Method Details

doResolveType

protected org.objectweb.asm.Type doResolveType(ExpressionVisitorContext ctx)

Description copied from class: ExpressionNode

Resolves expression AST node type.

Specified by:

doResolveType in class ExpressionNode

Parameters:

ctx - expression compilation context

Returns:

resolved type

doResolveClassElement

protected ClassElement doResolveClassElement(ExpressionVisitorContext ctx)

Description copied from class: ExpressionNode

Resolves the class element for this node.

Overrides:

doResolveClassElement in class ExpressionNode

Parameters:

ctx - The expression compilation context

Returns:

The resolved type

resolveUsedMethod

@NonNull
protected abstract @NonNull io.micronaut.expressions.parser.ast.access.CandidateMethod resolveUsedMethod(ExpressionVisitorContext ctx)

Resolves single CandidateMethod used by this AST node.

Parameters:

ctx - Expression compilation context

Returns:

AST node candidate method

Throws:

ExpressionCompilationException - if no candidate method can be found or if there is more than one candidate method.

toCandidateMethod

protected io.micronaut.expressions.parser.ast.access.CandidateMethod toCandidateMethod(ExpressionVisitorContext ctx,
 MethodElement methodElement,
 List<org.objectweb.asm.Type> argumentTypes)

Parameters:

ctx - expression compilation context

methodElement - method element

argumentTypes - types of arguments used for method invocation in expression

Returns:

candidate method

prepareVarargsArguments

protected List<ExpressionNode> prepareVarargsArguments()

This method wraps original method arguments into array for methods using varargs.

Returns:

list of arguments, including varargs arguments wrapped in array

resolveArgumentTypes

protected List<org.objectweb.asm.Type> resolveArgumentTypes(ExpressionVisitorContext ctx)

Compiles method arguments.

Parameters:

ctx - expression evaluation context

stringifyArguments

protected String stringifyArguments(ExpressionVisitorContext ctx)

Prepares arguments string for logging purposes.

Parameters:

ctx - expression compilation context

Returns:

arguments string
