Is Object, a MemberDef or a Schema?

An object can be represented as a MemberDef or a Schema. Object as a MemberDef can be easily differentiated from Object as a schema using some rules expressed in the flowchart below.

When the first value is a datatype

If the first value in the object is a string and valid datatype such as number, string, object, bool, etc. then the object is a MemberDef. In the following example, the name is a MemberDef, because it defines the string value.

Example

name: { string, maxLen:100 } # MemberDef

When the object contains type

If the object has a type member then it is parsed as MemberDef. In the following example, testScore is a MemberDef, as it defines the type of object.

Example

dataType: { schema:{type:string, len:number}, type: object } # MemberDef

If the object contains schema

If the object contains schema then it is a MemberDef. In the following example, testData is a MemberDef, because it contains schema.

Example

testData: {  default: { }, schema: {a, b, c}  } # MemberDef

If the schema is set to an array in the object

If the schema inside the object is set to an array then it is a MemberDef. In the following example, subjectMarks is a MemberDef, because it contains the schema of an array.

Example

subjectMarks: {  default: { }, schema: [int]  } # MemberDef

If the object does not fall under any conditions given above

If the object does not fall under any of the above conditions then it is not a MemberDef. It is a schema of an object. The following example represents the object schema.

Example

name, age, address, isActive, remark # schema of an object
