ServiceLib.convertToJSON(eglType any) |
JsonLib.convertToJSON(eglType any) |
| Rational Business Developer | EDT |
| call host program
call local program Move statement |
Not supported right now |
| Rational Business Developer | EDT |
| matches | no longer an operator, have to use String matchesPattern() function instead |
| like | no longer an operator, have to use String isLike function instead |
| bitwise | operators support for int types only. Rational Business Developer supports SmallInt as well |
| Rational Business Developer | EDT |
| basicLibrary | no more basicLibrary |
| annotation on Library | no annotation is supported on library |
| RuntimeException |
no more RuntimeException, use AnyException |
| IndexOutOfBoundException |
InvalidIndexException |
| PGM includeReferencedFunctions=yes |
top level function are not supported |
| PGM allowUnqualifiedItemReferences = yes |
must fully qualify part names |
| XMLStructure = xmlStructurekind |
XMLValue {kind = xmlStructurekind. |
| FORMName |
|
| javaScriptName=xxx |
use externalName=xxx |
| d Dictionary{ordering=byInsertion} d Dictionary{ordering=byKey} |
d Dictionary = new Dictionary(true, OrderingKind.byInsertion) d Dictionary = new Dictionary(true, OrderingKind.byKey) The default for caseSensitive is false |
| aString string[0]{maxSize=10}; anInt int = aString.getMaxSize(); |
Not Supported(no more maxSize) |
EGL Rich UI MVC
| Rational Business Developer | EDT |
| validValues annotation | Not Supported |
A note on deployment descriptor files (*.egldd):
The model for these files is different in EDT so you cannot reuse deployment descriptors from Rational Business Developer. If you have a *.egldd file that's in the old format, and you want to "reset" it to be empty, you can open it with a text editor and replace it with the following:
<?xml version="1.0" encoding="UTF-8"?> <egl:deployment xmlns:egl= "http://www.eclipse.org/xmlns/edt/deployment/1.0" > </egl:deployment>
