Equality is determined by comparing the JSON representations of the objects. If `normalizeNumberTypes` is true, then all number types will be compared as strings (i.e. "1n" === "1" === 1). Else, they will be compared as their native types (i.e. 1n !== 1 !== "1"). #### Type Parameters ##### U `U` *extends* [`CustomType`](https://docs.bitbadges.io/sdk/reference/interfaces/custom-type)\<`U`\> #### Parameters ##### other [`CustomType`](https://docs.bitbadges.io/sdk/reference/interfaces/custom-type)\<`U`\> \| `null` \| `undefined` ##### normalizeNumberTypes? `boolean` #### Returns `boolean` #### Inherited from [`BaseNumberTypeClass`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class).[`equals`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class#equals) *** ### getNumberFieldNames() > **getNumberFieldNames**(): `string`[] Defined in: [packages/bitbadgesjs-sdk/src/api-indexer/docs-types/docs.ts:1616](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/api-indexer/docs-types/docs.ts#L1616) Internal helper method to convert the number fields of the object to a different NumberType equivalent. #### Returns `string`[] #### Overrides [`BaseNumberTypeClass`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class).[`getNumberFieldNames`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class#getnumberfieldnames) *** ### hasNumberFields() > **hasNumberFields**(): `boolean` Defined in: [packages/bitbadgesjs-sdk/src/common/base.ts:161](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/common/base.ts#L161) Checks if the object has number fields. #### Returns `boolean` #### Inherited from [`BaseNumberTypeClass`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class).[`hasNumberFields`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class#hasnumberfields) *** ### toJson() > **toJson**(): `JsonObject` Defined in: [packages/bitbadgesjs-sdk/src/common/base.ts:139](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/common/base.ts#L139) Converts the object to a JSON object with all primitive types. #### Returns `JsonObject` #### Inherited from [`BaseNumberTypeClass`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class).[`toJson`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class#tojson) *** ### toJsonString() > **toJsonString**(): `string` Defined in: [packages/bitbadgesjs-sdk/src/common/base.ts:143](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/common/base.ts#L143) Converts the object to a JSON string. #### Returns `string` #### Inherited from [`BaseNumberTypeClass`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class).[`toJsonString`](https://docs.bitbadges.io/sdk/reference/classes/base-number-type-class#tojsonstring)
