public JavaUnicodeEscaper(int below,
 int above,
 boolean between)

Constructs a JavaUnicodeEscaper for the specified range. This is the underlying method for the other constructors/builders. The below and above boundaries are inclusive when between is true and exclusive when it is false.

Parameters:

below - int value representing the lowest codepoint boundary

above - int value representing the highest codepoint boundary

between - whether to escape between the boundaries or outside them

Method Details

above

public static JavaUnicodeEscaper above(int codepoint)

Constructs a JavaUnicodeEscaper above the specified value (exclusive).

Parameters:

codepoint - above which to escape

Returns:

the newly created UnicodeEscaper instance

below

public static JavaUnicodeEscaper below(int codepoint)

Constructs a JavaUnicodeEscaper below the specified value (exclusive).

Parameters:

codepoint - below which to escape

Returns:

the newly created UnicodeEscaper instance

between

public static JavaUnicodeEscaper between(int codepointLow,
 int codepointHigh)

Constructs a JavaUnicodeEscaper between the specified values (inclusive).

Parameters:

codepointLow - above which to escape

codepointHigh - below which to escape

Returns:

the newly created UnicodeEscaper instance

outsideOf

public static JavaUnicodeEscaper outsideOf(int codepointLow,
 int codepointHigh)

Constructs a JavaUnicodeEscaper outside of the specified values (exclusive).

Parameters:

codepointLow - below which to escape

codepointHigh - above which to escape

Returns:

the newly created UnicodeEscaper instance
