Method Details

buildContextForMethod

@NonNull
public @NonNull ExpressionCompilationContext buildContextForMethod(@NonNull
 @NonNull EvaluatedExpressionReference expression,
 @NonNull
 @NonNull MethodElement methodElement)

Description copied from interface: ExpressionCompilationContextFactory

Builds expression evaluation context for method. Expression evaluation context for method allows referencing method parameter names in evaluated expressions.

Specified by:

buildContextForMethod in interface ExpressionCompilationContextFactory

Parameters:

expression - expression reference

methodElement - annotated method

Returns:

evaluation context for method

buildContext

@NonNull
public @NonNull ExpressionCompilationContext buildContext(EvaluatedExpressionReference expression,
 ClassElement thisElement)

Description copied from interface: ExpressionCompilationContextFactory

Builds expression evaluation context for expression reference.

Specified by:

buildContext in interface ExpressionCompilationContextFactory

Parameters:

expression - expression reference

Returns:

evaluation context for method

registerContextClass

public ExpressionCompilationContextFactory registerContextClass(ClassElement contextClass)

Description copied from interface: ExpressionCompilationContextFactory

Adds evaluated expression context class element to context loader at compilation time.

This method should be invoked from the TypeElementVisitor.start(VisitorContext) of a TypeElementVisitor

Specified by:

registerContextClass in interface ExpressionCompilationContextFactory

Parameters:

contextClass - context class element

Returns:

This context factory

reset

@Internal
public static void reset()

cleanup any stored contexts.
