 com.ibm.icu.impl.UCharacterProperty
| UCharacterProperty | | final public class UCharacterProperty (Code) | | Internal class used for Unicode character property database.
This classes store binary data read from uprops.icu.
It does not have the capability to parse the data into more high-level
information. It only returns bytes of information when required.
Due to the form most commonly used for retrieval, array of char is used
to store the binary data.
UCharacterPropertyDB also contains information on accessing indexes to
significant points in the binary data.
Responsibility for molding the binary data into more meaning form lies on
UCharacter.

| Method Summary | |
| public UnicodeSet | addPropertyStarts(UnicodeSet set)
| | public int | getAdditional(int codepoint, int column)
Gets the unicode additional properties. | | public VersionInfo | getAge(int codepoint)
Get the "age" of the code point.
The "age" is the Unicode version when the code point was first
designated (as a non-character or for Private Use) or assigned a
character.
This can be useful to avoid emitting code points to receiving
processes that do not accept newer characters.
The data is from the UCD file DerivedAge.txt.
This API does not check the validity of the codepoint.
Parameters:
codepoint - The code point. | | public static UCharacterProperty | getInstance()
Loads the property data and initialize the UCharacterProperty instance. | | final public static int | getMask(int type)
| | public int | getMaxValues(int column)
Get the the maximum values for some enum/int properties. | | final public int | getProperty(int ch)
Gets the property value at the index. | | public static int | getRawSupplementary(char lead, char trail)
| | public static int | getSignedValue(int prop)
| | final public int | getSource(int which)
| | public static int | getUnsignedValue(int prop)
| | public boolean | hasBinaryProperty(int codepoint, int property)
Check a binary Unicode property for a code point.
Unicode, especially in version 3.2, defines many more properties
than the original set in UnicodeData.txt.
This API is intended to reflect Unicode properties as defined in
the Unicode Character Database (UCD) and Unicode Technical Reports
(UTR).
For details about the properties see
http://www.unicode.org/.
For names of Unicode properties see the UCD file
PropertyAliases.txt.
This API does not check the validity of the codepoint.
Important: If ICU is built with UCD files from Unicode versions
below 3.2, then properties marked with "new" are not or
not fully available.

codepoint - Code point to test.

property - selector constant from com.ibm.icu.lang.UProperty,identifies which binary property to check. | | public static boolean | isRuleWhiteSpace(int c)

Note this is alittle different from CharTrie the index m_trieData_
is never negative.
