我正在使用JSONIX来编码和解码XML文件。到目前为止,它运行良好。我缺少的是获得默认值和限制(如minOccours和maxOccours-Values)的可能性。 JSONIX可以通过某种方式实现吗?
这些属性:
<xsd:sequence>
<xsd:element name="inflowMin" type="framework:flowType" minOccurs="0" maxOccurs="1"/>
<xsd:element name="inflowMax" type="framework:flowType" minOccurs="0" maxOccurs="1"/>
<xsd:element name="unitOfFlowControl" type="framework:flowUnit" minOccurs="0" maxOccurs="1"/>
</xsd:sequence>
<xsd:attribute name="waterCosts" type="xsd:double" default="0.0"/>
<xsd:attribute name="controllable" type="xsd:boolean" default="0"/>
<xsd:attribute name="scalingOfControl" type="xsd:double" default="1.0" />
得到:
propertyInfos: [{
type: 'element',
name: 'inflowMin',
elementName: 'inflowMin',
typeInfo: ...
}, {
type: 'element',
name: 'inflowMax',
elementName: 'inflowMax',
typeInfo: ...
}, {
type: 'element',
name: 'unitOfFlowControl',
elementName: 'unitOfFlowControl',
typeInfo: 'String'
}, {
name: 'waterCosts',
typeInfo: 'Double',
attributeName: 'waterCosts',
type: 'attribute'
}, {
name: 'controllable',
typeInfo: 'Boolean',
attributeName: 'controllable',
type: 'attribute'
}, {
name: 'scalingOfControl',
typeInfo: 'Double',
attributeName: 'scalingOfControl',
type: 'attribute'
}]
}
谢谢!
最佳答案
您要求的功能现在已在Jsonix 2.3.2和Jsonix Schema Compiler 2.3.7中实现。
现在,Jsonix Schema Compiler会在生成的映射和JSON模式中生成required
,minOccurs
和maxOccurs
。
这是在映射中的外观:
{
localName: 'Items',
propertyInfos: [{
name: 'item',
minOccurs: 0,
maxOccurs: 100,
collection: true,
elementName: {
localPart: 'item'
},
typeInfo: '.Items.Item'
}]
}
并在JSON模式中:
"Items":{
"type":"object",
"title":"Items",
"properties":{
"item":{
"title":"item",
"allOf":[
{
"type":"array",
"items":{
"$ref":"#/definitions/Items.Item"
},
"maxItems":100,
"minItems":0
}
],
"propertyType":"element",
"elementName":{
"localPart":"item",
"namespaceURI":""
}
}
},
"typeType":"classInfo",
"typeName":{
"localPart":"Items",
"namespaceURI":""
},
"propertiesOrder":[
"item"
]
}
您可以从Jsonix上下文访问此元数据,如下所示:
var context = new Jsonix.Context([ PO ]);
var itemsClassInfo = context.getTypeInfoByName("PO.Items");
var itemPropertyInfo = itemsClassInfo.getPropertyInfoByName("item");
test.equal(false, itemPropertyInfo.required);
test.equal(0, itemPropertyInfo.minOccurs);
test.equal(100, itemPropertyInfo.maxOccurs);
test.done();
