The Int64 data type value class
Test whether this data type is compatible with valueType
. Compatibility
with a valueType
means than any valid binary representation of a
value
can be read as an
instance of valueType
.
Every data type should be compatible with the following:
Value Type
– the class corresponding to the data type's value
type.For a data type with a value type of X
, readAs(X, buffer)
is
equivalent to readValue(buffer)
.

type can read as an instance * of valueType
Obtain a DeltaType by name or delta type.

// Get by name
var deltas = datatype.deltaType("binary");
Example:
// Get by type
var deltas = datatype.deltaType(delta);

Provides a data type implementation which supports 64-bit signed integer values. The Int64 value is serialized in CBOR-format binary.
This data type supports null Int64 values.
