Generate more readable code for custom annotations #2895
Description
With PR #2792 we are generating custom annotations for the generated mappers.
The generated code currently looks like:
@CustomAnnotationWithParams(stringArray = "test", stringParam = "test", booleanArray = true, booleanParam = true, byteArray = 16, byteParam = 19, charArray = 'd', charParam = 'a', enumArray = AnnotateWithEnum.EXISTING, enumParam = AnnotateWithEnum.EXISTING, doubleArray = 0.3, doubleParam = 1.2, floatArray = 0.300000011920929f, floatParam = 1.2000000476837158f, intArray = 3, intParam = 1, longArray = 3L, longParam = 1L, shortArray = 3, shortParam = 1)and
@CustomAnnotationWithParams(stringArray = { "test1", "test2" }, booleanArray = { false, true }, byteArray = { 8, 31 }, charArray = { 'b', 'c' }, doubleArray = { 1.2, 3.4 }, floatArray = { 1.2000000476837158f, 3.4000000953674316f }, intArray = { 12, 34 }, longArray = { 12L, 34L }, shortArray = { 12, 34 }, classArray = { Mapper.class, CustomAnnotationWithParams.class }, stringParam = "required parameter")Everything is on one line.
I think that things would be more readable if we generate something like:
@CustomAnnotationWithParams(
stringArray = "test",
stringParam = "test",
booleanArray = true,
booleanParam = true,
byteArray = 16,
byteParam = 19,
charArray = 'd',
charParam = 'a',
enumArray = AnnotateWithEnum.EXISTING,
enumParam = AnnotateWithEnum.EXISTING,
doubleArray = 0.3,
doubleParam = 1.2,
floatArray = 0.300000011920929f,
floatParam = 1.2000000476837158f,
intArray = 3,
intParam = 1,
longArray = 3L,
longParam = 1L,
shortArray = 3,
shortParam = 1
)
and
@CustomAnnotationWithParams(
stringArray = { "test1", "test2" },
booleanArray = { false, true },
byteArray = { 8, 31 },
charArray = { 'b', 'c' },
doubleArray = { 1.2, 3.4 },
floatArray = { 1.2000000476837158f, 3.4000000953674316f },
intArray = { 12, 34 },
longArray = { 12L, 34L },
shortArray = { 12, 34 },
classArray = { Mapper.class, CustomAnnotationWithParams.class },
stringParam = "required parameter"
)
We need to be smarter in the code generation and do not always generate multiple lines.
An annotation with single parameter should look like:
@CustomAnnotationWithParams( stringArray = "test" )
We also need to see how to generate elements with multiple values.
