Class CollationData

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.coll.CollationData

public final class CollationData
extends Object

Collation data container. Immutable data created by a CollationDataBuilder, or loaded from a file, or deserialized from API-provided binary data. Includes data for the collation base (root/default), aliased if this is not the base.

Field Summary

Field Detail

base

public CollationData base

Base collation data, or null if this data itself is a base.

nfcImpl

public Normalizer2Impl nfcImpl

compressibleBytes

public boolean[] compressibleBytes

256 flags for which primary-weight lead bytes are compressible.

fastLatinTable

public char[] fastLatinTable

Fast Latin table for common-Latin-text string comparisons. Data structure see class CollationFastLatin.

rootElements

public long[] rootElements

Collation elements in the root collator. Used by the CollationRootElements class. The data structure is described there. null in a tailoring.

Method Detail

getCE32

public int getCE32(int c)

isUnsafeBackward

public boolean isUnsafeBackward(int c,
                                boolean numeric)

isCompressibleLeadByte

public boolean isCompressibleLeadByte(int b)

isCompressiblePrimary

public boolean isCompressiblePrimary(long p)

getLastPrimaryForGroup

public long getLastPrimaryForGroup(int script)

Returns the last primary for the script's reordering group.

Returns:

the last primary of the group (not an actual root collator primary weight), or 0 if the script is unknown

getGroupForPrimary

public int getGroupForPrimary(long p)

Finds the reordering group which contains the primary weight.

Returns:

the first script of the group, or -1 if the weight is beyond the last group

getEquivalentScripts

public int[] getEquivalentScripts(int script)
