// Description:

// e32test\buffer\t_lex.cpp

// Overview:

// Test TLex and TLexMark classes.

// API Information:

// TLex, TLexMark.

// Details:

// - For Unicode, non Unicode and build independent variant of TLex class

// - Test that string-parsing methods are present.

// - Test the constructors with no parameter, by a string, with an empty TLex class, 

// non-empty TLex class is as expected.

// - Test assignment operator of TLex, by initializing with TLex reference, string, 

// TBuf reference and check it is as expected.

// - Check that Eos, Inc, Mark, Get, Peek, UnGet, SkipSpace, SkipSpaceAndMark, 

// SkipCharacters, TokenLength, MarkedToken methods are as expected.

// - Initialize Lex string, assign different values, Parse to extract signed, 

// unsigned integer of different lengths, using specified radix and verify 

// that the return value is KErrNone when a valid string is parsed, KErrGeneral 

// when invalid string is parsed, KErrOverflow when converted value is greater 

// than the limit. 

// - Refresh the contents with the system's locale settings, separate whole number from 

// it's fractional part, change locale settings then parse a 64-bit floating point 

// number and check that results are as expected.

// Platforms/Drives/Compatibility:

// All 

// Assumptions/Requirement/Pre-requisites:

// Failures and causes:

// Base Port information:
