Variables

MAX_STRING_LENGTH_BEFORE_MD5

const MAX_STRING_LENGTH_BEFORE_MD5: 1024 = 1024

Defined in: data-mate/src/builder/type-coercion.ts:152

If we have a hash that is a long value we want to ensure that the value doesn't explode the memory since we may be using that value as a key. So when a string exceeds this specified length we can reduce its length to 35 characters by using md5

Functions

coerceToGeoBoundary()

coerceToGeoBoundary(input): GeoBoundary

Defined in: data-mate/src/builder/type-coercion.ts:107

Convert value to a GeoBoundary data type, a GeoBoundary is two GeoPoints, one representing the top left, the other representing the bottom right

Parameters

Parameter	Type
input	unknown

Returns

GeoBoundary

---

coerceToGeoPoint()

coerceToGeoPoint(input): GeoPoint

Defined in: data-mate/src/builder/type-coercion.ts:98

Convert value to a GeoPoint data type

Parameters

Parameter	Type
input	unknown

Returns

GeoPoint

---

coerceToNumberType()

coerceToNumberType(type): (input) => number | bigint

Defined in: data-mate/src/builder/type-coercion.ts:61

Parameters

Parameter	Type
type	FieldType

Returns

(input) => number | bigint

---

coerceToType()

coerceToType<T>(fieldConfig, childConfig?): CoerceFN<T>

Defined in: data-mate/src/builder/type-coercion.ts:23

Will return a function that will coerce the input values to the DataTypeFieldConfig provided. The parameter childConfig is only necessary with Tuple or Object field types

Type Parameters

Type Parameter	Default type
T	unknown

Parameters

Parameter	Type
fieldConfig	DataTypeFieldConfig
childConfig?	DataTypeFields

Returns

CoerceFN<T>

---

getHashCodeFrom()

getHashCodeFrom(value): string

Defined in: data-mate/src/builder/type-coercion.ts:159

Generate a unique hash code from a value, this is not a guarantee but it is close enough for doing groupBys and caching

Parameters

Parameter	Type
value	unknown

Returns

string

---

md5()

md5(value): string

Defined in: data-mate/src/builder/type-coercion.ts:165

Parameters

Parameter	Type
value	string | Buffer<ArrayBufferLike>

Returns

string
