BigEndianWriter

Utility struct for writing to a pointer in Big Endian.

BigEndianWriter is a struct providing methods for writing various types of data to a memory location, with the data being written in Big Endian byte order. This includes writing integers, floating point values, and arrays of bytes, either advancing the pointer after each write or writing at a specific offset without advancing the pointer.

Properties

Ptr

public byte* Ptr;

Current pointer being written to.

Constructors

BigEndianWriter

public BigEndianWriter(byte* ptr)

Creates a simple wrapper around a pointer that writes in Big Endian. ptr is the pointer to the item behind the writer.

Methods

Write

public void Write(sbyte value)
public void Write(byte value)
public void Write(short value)
public void Write(ushort value)
public void Write(int value)
public void Write(uint value)
public void Write(long value)
public void Write(ulong value)
public void Write(float value)
public void Write(double value)
public void Write(Span<byte> data)

Writes a value to the current pointer and advances the pointer. Overloads exist for various data types including sbyte, byte, short, ushort, int, uint, long, ulong, float, double, and Span<byte>.

WriteAtOffset

public void WriteAtOffset(sbyte value, int offset)
public void WriteAtOffset(byte value, int offset)
public void WriteAtOffset(short value, int offset)
public void WriteAtOffset(ushort value, int offset)
public void WriteAtOffset(int value, int offset)
public void WriteAtOffset(uint value, int offset)
public void WriteAtOffset(long value, int offset)
public void WriteAtOffset(ulong value, int offset)
public void WriteAtOffset(float value, int offset)
public void WriteAtOffset(double value, int offset)

Writes a value to the specified offset without advancing the pointer. Overloads exist for various data types including sbyte, byte, short, ushort, int, uint, long, ulong, float, double.

Seek

public void Seek(int offset)

Advances the stream by a specified number of bytes. offset is the number of bytes to advance by.

About the Offset Methods

The BigEndianWriter struct provides several methods that operate on a specific offset without advancing the pointer.

While these methods do not significantly reduce the instruction count, they offer some minor performance advantages, you can read more about this in About Section

Usage

Example usage of the BigEndianWriter struct:

var writer = new BigEndianWriter(ptr);

writer.Write((int)12345);  // Write an int
writer.Write((byte)65);    // Write a byte
writer.WriteAtOffset((long)9876543210, 5);  // Write a long at offset 5 from current pointer
