AnsiStringBase::ByteType Method

Indicates the kind of byte that occupies a specified position in the System::AnsiStringBase.

Pascal

function ByteType(index: Integer): TStringMbcsByteType;

C++

__fastcall TStringMbcsByteType ByteType(int index) const;

Description

System::AnsiStringBase::ByteType indicates what kind of byte exists at the byte indicated by index (counting from 1) in the System::AnsiStringBase. These are the possible return values.

Constant	Meaning
mbSingleByte	Single byte character.
mbLeadByte	Lead byte of a multi-byte character.
mbTrailByte	Trailing byte of a multi-byte character.

Some locales, including all Western locales, do not use multi-byte characters. Under those locales, System::AnsiStringBase::ByteType always returns mbSingleByte.

Note: No checking is done to ensure that Index is less than the length of S. It is the caller's responsibility to ensure that Index is not out of bounds.
