Constructor Details

ScriptIter

public ScriptIter(MemorySegment address)

Create a ScriptIter proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ScriptIter

public ScriptIter(String text,
 int length)

Create a new PangoScriptIter, used to break a string of Unicode text into runs by Unicode script.

No copy is made of text, so the caller needs to make sure it remains valid until the iterator is freed with free().

Parameters:

text - a UTF-8 string

length - length of text, or -1 if text is nul-terminated

Since:

1.4

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ScriptIter class

Returns:

the GType

free

public void free()

Frees a PangoScriptIter.

Since:

1.4

getRange

public void getRange(@Nullable Out<String> start,
 @Nullable Out<String> end,
 @Nullable Out<Script> script)

Gets information about the range to which this ScriptIter currently points.

The range is the set of locations p where *start <= p < *end. (That is, it doesn't include the character stored at *end)

Note that while the type of the script argument is declared as PangoScript, as of Pango 1.18, this function simply returns GUnicodeScript values. Callers must be prepared to handle unknown values.

Parameters:

start - location to store start position of the range

end - location to store end position of the range

script - location to store script for range

Since:

1.4

next

public boolean next()

Advances a PangoScriptIter to the next range.

If this ScriptIter is already at the end, it is left unchanged and false is returned.

Returns:

true if this ScriptIter was successfully advanced

Since:

1.4
