RamStreamMBS.Constructor(InitialSize as Integer=0)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method RAMStream MBS Util Plugin 7.4 Yes Yes Yes Yes No
Function: Creates a new RAMStream.
Example:
dim r as RAMStreamMBS
r=new RAMStreamMBS(1000000)
r.write "Hello"
Notes:
To avoid memory fragmentation the memory grows in 32 KByte chunks.

The parameter you give is the size for the first allocation. So if you only need 2 KByte, you just pass 2048. If you don't know the size, you can pass 0 or a negative number to get the default initial size which is 32 KByte.

You can change the GrowSize property to use a different growing size.
Performance is better if resizing the memory buffer is minimized.

The stream can grow to around 2 GB.
On low memory, the initial resize will fail and length will be 0.
