Method Detail

processType

void processType(javax.lang.model.element.TypeElement autoOneOfType)

Description copied from class: AutoValueOrOneOfProcessor

Analyzes a single @AutoValue or @AutoOneOf class, and outputs the corresponding implementation class or classes.

Specified by:

processType in class AutoValueOrOneOfProcessor

Parameters:

autoOneOfType - the class with the @AutoValue or @AutoOneOf annotation.

mirrorForKindType

private javax.lang.model.type.DeclaredType mirrorForKindType(javax.lang.model.element.TypeElement autoOneOfType)

propertyToKindMap

private com.google.common.collect.ImmutableMap<java.lang.String,java.lang.String> propertyToKindMap(javax.lang.model.type.DeclaredType kindMirror,
                                                                                                          com.google.common.collect.ImmutableSet<java.lang.String> propertyNames)

transformName

private java.lang.String transformName(java.lang.String s)

findKindGetterOrAbort

private javax.lang.model.element.ExecutableElement findKindGetterOrAbort(javax.lang.model.element.TypeElement autoOneOfType,
                                                                         javax.lang.model.type.TypeMirror kindMirror,
                                                                         com.google.common.collect.ImmutableSet<javax.lang.model.element.ExecutableElement> abstractMethods)

validateMethods

private void validateMethods(javax.lang.model.element.TypeElement type,
                             com.google.common.collect.ImmutableSet<javax.lang.model.element.ExecutableElement> abstractMethods,
                             com.google.common.collect.ImmutableSet<javax.lang.model.element.ExecutableElement> propertyMethods,
                             javax.lang.model.element.ExecutableElement kindGetter)

defineVarsForType

private void defineVarsForType(javax.lang.model.element.TypeElement type,
                               AutoOneOfTemplateVars vars,
                               com.google.common.collect.ImmutableSet<javax.lang.model.element.ExecutableElement> propertyMethods,
                               javax.lang.model.element.ExecutableElement kindGetter)

nullableAnnotationForMethod

java.util.Optional<java.lang.String> nullableAnnotationForMethod(javax.lang.model.element.ExecutableElement propertyMethod)

Description copied from class: AutoValueOrOneOfProcessor

Returns the appropriate @Nullable annotation to put on the implementation of the given property method, and indicates whether the property is in fact nullable. The annotation in question is on the method, not its return type. If instead the return type is @Nullable, this method returns Optional.of(""), to indicate that the property is nullable but the method isn't. The @Nullable annotation will instead appear when the return type of the method is spelled out in the implementation.

Specified by:

nullableAnnotationForMethod in class AutoValueOrOneOfProcessor

sameType

private static boolean sameType(javax.lang.model.type.TypeMirror t1,
                                javax.lang.model.type.TypeMirror t2)
