Basic definitions for ICU, for both C and C++ APIs.
A mutable set of Unicode characters and multicharacter strings.
int8_t UBool
The ICU boolean type, a signed-byte integer.
Replaceable is an abstract base class representing a string of characters that supports the replaceme...
U_EXPORT UBool operator==(const StringPiece &x, const StringPiece &y)
Global operator == for StringPiece.
virtual UBool matchesIndexValue(uint8_t v) const =0
Returns true if this matcher will match a character c, where c & 0xFF == v, at offset,...
UProperty
Selection constants for Unicode properties.
An interface that defines both lookup protocol and parsing of symbolic names.
USetSpanCondition
Argument values for whether span() and similar functions continue while the current character is cont...
int32_t length(void) const
Return the length of the UnicodeString object.
static UClassID getStaticClassID()
ICU "poor man's RTTI", returns a UClassID for this class.
UnicodeString is a string class that stores Unicode characters directly and provides similar function...
int32_t UChar32
Define UChar32 as a type for single Unicode code points.
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
virtual UnicodeFilter * clone() const =0
Clones this object polymorphically.
uint32_t UCPMapValueFilter(const void *context, uint32_t value)
Callback function type: Modifies a map value.
UBool operator!=(const StringPiece &x, const StringPiece &y)
Global operator != for StringPiece.
struct UCPMap UCPMap
Abstract map from Unicode code points (U+0000..U+10FFFF) to integer values.
UMatchDegree
Constants returned by UnicodeMatcher::matches() indicating the degree of match.
virtual UBool contains(UChar32 c) const =0
Returns true for characters that are in the selected subset.
virtual UClassID getDynamicClassID(void) const =0
Returns a unique class ID polymorphically.
UnicodeFilter defines a protocol for selecting a subset of the full range (U+0000 to U+10FFFF) of Uni...
ParsePosition is a simple class used by Format and its subclasses to keep track of the current positi...
virtual UnicodeString & toPattern(UnicodeString &result, UBool escapeUnprintable=false) const =0
Returns a string representation of this matcher.
struct USet USet
USet is the C API type corresponding to C++ class UnicodeSet.
virtual UMatchDegree matches(const Replaceable &text, int32_t &offset, int32_t limit, UBool incremental)
Implement UnicodeMatcher API.
virtual void addMatchSetTo(UnicodeSet &toUnionTo) const =0
Union the set of all characters that may be matched by this object into the given set.
#define INITIAL_CAPACITY
The initial size of an array if it is unspecified.
