dummymapper's Issues

GralhQL Action Options

Is your feature request related to a problem? Please describe.
Add GraphQL mapper options dialog support for:

All Queries as Non Null property
All as Queries by Default

Tests for core functionality

Some tests need to be implemented for all mappers, to check that all mapping options are correct for further regression testing.

Complex class with all possible fields used in test for each mapper.
Tests for ClassFactory
Tests for GenFactoryProvider
Tests for PsiJavaFileScanner

Raw Mapping classes are not provided

Describe the bug
Mapping config that is needed for GenRules is not provided correctly due to RawMarkers been skipped when constructing config

Inner class in collection \ map don't work

Describe the bug
Inner class scan when it is in collection or map doesn't work.

POJO example and expected behavior
Any inner class.

Support IntelliJ IDEA version 2023.3

From version IntelliJ IDEA 2023.3 DummyMapper is not compatible.

Please change for support new IDEA versions this very usefull plugin.

Optional objects

Does DummyMapper support nullable fields? In the README.md i dont see such example that would showcase an optional field that would be represented in schema as UNION with null hence the question.

Example how to create nullable field/record/array would be highly appreciated.

How to skip decoding the specific field

public class Subject {
    private String id;
    private LocalDateTime createTime;
}

{
  "id" : "cd491a3f-317d-4e4d-aaef-662a85d7c33e",
  "createTime" : {
    "nano" : 0,
    "year" : 2050,
    "monthValue" : 5,
    "dayOfMonth" : 6,
    "hour" : 11,
    "minute" : 45,
    "second" : 3,
    "dayOfYear" : 126,
    "dayOfWeek" : "FRIDAY",
    "month" : "MAY",
    "chronology" : {
      "calendarType" : "iso8601",
      "id" : "ISO"
    }
  }
}

the createTime field should not be decoded expectly.
it should looks like "createTime": 2020-12-18T14:57:00

can u support a annotation to specific field to skip it?
or append the LocalDateTime/LocalDate/LocalTime in mapping list which should be skipped.

Enums are not serialized to JSON

Describe the bug
A clear and concise description of what the bug is.
{
"type" : null
}

Java Class examples \ Screenshots
Java Class example (fields, annotations, method, type or what is applicable in a situation).

public class DummyEnum {

    public enum DummyType {
        SIMPLE,
        COMPLEX,
        UNKNOWN
    }

    @GenEnum
    private DummyType type;
}

Expected Behavior
Behavior you expected from mapper.

{
  "type" : "SIMPLE"
}

IDEA version
2020.2

Generating JSON for Collection or array of Enum doesn't work

Describe the bug
Generating JSON for Collection or array of Enum doesn't work as expected.

POJO example and expected behavior
class A{
public enum Type {
ONE,
TWO
}

private List types;
}

Generation such JSON doesn't work.
Expected behavior that generator will generate array \ collection of such elements

Empty Marker are provided for mapping

Describe the bug
Empty RawMarkers or Collection \ Map markers are in structure, so can not build any class due to absence of any fields in them

Improve issue windows with report button

Describe the solution you'd like
Error log with report should be like in IDEA or other plugins with separate window, report button, user-friendly, etc.

Like example IDEA exception report when internal plugin like Java crushes.

Map as JSON depth is only 2

Describe the bug
When mapping for JSON depth is only 2, this is due to misconfigured GenRules for mapping

Add README and GIFs

Is your feature request related to a problem? Please describe.
Add clear README with all functionality and add GIFs that show the functionality.

Add get JSON Array of objects

Is your feature request related to a problem? Please describe.
Add option to get not just single json mapped object but array of such objects

Is your feature request related to a problem? Please describe.
Check require restart plugin feature https://jetbrains.org/intellij/sdk/docs/basics/plugin_structure/dynamic_plugins.html
And set corresponding value if plugin require or otherwise

GenRule for array complex classes doesn't work

Describe the bug
GenRule is not setter for complex array fields.

POJO example and expected behavior
Any complex array field is not populated with values due to GenRule been not set for such fields.
Consider using global or auto for all complex classes.

Not compatible with IDEA2020.3

Describe the bug
Not compatible with IDEA2020.3

Inner class scan doesn't work

Scanner doesn't proper;y scan inner classes and they behave like enums (just list of strings)
Must be fixed before 1.0.0 release

Update to support IDEA 2021.2

Internal class name after mapping

Internal class name with suffix is exported when used mapper for AVRO \ JSON Schema, should renamed all classes back to their origin names

Handle AVRO mapping Object field exception

Is your feature request related to a problem? Please describe.
Improve handling of ""Any" type (usually for java.lang.Object) not supported: expectAnyFormat called with type [simple type, class java.lang.Object]" exception when POJO contains Object type field and it is mapped to AVRO.

Make a choice to mark all object as string by default or handle such case properly by displaing warning message and not error with trace.

Incompatible for IDEA 2022.1

Describe the bug
just build for 213.*, it's not incompatible in IDEA 2022.1

IDEA version
IDEA 2022.1 #IU-221.5080.210

Add GraphQL mapping support

Add support for GraphQL mapper option

AVRO schema real package

Describe the solution you'd like
A clear and concise description of what you want to happen.
When generating AVRO schema set real class package instead of library package name

Describe the bug
There is recursion when one RawMarker_1 -> RawMarker_2 -> RawMarker_1
Services like ClassFactory, Filters, GenRulesProvider are stackoverflowed if such behavior is happened

Avro schema mapper option

Is your feature request related to a problem? Please describe.
Add options to choose Apache Avro schema mapper instead of Jackson one.

Scan for Inner Enums in other classes don't work

Describe the bug
Scanning for Enums thats are inner classes of class other than they are scanned, doesn't work.

POJO example and expected behavior
class A {
public enum Type {
ONE
}
}

class B {
private A.Type type;
}

Add JSON Array window with options

Is your feature request related to a problem? Please describe.
Add window to map as JSON Array with option to input number of objects to generate

Array and not scanned by PsiJavaScanner

Describe the bug
Any array field is not scanned.

POJO example and expected behavior
class A{
private String[] array;
}

Field array should be scanner, but it doesn't.

Add caching for ClassFactory

Add caching for ClassFactory so classes won't be created and loaded again and again even if they were not modified since last build
