Caps is a light, simple serialization library, support data types:

• int32
• uint32
• int64
• uint64
• string
• float
• double

Node-Caps is a wrapper of Caps using N-API

writeInt32(num) write int32 value into this Caps object

• num int32, 4 bytes

writeUInt32(num) write uint32 value into this Caps object

• num uint32, 4 bytes

writeInt64(num) write int64 value into this Caps object

• num int64, 8 bytes

writeUInt64(num) write uint64 value into this Caps object

• num uint64, 8 bytes

writeFloat(num) write float value into this Caps object

• num float, 4 bytes

writeDouble(num) write int32 value into this Caps object

• num double number, 8 bytes

writeCaps(capsObj) write another Caps object into this Caps

• capsObj Caps object

readInt32() read out a int32 value

• return int32 value

readUInt32() read out a uint32 value

• return uint32 value

readInt64() read out a int64 value

• return int64 value

readUInt64() read out a uint64 value

• return uint64 value

readFloat() read out a float value

• return float value

readDouble() read out a double value

• return double value

readCaps(capsObj) read out a Caps object

• return Caps object

serialize(byteOrder) serialize this Caps object into UInt8Array byteOrder Caps.NetworkByteOrder/Caps.NBO, Caps.HostByteOrder/Caps.HBO

serializeForCapsObj(byteOrder) serialize this Caps object into another one byteOrder Caps.NetworkByteOrder/Caps.NBO, Caps.HostByteOrder/Caps.HBO

deserialize(uint8Array) deserialize from UInt8Array uint8Array the buff deserialize to Caps object

deserializeForCapsObj(capsObj) deserialize from another Caps object capsObj the Caps object contain another Caps
