Jackson Core Source Code

Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

Jackson Core Source Code files are provided in the source packge (jackson-core-2.14.0-sources.jar). You can download it at Jackson Maven Website.

/**
 * Provides parsers that parse a {@code FloatingPointLiteral} from a
 * {@link java.lang.CharSequence}, {@code char} array, or {@code byte} array
 * ({@code str});.
 * <p>
 * Leading and trailing whitespace characters in {@code str} are ignored.
 * Whitespace is removed as if by the {@link java.lang.String#trim()} method;
 * that is, characters in the range [U+0000,U+0020].
 * <p>
 * The rest of {@code str} should constitute a  {@code FloatingPointLiteral} as described
 * by the lexical syntax rules shown below:
