Reads and optionally removes a specific byte value from the internal storage for the buffer.
function ExtractToByte( const AIndex: Integer ): Byte;
Byte - Value extracted from the internal storage for the buffer.
ExtractToByte is a Byte function used to read and remove a specified byte value from the internal storage for the buffer.
AIndex is the zero-based offset of the byte value to extract from the internal storage for the buffer. AIndex normally contains a value in the range 0 (zero) to Size-1. When AIndex contains 0 or a positive value, the content in the buffer is not altered by the Extract operation.
Using a negative value in AIndex indicates that data is being accessed sequentially and calls Remove to adjust the current buffer position and the space allocated for the buffer.
ExtractToByte returns a single byte value using the Encoding for the buffer.
Use one of the other Extract methods to read a specific data type from the internal storage for the buffer:
Use IndexOf to find the position in the buffer where a specific sequence of byte values is located.
Use PeekByte to access a specific byte value by its' position in the buffer.
