UTF-8: Post-increments src and gets a value from the trie.

Sets the trie error value for an ill-formed byte sequence.

Unlike UCPTRIE_FAST_U16_NEXT() this UTF-8 macro does not provide the code point because it would be more work to do so and is often not needed. If the trie value differs from the error value, then the byte sequence is well-formed, and the code point can be assembled without revalidation.

Parameters

trie	(const UCPTrie *, in) the trie; must have type UCPTRIE_TYPE_FAST
dataAccess	UCPTRIE_16, UCPTRIE_32, or UCPTRIE_8 according to the trie’s value width
src	(const char *, in/out) the source text pointer
limit	(const char *, in) the limit pointer for the text (must not be NULL)
result	(out) variable for the trie lookup result

    } \
    (result) = dataAccess(trie, __index); \
} UPRV_BLOCK_MACRO_END

UTF-8: Pre-decrements src and gets a value from the trie.

Sets the trie error value for an ill-formed byte sequence.

Unlike UCPTRIE_FAST_U16_PREV() this UTF-8 macro does not provide the code point because it would be more work to do so and is often not needed. If the trie value differs from the error value, then the byte sequence is well-formed, and the code point can be assembled without revalidation.

Function Documentation

◆ ucptrie_close()

U_CAPI void ucptrie_close ( UCPTrie * trie )

Closes a trie and releases associated memory.

Parameters

trie the trie

Stable:: ICU 63

◆ ucptrie_get()

U_CAPI uint32_t ucptrie_get	(	const UCPTrie *	trie,
		UChar32	c
	)

Returns the value for a code point as stored in the trie, with range checking.

Returns the trie error value if c is not in the range 0..U+10FFFF.

Easier to use than UCPTRIE_FAST_GET() and similar macros but slower. Easier to use because, unlike the macros, this function works on all UCPTrie objects, for all types and value widths.

Parameters

trie	the trie
c	the code point

Returns: the trie value, or the trie error value if the code point is not in the range 0..U+10FFFF

Stable:: ICU 63

◆ ucptrie_getRange()

U_CAPI UChar32 ucptrie_getRange	(	const UCPTrie *	trie,
		UChar32	start,
		UCPMapRangeOption	option,
		uint32_t	surrogateValue,
		UCPMapValueFilter *	filter,
		const void *	context,
		uint32_t *	pValue
	)

Returns the last code point such that all those from start to there have the same value.

Can be used to efficiently iterate over all same-value ranges in a trie. (This is normally faster than iterating over code points and get()ting each value, but much slower than a data structure that stores ranges directly.)

If the UCPMapValueFilter function pointer is not NULL, then the value to be delivered is passed through that function, and the return value is the end of the range where all values are modified to the same actual value. The value is unchanged if that function pointer is NULL.

Example:

UChar32 start = 0, end;
uint32_t value;
while ((end = ucptrie_getRange(trie, start, UCPMAP_RANGE_NORMAL, 0,
                               NULL, NULL, &value)) >= 0) {
    // Work with the range start..end and its value.
    start = end + 1;
}

Parameters

trie	the trie
start	range start
option	defines whether surrogates are treated normally, or as having the surrogateValue; usually UCPMAP_RANGE_NORMAL
surrogateValue	value for surrogates; ignored if option==UCPMAP_RANGE_NORMAL
filter	a pointer to a function that may modify the trie data value, or NULL if the values from the trie are to be used unmodified
context	an opaque pointer that is passed on to the filter function
pValue	if not NULL, receives the value that every code point start..end has; may have been modified by filter(context, trie value) if that function pointer is not NULL

Returns: the range end code point, or -1 if start is not a valid code point

Stable:: ICU 63

◆ ucptrie_getType()

U_CAPI UCPTrieType ucptrie_getType ( const UCPTrie * trie )

Returns the trie type.

Parameters

trie the trie

Returns: the trie type

See also: ucptrie_openFromBinary; UCPTRIE_TYPE_ANY

◆ ucptrie_getValueWidth()

U_CAPI UCPTrieValueWidth ucptrie_getValueWidth ( const UCPTrie * trie )

Returns the number of bits in a trie data value.

Stable:: ICU 63

◆ ucptrie_openFromBinary()

		UCPTrieValueWidth	valueWidth,
		const void *	data,
		int32_t	length,
		int32_t *	pActualLength,
		UErrorCode *	pErrorCode
	)

Opens a trie from its binary form, stored in 32-bit-aligned memory.

Inverse of ucptrie_toBinary().

The memory must remain valid and unchanged as long as the trie is used. You must ucptrie_close() the trie once you are done using it.

Parameters

type	selects the trie type; results in an U_INVALID_FORMAT_ERROR if it does not match the binary data; use UCPTRIE_TYPE_ANY to accept any type
valueWidth	selects the number of bits in a data value; results in an U_INVALID_FORMAT_ERROR if it does not match the binary data; use UCPTRIE_VALUE_BITS_ANY to accept any data value width
data	a pointer to 32-bit-aligned memory containing the binary data of a UCPTrie
length	the number of bytes available at data; can be more than necessary
pActualLength	receives the actual number of bytes at data taken up by the trie data; can be NULL
pErrorCode	an in/out ICU UErrorCode

Returns: the trie

See also: umutablecptrie_open; umutablecptrie_buildImmutable; ucptrie_toBinary

Stable:: ICU 63

◆ ucptrie_toBinary()

U_CAPI int32_t ucptrie_toBinary	(	const UCPTrie *	trie,
		void *	data,
		int32_t	capacity,
		UErrorCode *	pErrorCode
	)

Writes a memory-mappable form of the trie into 32-bit aligned memory.

Inverse of ucptrie_openFromBinary().

Parameters

trie	the trie
data	a pointer to 32-bit-aligned memory to be filled with the trie data; can be NULL if capacity==0
capacity	the number of bytes available at data, or 0 for pure preflighting
pErrorCode	an in/out ICU UErrorCode; U_BUFFER_OVERFLOW_ERROR if the capacity is too small

Returns: the number of bytes written or (if buffer overflow) needed for the trie
