Semantic and Syntactic Checking

CIM Object Manager performs syntactical and semantic checking. Syntactical checking refers to the ability to detect an error, such as a misplaced semicolon or a forgotten brace, in a line of code. Semantic checking refers to the ability to detect an error in the rules or logic of the program. The CIM Object Manager follows rules provided by the Common Information Model, and detects deviations from CIM rules in a WBEM application.

For example, CIM rules designate that only a key property can override another key property. Class A, which is assigned a key, cannot be overwritten by Class B because Class B is not assigned a key. In this case, CIM Object Manager returns a semantic error.

Class A        
\\Define Class A 
{     
[Key]     int a;   
}    
Class B:A     
 \\Class B extends A  
{  
[overrides ("a", key (false)]   int b;   
}
