方法详细资料

nullEscaper

public static Escaper nullEscaper()

Returns an Escaper that does no escaping, passing all character data through unchanged.

builder

public static Escapers.Builder builder()

Returns a builder for creating simple, fast escapers. A builder instance can be reused and each escaper that is created will be a snapshot of the current builder state. Builders are not thread safe.

The initial state of the builder is such that:

• There are no replacement mappings
• safeMin == Character.MIN_VALUE
• safeMax == Character.MAX_VALUE
• unsafeReplacement == null

For performance reasons escapers created by this builder are not Unicode aware and will not validate the well-formedness of their input.

computeReplacement

public static String computeReplacement(CharEscaper escaper,
                                        char c)

Returns a string that would replace the given character in the specified escaper, or null if no replacement should be made. This method is intended for use in tests through the EscaperAsserts class; production users of CharEscaper should limit themselves to its public interface.

参数:

c - the character to escape if necessary

返回:

the replacement string, or null if no escaping was needed

computeReplacement

public static String computeReplacement(UnicodeEscaper escaper,
                                        int cp)

Returns a string that would replace the given character in the specified escaper, or null if no replacement should be made. This method is intended for use in tests through the EscaperAsserts class; production users of UnicodeEscaper should limit themselves to its public interface.

参数:

cp - the Unicode code point to escape if necessary

返回:

the replacement string, or null if no escaping was needed
