Class UCharacterProperty

java.lang.Object
com.adobe.agl.impl.UCharacterProperty
public final class UCharacterProperty extends Object

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.

      public void setIndexData(CharTrie.FriendAgent friendagent)
      Java friends implementation

    • getProperty

      public final int getProperty(int ch)
      Gets the property value at the index. This is optimized. Note this is alittle different from CharTrie the index m_trieData_ is never negative.
      Parameters:
      ch - code point whose property value is to be retrieved
      Returns:
      property value of code point

    • getUnsignedValue

      public static int getUnsignedValue(int prop)
      Getting the unsigned numeric value of a character embedded in the property argument
      Parameters:
      prop - the character
      Returns:
      unsigned numberic value

    • getAdditional

      public int getAdditional(int codepoint, int column)
      Gets the unicode additional properties. C version getUnicodeProperties.
      Parameters:
      codepoint - codepoint whose additional properties is to be retrieved
      column -
      Returns:
      unicode properties

    • getAge

      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.
      Returns:
      the Unicode version number

    • getSource

      public final int getSource(int which)

    • getRawSupplementary

      public static int getRawSupplementary(char lead, char trail)
      Forms a supplementary code point from the argument character
      Note this is for internal use hence no checks for the validity of the surrogate characters are done
      Parameters:
      lead - lead surrogate character
      trail - trailing surrogate character
      Returns:
      code point of the supplementary character

    • getInstance

      public static UCharacterProperty getInstance()
      Loads the property data and initialize the UCharacterProperty instance.
      Throws:
      MissingResourceException - when data is missing or data has been corrupted

    • isRuleWhiteSpace

      public static boolean isRuleWhiteSpace(int c)
      Checks if the argument c is to be treated as a white space in ICU rules. Usually ICU rule white spaces are ignored unless quoted. Equivalent to test for Pattern_White_Space Unicode property. Stable set of characters, won't change. See UAX #31 Identifier and Pattern Syntax: http://www.unicode.org/reports/tr31/
      Parameters:
      c - codepoint to check
      Returns:
      true if c is a ICU white space

    • getMaxValues

      public int getMaxValues(int column)
      Get the the maximum values for some enum/int properties.
      Returns:
      maximum values for the integer properties.

    • getMask

      public static final int getMask(int type)
      Gets the type mask
      Parameters:
      type - character type
