//@PURPOSE: Provide an enumeration of the set of possible base64 ignore modes.
//
//@CLASSES:
//  bdlde::Base64IgnoreMode: namespace for an ignore mode 'enum'
//
//@SEE_ALSO: bdlde_base64decorderoptions, bdlde_base64decoder
//
//@DESCRIPTION: This component provides a namespace for the 'enum' type
// 'bdlde::Base64IgnoreMode::Enum', which enumerates the set of possible ignore
// modes for the 'bdlde::Base64Decoder'.
//
///Enumerators
///-----------
//..
//  Name                    Description
//  ---------------         ---------------------------------------------------
//  e_IGNORE_NONE           Any unrecognized character is an error
//  e_IGNORE_WHITESPACE     Any unrecognized character other than whitespace is
//                          an error
//  e_IGNORE_UNRECOGNIZED   No unrecognized character is an error
//..
//
///Usage
///-----
// In this section we show intended use of this component.
//
///Example 1: Basic Syntax
///- - - - - - - - - - - -
// The following snippets of code provide a simple illustration of
// 'bdlde::Base64IgnoreMode' usage.
//
// First, we create variable of type 'bdlde::Base64IgnoreMode::Enum' and
// initialize it with the enumerator values:
//..
//  const bdlde::Base64IgnoreMode::Enum none =
//                                bdlde::Base64IgnoreMode::e_IGNORE_NONE;
//  const bdlde::Base64IgnoreMode::Enum whitespace  =
//                                bdlde::Base64IgnoreMode::e_IGNORE_WHITESPACE;
//..
// Next, we store a pointer to their ASCII representation in variables of type
// 'const char *':
//..
//  const char *asciiNone       = bdlde::Base64IgnoreMode::toAscii(none);
//  const char *asciiWhitespace = bdlde::Base64IgnoreMode::toAscii(whitespace);
//  assert(0 == bsl::strcmp(asciiNone,       "IGNORE_NONE"));
//  assert(0 == bsl::strcmp(asciiWhitespace, "IGNORE_WHITESPACE"));
//..
//  Now, we stream some 'Enum's to 'ostream's:
//..
//  bsl::ostringstream ossNone, ossWhitespace;
//
//  ossNone       << none;
//  ossWhitespace << whitespace;
//..
// Finally, we observe the output of the streaming:
//..
//  assert(ossNone.str()       == "IGNORE_NONE");
//  assert(ossWhitespace.str() == "IGNORE_WHITESPACE");
//
//  assert(ossNone.str()       == asciiNone);
//  assert(ossWhitespace.str() == asciiWhitespace);
//..
