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).
the type to check
true if a binary representation created by this data
type can read as an instance * of valueType
Obtain a DeltaType by name or delta type.
Example:
// Get by name
var deltas = datatype.deltaType("binary");Example:
// Get by type
var deltas = datatype.deltaType(delta);the name, as returned by DeltaType.name
the delta type
The external type identifier.

Create a value of a compatible class from binary.

the offset to start reading from the provided buffer (default = 0)
the length of the data to read (default = input.length)
the value in the form of the specified type
Parse a value from binary.

Serialise a value to binary
the value to serialise. For primitive and JSON datatypes
the value can be undefined or null. In this case a
null value will be serialised.

Int64 data type.
Accessed via:
diffusion.datatypes.int64();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.
