All Implemented Interfaces:

TreeVisitor<Void,Void>

public class I18nFormatterVisitor
extends BaseTypeVisitor<I18nFormatterAnnotatedTypeFactory>

Whenever a method with I18nFormatFor annotation is invoked, it will perform the format string verification.

Method Details

visitMethodInvocation

public Void visitMethodInvocation(MethodInvocationTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Performs a method invocation check.

An invocation of a method, m, on the receiver, r is valid only if:

• passed arguments are subtypes of corresponding m parameters
• r is a subtype of m receiver type
• if m is generic, passed type arguments are subtypes of m type variables

Specified by:

visitMethodInvocation in interface TreeVisitor<Void,Void>

Overrides:

visitMethodInvocation in class BaseTypeVisitor<I18nFormatterAnnotatedTypeFactory>

commonAssignmentCheck

protected boolean commonAssignmentCheck(AnnotatedTypeMirror varType,
 AnnotatedTypeMirror valueType,
 Tree valueTree,
 @CompilerMessageKey String errorKey,
 Object... extraArgs)

Description copied from class: BaseTypeVisitor

Checks the validity of an assignment (or pseudo-assignment) from a value to a variable and emits an error message (through the compiler's messaging interface) if it is not valid.

Overrides:

commonAssignmentCheck in class BaseTypeVisitor<I18nFormatterAnnotatedTypeFactory>

Parameters:

varType - the annotated type of the variable

valueType - the annotated type of the value

valueTree - the location to use when reporting the error message

errorKey - the error message key to use if the check fails

extraArgs - arguments to the error message key, before "found" and "expected" types

Returns:

true if the check succeeds, false if an error message was issued
