java.lang.Object

javax.annotation.processing.AbstractProcessor

xdean.annotation.processor.toolkit.XAbstractProcessor

所有已实现的接口:

Processor, CommonUtil

直接已知子类:

CompileTest

public abstract class XAbstractProcessor
extends AbstractProcessor
implements CommonUtil

An more powerful abstract annotation processor designed to be a convenient superclass for most concrete annotation processors.

Differences with AbstractProcessor:

• Use SupportedAnnotation to define supported annotation by Class instead of String
• Assert methods for quick exit rather than check and return
• Convenient access to common utilities and log

XAbstractProcessor

public XAbstractProcessor()

方法详细资料

init

public void init(ProcessingEnvironment processingEnv)

指定者:

init 在接口中 Processor

覆盖:

init 在类中 AbstractProcessor

process

public final boolean process(Set<? extends TypeElement> annotations,
                             RoundEnvironment roundEnv)

Use processActual(Set, RoundEnvironment)

指定者:

process 在接口中 Processor

指定者:

process 在类中 AbstractProcessor

processActual

public abstract boolean processActual(Set<? extends TypeElement> annotations,
                                      RoundEnvironment roundEnv)
                               throws AssertException

Processes a set of annotation types on type elements originating from the prior round and returns whether or not these annotation types are claimed by this processor. If true is returned, the annotation types are claimed and subsequent processors will not be asked to process them; if false is returned, the annotation types are unclaimed and subsequent processors may be asked to process them. A processor may always return the same boolean value or may vary the result based on chosen criteria.

The input set will be empty if the processor supports "*" and the root elements have no annotations. A Processor must gracefully handle an empty set of annotations.

参数:

annotations - the annotation types requested to be processed

roundEnv - environment for information about the current and prior round

返回:

whether or not the set of annotation types are claimed by this processor

抛出:

AssertException - throw the AssertException to quit the process directly

另请参阅:

assertThat(boolean), handleAssert(Runnable)

handleAssert

protected void handleAssert(Runnable task)

Override this method to do something for AssertException.
The default behavior is log the message as error if present.

参数:

task - task who will throw AssertException

getSupportedAnnotationTypes

public Set<String> getSupportedAnnotationTypes()

If the processor class is annotated with SupportedAnnotation or SupportedAnnotationTypes, return an unmodifiable set with the same set of strings as the annotation. If the class is not so annotated, an empty set is returned.

指定者:

getSupportedAnnotationTypes 在接口中 Processor

覆盖:
