Public Constructors
public IntTrie (InputStream inputStream, Trie.DataManipulate datamanipulate)
Creates a new Trie with the settings for the trie data.
Unserialize the 32-bit-aligned input stream and use the data for the trie.
Parameters
| inputStream | file input stream to a ICU data file, containing the trie |
|---|
Throws
| IOException | thrown when data reading fails |
|---|
Public Methods
public final int getCodePointValue (int ch)
Gets the value associated with the codepoint. If no value is associated with the codepoint, a default value will be returned.
Parameters
| ch | codepoint |
|---|
Returns
- offset to data
public final int getLeadValue (char ch)
Gets the value to the data which this lead surrogate character points to. Returned data may contain folding offset information for the next trailing surrogate character. This method does not guarantee correct results for trail surrogates.
Parameters
| ch | lead surrogate character |
|---|
Returns
- data value
public final int getTrailValue (int leadvalue, char trail)
Get a value from a folding offset (from the value of a lead surrogate) and a trail surrogate.
Parameters
| leadvalue | the value of a lead surrogate that contains the folding offset |
|---|---|
| trail | surrogate |
Returns
- trie data value associated with the trail character
Protected Methods
protected final int getInitialValue ()
Gets the default initial value
Returns
- 32 bit value
protected final int getSurrogateOffset (char lead, char trail)
Gets the offset to the data which the surrogate pair points to.
Parameters
| lead | lead surrogate |
|---|---|
| trail | trailing surrogate |
Returns
- offset to data
protected final int getValue (int index)
Gets the value at the argument index. For use internally in TrieIterator
Parameters
| index | value at index will be retrieved |
|---|
Returns
- 32 bit value

protected final void unserialize (InputStream inputStream)
Parses the input stream and stores its trie content into a index and data array
Parameters
| inputStream | data input stream containing trie data |
|---|
Throws
| IOException | thrown when data reading fails |
|---|
