TReader.ReadInt64 Method

Reads an 64-bit integer from the reader object's stream and returns its value.

function ReadInt64: Int64;
__fastcall Int64 ReadInt64();

ReadInt64 is a helper method used by other reader methods to read a tagged 64-bit integer value at the current reader Position. ReadInt64 first checks the value type (TValueType) by calling the ReadValue method. If the item is a vaInt64, ReadInt64 calls Read and returns the integer value. Otherwise it calls ReadInteger, in case the value was saved in another integer format.
