Class RollingCharBuffer

Acts like a forever growing char[] as you read characters into it from the provided reader, but internally it uses a circular buffer to only hold the characters that haven't been freed yet. This is like a PushbackReader, except you don't have to specify up-front the max size of the buffer, but you do have to periodically call FreeBefore(Int32).

Methods

FreeBefore(Int32)

Call this to notify us that no chars before this absolute position are needed anymore.

Declaration

public void FreeBefore(int pos)

Parameters

Type	Name	Description
System.Int32	pos

Get(Int32)

Absolute position read. NOTE: pos must not jump ahead by more than 1! Ie, it's OK to read arbitarily far back (just not prior to the last FreeBefore(Int32), but NOT ok to read arbitrarily far ahead. Returns -1 if you hit EOF.

Declaration

public int Get(int pos)

Parameters

Type	Name	Description
System.Int32	pos

Returns

Type	Description
System.Int32

Get(Int32, Int32)

Declaration

public char[] Get(int posStart, int length)

Parameters

Type	Name	Description
System.Int32	posStart
System.Int32	length

Returns

Type	Description
System.Char[]

Reset(TextReader)

Clear array and switch to new reader.

Declaration

public void Reset(TextReader reader)

Parameters
