Constructor Detail

CodepointSetGenerator

public CodepointSetGenerator(char[] chars)

All characters must be from BMP (no parts of surrogate pairs allowed).

CodepointSetGenerator

public CodepointSetGenerator(java.lang.String s)

Parse the given String and split into BMP and supplementary codepoints.

Method Detail

ofCodeUnitsLength

public java.lang.String ofCodeUnitsLength(java.util.Random r,
                                          int minCodeUnits,
                                          int maxCodeUnits)

Specified by:

ofCodeUnitsLength in class StringGenerator

minCodeUnits - Minimum number of code units (inclusive).

maxCodeUnits - Maximum number of code units (inclusive).

Returns:

Returns a string of variable length between minCodeUnits (inclusive) and maxCodeUnits (inclusive) length. Code units are essentially an equivalent of char type, see String class for explanation.

ofCodePointsLength

public java.lang.String ofCodePointsLength(java.util.Random r,
                                           int minCodePoints,
                                           int maxCodePoints)

Specified by:

ofCodePointsLength in class StringGenerator

minCodePoints - Minimum number of code points (inclusive).

maxCodePoints - Maximum number of code points (inclusive).

Returns:

Returns a string of variable length between minCodePoints (inclusive) and maxCodePoints (inclusive) length. Code points are full unicodeGenerator codepoints or an equivalent of int type, see String class for explanation. The returned String.length() may exceed maxCodeUnits because certain code points may be encoded as surrogate pairs.

isOdd

private boolean isOdd(int v)

Is a given number odd?

concat

private int[] concat(int[]... arrays)

isSurrogate

private boolean isSurrogate(char chr)
