Variables.objectValue介绍

[英]Returns a builder to create a new ObjectValue that encapsulates the given value.
[中]返回一个生成器，以创建封装给定值的新ObjectValue。

代码示例

/**
 * Returns a builder to create a new {@link ObjectValue} that encapsulates
 * the given {@code value}.
 */
public static ObjectValueBuilder objectValue(Object value, boolean isTransient) {
 return (ObjectValueBuilder) objectValue(value).setTransient(isTransient);
}

代码示例来源：origin: camunda/camunda-bpm-platform

public TypedValue createValue(Object value, Map<String, Object> valueInfo) {
 ObjectValueBuilder builder = Variables.objectValue(value);
 if(valueInfo != null) {
  applyValueInfo(builder, valueInfo);
 }
 return builder.create();
}

public ObjectValue convertToTypedValue(UntypedValueImpl untypedValue) {
 // untyped values are always deserialized
