Class UCharacterProperty

java.lang.Object
org.graalvm.shadowed.com.ibm.icu.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.

  • Method Details

    • getProperty

      public final int getProperty(int ch)
      Gets the main property value for code point ch.
      Parameters:
      ch - code point whose property value is to be retrieved
      Returns:
      property value of code point

    • getAdditional

      public int getAdditional(int codepoint, int column)
      Gets the unicode additional properties. Java version of C u_getUnicodeProperties().
      Parameters:
      codepoint - codepoint whose additional properties is to be retrieved
      column - The column index.
      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

    • getMaxValues

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

    • getMask

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

    • getEuropeanDigit

      public static int getEuropeanDigit(int ch)
      Returns the digit values of characters like 'A' - 'Z', normal, half-width and full-width. This method assumes that the other digit characters are checked by the calling method.
      Parameters:
      ch - character to test
      Returns:
      -1 if ch is not a character of the form 'A' - 'Z', otherwise its corresponding digit will be returned.
