Description
Reads and returns an integer type number from the reader object's stream.
ReadInteger is a helper method used by other reader methods to read a tagged integer value at the current reader Position.
ReadInteger calls ReadValue to read the value-type indicator. If the retrieved value-type indicator is:
vaInt8-- ReadInteger calls Read to read the Int8 type integer value at the current reader Position and returns the obtained value as an Integer type value.vaInt16-- ReadInteger calls Read to read the Int16 type integer value at the current reader Position and returns the obtained value as an Integer type value.vaInt32-- ReadInteger calls Read to read the Int32 type integer value at the current reader Position and returns the obtained value as an Integer type value.- Otherwise, ReadInteger raises an EReadError exception.
ReadInteger advances the reader Position after the last byte it has read.
