org.faktorips.fl.DefaultIdentifierResolver

All Implemented Interfaces:

IdentifierResolver<org.faktorips.codegen.JavaCodeFragment>

public class DefaultIdentifierResolver
extends Object
implements IdentifierResolver<org.faktorips.codegen.JavaCodeFragment>

A default implementation of IdentifierResolver that allows to register constant strings as identifiers together with a JavaCodeFragment and Datatype that are used to create a CompilationResult if the resolver is requested to compile the identifier. This implementation generates Java code.

Method Details

register

public void register(String identifier,
 org.faktorips.codegen.JavaCodeFragment fragment,
 org.faktorips.datatype.Datatype datatype)

Register the identifier.

compile

public CompilationResult<org.faktorips.codegen.JavaCodeFragment> compile(String identifier,
 ExprCompiler<org.faktorips.codegen.JavaCodeFragment> exprCompiler,
 Locale locale)

Description copied from interface: IdentifierResolver

Returns the compilation result for the indicated identifier.

If the given string is a valid identifier the compilation result must contain the source code that can be inserted in the expression's code along with the identifier's Datatype.

If the string is not a valid identifier the returned compilation result must contain an error message with the code UNDEFINED_IDENTIFIER.

Specified by:

compile in interface IdentifierResolver<org.faktorips.codegen.JavaCodeFragment>

Parameters:

identifier - The identifier to resolve.

exprCompiler - specialized ExprCompiler can down casted and used to ask for properties or services that are necessary to be able to resolve an identifier properly

locale - The locale used for locale dependent messages.
