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.

time

Before 0.8.1 M2: replaced with timestamp 
After 0.8.1 M2: time is now available in EDT

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

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>
