Class CollationRootElements

java.lang.Object
org.graalvm.shadowed.com.ibm.icu.impl.coll.CollationRootElements
public final class CollationRootElements extends Object
Container and access methods for collation elements and weights that occur in the root collator. Needed for finding boundaries for building a tailoring. This class takes and returns 16-bit secondary and tertiary weights.

  • Field Details

    • PRIMARY_SENTINEL

      public static final long PRIMARY_SENTINEL
      Higher than any root primary.

    • SEC_TER_DELTA_FLAG

      public static final int SEC_TER_DELTA_FLAG
      Flag in a root element, set if the element contains secondary invalid input: '&' tertiary weights, rather than a primary.

    • PRIMARY_STEP_MASK

      public static final int PRIMARY_STEP_MASK
      Mask for getting the primary range step value from a primary-range-end element.

    • IX_FIRST_TERTIARY_INDEX

      public static final int IX_FIRST_TERTIARY_INDEX
      Index of the first CE with a non-zero tertiary weight. Same as the start of the compact root elements table.

  • Method Details

    • getTertiaryBoundary

      public int getTertiaryBoundary()
      Returns the boundary between tertiary weights of primary/secondary CEs and those of tertiary CEs. This is the upper limit for tertiaries of primary/secondary CEs. This minus one is the lower limit for tertiaries of tertiary CEs.

    • getLastCommonSecondary

      public int getLastCommonSecondary()
      Returns the last common secondary weight. This is the lower limit for secondaries of primary CEs.

    • getSecondaryBoundary

      public int getSecondaryBoundary()
      Returns the boundary between secondary weights of primary CEs and those of secondary CEs. This is the upper limit for secondaries of primary CEs. This minus one is the lower limit for secondaries of secondary CEs.
