本文整理了Java中groovy.lang.MetaClass.setAttribute()方法的一些代码示例，展示了MetaClass.setAttribute()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MetaClass.setAttribute()方法的具体详情如下：
包路径：groovy.lang.MetaClass
类名称：MetaClass
方法名：setAttribute

MetaClass.setAttribute介绍

[英]Sets the value of an attribute (field). This method is to support the Groovy runtime and not for general client API usage.
[中]设置属性（字段）的值。这种方法是为了支持Groovy运行时，而不是用于一般的客户端API。

代码示例

代码示例来源：origin: org.codehaus.groovy/groovy

public void setAttribute(Object object, String attribute, Object newValue) {
  delegate.setAttribute(object, attribute, newValue);
}

代码示例来源：origin: org.codehaus.groovy/groovy

public void setAttribute(Class sender, Object receiver, String messageName, Object messageValue, boolean useSuper, boolean fromInsideClass) {
  this.delegate.setAttribute(sender, receiver, messageName, messageValue, useSuper, fromInsideClass);
}

代码示例来源：origin: org.codehaus.groovy/groovy

public static void setAttribute(Object object, String attribute, Object newValue) {
  if (object == null) {
    object = NullObject.getNullObject();
  }
  if (object instanceof Class) {
    metaRegistry.getMetaClass((Class) object).setAttribute(object, attribute, newValue);
  } else if (object instanceof GroovyObject) {
    ((GroovyObject) object).getMetaClass().setAttribute(object, attribute, newValue);
  } else {
    metaRegistry.getMetaClass(object.getClass()).setAttribute(object, attribute, newValue);
  }
}

代码示例来源：origin: org.codehaus.groovy/groovy

public void setAttribute(Object object, String attribute, Object newValue) {
  final Object owner = getOwner();
  final MetaClass ownerMetaClass = getOwnerMetaClass(owner);
  ownerMetaClass.setAttribute(object, attribute, newValue);
}

代码示例来源：origin: org.codehaus.groovy/groovy

public void setAttribute(Class sender, Object receiver, String messageName, Object messageValue, boolean useSuper, boolean fromInsideClass) {
  final Object owner = getOwner();
  final MetaClass ownerMetaClass = getOwnerMetaClass(owner);
  ownerMetaClass.setAttribute(sender, owner, messageName, messageValue, useSuper, fromInsideClass);
}

代码示例来源：origin: org.codehaus.groovy/groovy

public static void setGroovyObjectField(Object messageArgument, Class senderClass, GroovyObject receiver, String messageName) throws Throwable {
  try {
    receiver.getMetaClass().setAttribute(receiver, messageName, messageArgument);
  } catch (GroovyRuntimeException gre) {
    throw unwrap(gre);
  }
}

代码示例来源：origin: org.codehaus.groovy/groovy

public static void setGroovyObjectFieldSafe(Object messageArgument, Class senderClass, GroovyObject receiver, String messageName) throws Throwable {
  if (receiver == null) return;
  try {
    receiver.getMetaClass().setAttribute(receiver, messageName, messageArgument);
  } catch (GroovyRuntimeException gre) {
    throw unwrap(gre);
  }
}

代码示例来源：origin: org.codehaus.groovy/groovy

public static void setFieldOnSuper(Object messageArgument, Class senderClass, Object receiver, String messageName) throws Throwable {
  try {
    if (receiver instanceof Class) {
      InvokerHelper.setAttribute(receiver, messageName, messageArgument);
    } else {
      MetaClass mc = ((GroovyObject) receiver).getMetaClass();
      mc.setAttribute(senderClass, receiver, messageName, messageArgument, true, true);
    }
  } catch (GroovyRuntimeException gre) {
    throw unwrap(gre);
  }
}

代码示例来源：origin: org.codehaus.groovy/groovy

@Override
public void setAttribute(Class sender, Object object, String attribute,
             Object newValue, boolean useSuper, boolean fromInsideClass) {
  if (object instanceof Class) {
    getStaticMetaClass().setAttribute(sender, object, attribute, newValue, useSuper, fromInsideClass);
  } else {
    if (!attributeInitDone) initAttributes();
    CachedField mfp = attributes.get(attribute);
    if (mfp == null) {
      CLOSURE_METACLASS.setAttribute(sender, object, attribute, newValue, useSuper, fromInsideClass);
    } else {
      mfp.setProperty(object, newValue);
    }
  }
}

代码示例来源：origin: org.codehaus.groovy/groovy

if (isStatic && object != theClass) {
  MetaClass mc = registry.getMetaClass((Class) object);
  mc.setAttribute(sender, object, attribute, newValue, useSuper, fromInsideClass);
  return;
