Method Details

fromBinary

public static CodePointTrie.Fast16 fromBinary(ByteBuffer bytes)

Creates a trie from its binary form. Same as CodePointTrie.fromBinary(Type, ValueWidth, ByteBuffer) with CodePointTrie.Type.FAST and CodePointTrie.ValueWidth.BITS_16.

Parameters:

bytes - a buffer containing the binary data of a CodePointTrie

Returns:

the trie

Status:

Stable ICU 63.

get

public final int get(int c)

Returns the value for a code point as stored in the map, with range checking. Returns an implementation-defined error value if c is not in the range 0..U+10FFFF.

Overrides:

get in class CodePointTrie

Parameters:

c - the code point

Returns:

the map value, or an implementation-defined error value if the code point is not in the range 0..U+10FFFF

Status:

Stable ICU 63.

bmpGet

public final int bmpGet(int c)

Returns a trie value for a BMP code point (U+0000..U+FFFF), without range checking. Can be used to look up a value for a UTF-16 code unit if other parts of the string processing check for surrogates.

Specified by:

bmpGet in class CodePointTrie.Fast

Parameters:

c - the input code point, must be U+0000..U+FFFF

Returns:

The BMP code point's trie value.

Status:

Stable ICU 63.

suppGet

public final int suppGet(int c)

Returns a trie value for a supplementary code point (U+10000..U+10FFFF), without range checking.

Specified by:

suppGet in class CodePointTrie.Fast

Parameters:

c - the input code point, must be U+10000..U+10FFFF

Returns:

The supplementary code point's trie value.

Status:

Stable ICU 63.
