WriteIntegerToBuffer


Module: FoundationLite

Converts integer value into specified binary representation and writes it to a byte buffer.

Name Type Range Description
Input value inBuffer ByteBuffer Initial buffer to be expanded
Input value inOffset Integer* 0 - Write destination position
Input value inValue Integer Value to be written
Input value inFormat IntegerBinaryFormat Binary serialization format of integer data
Output value outBuffer ByteBuffer Resulting data

Description

This filter is intended for generating a raw binary data in the ByteBuffer by writing a properly serialized integer value into it.

Resulting ByteBuffer data on the outBuffer output is created by expanding data from buffer on the inBuffer input. Data is written starting at the position specified by the inOffset input (in bytes). When written data spans beyond the end of the input buffer the resulting buffer length is expanded (event when inOffset points beyond the end of the input buffer). When the inOffset input is set to Auto data is written at the end of the input buffer.

Integer value is converted into a binary representation according to the inFormat input value:

  • Signed_8Bit - signed two's complement 8-bit integer, 1 byte long.
  • Signed_16Bit_LittleEndian - signed two's complement 16-bit integer, 2 bytes long with little-endian byte order.
  • Signed_32Bit_LittleEndian - signed two's complement 32-bit integer, 4 bytes long with little-endian byte order.
  • Signed_64Bit_LittleEndian - signed two's complement 64-bit integer, 8 bytes long with little-endian byte order.
  • Unsigned_8Bit - unsigned 8-bit integer, 1 byte long.
  • Unsigned_16Bit_LittleEndian - unsigned 16-bit integer, 2 bytes long with little-endian byte order.
  • Unsigned_64Bit_LittleEndian - unsigned 64-bit integer, 8 bytes long with little-endian byte order.
  • Signed_16Bit_BigEndian - signed two's complement 16-bit integer, 2 bytes long with big-endian byte order.
  • Signed_32Bit_BigEndian - signed two's complement 32-bit integer, 4 bytes long with big-endian byte order.
  • Signed_64Bit_BigEndian - signed two's complement 64-bit integer, 8 bytes long with big-endian byte order.
  • Unsigned_16Bit_BigEndian - unsigned 16-bit integer, 2 bytes long with big-endian byte order.
  • Unsigned_32Bit_BigEndian - unsigned 32-bit integer, 4 bytes long with big-endian byte order.
  • Unsigned_64Bit_BigEndian - unsigned 64-bit integer, 8 bytes long with big-endian byte order.

Supported numeric range of stored value also depends on selected format:

  • Signed_8Bit: -128...127
  • Signed_16Bit_: -32768...32767
  • Signed_32Bit_: -2147483648...2147483647
  • Signed_64Bit_: -9223372036854775808...9223372036854775807 *
  • Unsigned_8Bit: 0...255
  • Unsigned_16Bit_: 0...65535
  • Unsigned_32Bit_: 0...4294967295 *
  • Unsigned_64Bit_: 0...18446744073709551615 *

 *) actual achievable range in the application is also limited by the Integer type

When a value from the inValue input (which is a signed 32-bit integer) cannot be stored in the selected format (it is out of its range) a DomainError is raised.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Input value is out of the valid range for specified integer binary format.
Value provided on inValue input cannot be cast to the type specified by the inFormat input.
DomainError Not supported integer binary format.
IoError Resulting byte buffer size is too large.

Complexity Level

This filter is available on Basic Complexity Level.

Filter Group

This filter is member of WriteToBuffer filter group.
