Stax2 API 4.2.2 · org.codehaus.stax2.typed.Base64Variants

Field Summary

Modifier and Type	Field and Description
public static final Base64Variant	MIME This variant is what most people would think of "the standard" Base64 encoding.
public static final Base64Variant	MIME_NO_LINEFEEDS Slightly non-standard modification of `MIME` which does not use linefeeds (max line length set to infinite).
public static final Base64Variant	MODIFIED_FOR_URL This non-standard variant is usually used when encoded data needs to be passed via URLs (such as part of GET request).
public static final Base64Variant	PEM This variant is the one that predates `MIME`: it is otherwise identical, except that it mandates shorter line length.
pack-priv static final String	STD_BASE64_ALPHABET

See wikipedia Base64 entry for details.

MIME_NO_LINEFEEDS	back to summary
public static final Base64Variant MIME_NO_LINEFEEDS Slightly non-standard modification of `MIME` which does not use linefeeds (max line length set to infinite). Useful when linefeeds wouldn't work well (possibly in attributes), or for minor space savings (save 1 linefeed per 76 data chars, ie. ~1.4% savings).

MODIFIED_FOR_URL back to summary

MODIFIED_FOR_URL	back to summary
public static final Base64Variant MODIFIED_FOR_URL This non-standard variant is usually used when encoded data needs to be passed via URLs (such as part of GET request). It differs from the base `MIME` variant in multiple ways. First, no padding is used: this also means that it generally can not be written in multiple separate but adjacent chunks (which would not be the usual use case in any case). Also, no linefeeds are used (max line length set to infinite). And finally, two characters (plus and slash) that would need quoting in URLs are replaced with more optimal alternatives (hyphen and underscore, respectively).
