Enum Constant Summary

Enum Constants

Enum Constant and Description
BMP Calculate the code range of a 16-bit (UTF-16 or compacted UTF-32) string that is already known to be in the BMP code range, so no UTF-16 surrogates are present.
LATIN1 Calculate the code range of a LATIN-1/ISO-8859-1 string.
UTF_16 Calculate the code range and codepoint length of a UTF-16 string.
UTF_32 Calculate the code range of a UTF-32 string.
UTF_8 Calculate the code range and codepoint length of a UTF-8 string.

Enum Constant Detail

LATIN1

public static final AMD64CalcStringAttributesOp.Op LATIN1

Calculate the code range of a LATIN-1/ISO-8859-1 string. The result is either CR_7BIT or CR_8BIT.

BMP

public static final AMD64CalcStringAttributesOp.Op BMP

Calculate the code range of a 16-bit (UTF-16 or compacted UTF-32) string that is already known to be in the BMP code range, so no UTF-16 surrogates are present. The result is either CR_7BIT, CR_8BIT, or CR_16BIT.

UTF_8

public static final AMD64CalcStringAttributesOp.Op UTF_8

Calculate the code range and codepoint length of a UTF-8 string. The result is a long value, where the upper 32 bit are the calculated codepoint length, and the lower 32 bit are the code range. The resulting code range is either CR_7BIT, CR_VALID_MULTIBYTE or CR_BROKEN_MULTIBYTE. If the string is broken (not encoded correctly), the resulting codepoint length is the number of non-continuation bytes in the string.

UTF_16

public static final AMD64CalcStringAttributesOp.Op UTF_16

Calculate the code range and codepoint length of a UTF-16 string. The result is a long value, where the upper 32 bit are the calculated codepoint length, and the lower 32 bit are the code range. The resulting code range can be any of the following: CR_7BIT, CR_8BIT, CR_16BIT, CR_VALID_MULTIBYTE, CR_BROKEN_MULTIBYTE. If the string is broken (not encoded correctly), the resulting codepoint length includes all invalid surrogate characters.

UTF_32

public static final AMD64CalcStringAttributesOp.Op UTF_32

Calculate the code range of a UTF-32 string. The result can be any of the following: CR_7BIT, CR_8BIT, CR_16BIT, CR_VALID_FIXED_WIDTH, CR_BROKEN_FIXED_WIDTH.
