Using the sample provided I was able to retrieve the properties, but what I
wanted is to be able to put values in it.
Here is a sample code:
MetaStructureClass employee = namespace.getMetaClass( "employee",
true );
MetaStructureProperty firstName = namespace.getMetaProperty(
"firstName", true );
firstName.setRange( new DatatypeClassRange( String.class ) );
MetaStructureProperty lastName = namespace.getMetaProperty(
"lastName", true );
lastName.setRange( new DatatypeClassRange( String.class ) );
MetaStructureProperty middleName = namespace.getMetaProperty(
"middleName", true );
middleName.setRange( new DatatypeClassRange( String.class ) );
MetaStructureProperty age = namespace.getMetaProperty( "age", true
);
age.setRange( new DatatypeClassRange( Integer.class ) );
employee.getDirectProperties().add( firstName );
employee.getDirectProperties().add( lastName );
employee.getDirectProperties().add( middleName );
employee.getDirectProperties().add( age );
My objective is to put/add property values to the ff as in:
firstName = "John";
lastName = "Doe";
middleName = "Smith";
age = 25;
That's what I understand using meta structure, but would that be possible?
If yes can you please show me how?
Thanks.
