Method Detail

fromBinary

public static CodePointTrie.Fast fromBinary(CodePointTrie.ValueWidth valueWidth,
                                            ByteBuffer bytes)

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

Parameters:

valueWidth - selects the number of bits in a data value; this method throws an exception if the valueWidth does not match the binary data; use null to accept any data value width

bytes - a buffer containing the binary data of a CodePointTrie

Returns:

the trie

Status:

Stable ICU 63.

getType

public final CodePointTrie.Type getType()

Description copied from class: CodePointTrie

Returns the trie type.

Specified by:

getType in class CodePointTrie

Returns:

CodePointTrie.Type.FAST

Status:

Stable ICU 63.

bmpGet

public abstract 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.

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 abstract int suppGet(int c)

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

Parameters:

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

Returns:

The supplementary code point's trie value.

Status:

Stable ICU 63.

cpIndex

@Deprecated
protected final int cpIndex(int c)

Deprecated. This API is ICU internal only.

Specified by:

cpIndex in class CodePointTrie

Status:

Internal. This API is ICU internal only.

stringIterator

public final CodePointMap.StringIterator stringIterator(CharSequence s,
                                                        int sIndex)

Returns an iterator (not a java.util.Iterator) over code points of a string for fetching map values.

Overrides:

stringIterator in class CodePointMap

Parameters:

s - string to iterate over

sIndex - string index where the iteration will start

Returns:

the iterator

Status:

Stable ICU 63.
