---|
Converts real value into specified binary representation and writes it to a byte buffer.
Name | Type | Range | Description | |
---|---|---|---|---|
inBuffer | ByteBuffer | Initial buffer to be expanded | ||
inOffset | Integer* | 0 - | Write destination position | |
inValue | Real | Value to be written | ||
inFormat | RealBinaryFormat | Binary serialization format of floating point data | ||
outBuffer | ByteBuffer | Resulting data |
Description
This filter is intended for generating a raw binary data in the ByteBuffer by writing a properly serialized floating point 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.
Real value is converted into a binary representation according to the inFormat input value:
- SinglePrecision_32Bit_LittleEndian - single precision floating point value, 4 bytes long with little-endian byte order.
- DoublePrecision_64Bit_LittleEndian - double precision floating point value, 8 bytes long with little-endian byte order.
- SinglePrecision_32Bit_BigEndian - single precision floating point value, 4 bytes long with big-endian byte order.
- DoublePrecision_64Bit_BigEndian - double precision floating point value, 8 bytes long with big-endian byte order.
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 | Not supported floating point binary format. |
IoError | Resulting buffer size is too large. |
Complexity Level
This filter is available on Basic Complexity Level.
