public class Coverage
extends GObject

A PangoCoverage structure is a map from Unicode characters to Pango.CoverageLevel values.

It is often necessary in Pango to determine if a particular font can represent a particular character, and also how well it can represent that character. The PangoCoverage is a data structure that is used to represent that information. It is an opaque structure with no public fields.

Constructor Details

Coverage

public Coverage(MemorySegment address)

Create a Coverage proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Coverage

public Coverage()

Creates a new Coverage.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the Coverage class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected Coverage asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

fromBytes

@Deprecated
public static @Nullable Coverage fromBytes(@org.jspecify.annotations.Nullable byte @Nullable [] bytes)

Deprecated.

This returns null

Convert data generated from toBytes(org.javagi.base.Out<byte[]>) back to a PangoCoverage.

Parameters:

bytes - binary data representing a PangoCoverage

Returns:

a newly allocated PangoCoverage

copy

public Coverage copy()

Copy an existing PangoCoverage.

Returns:

the newly allocated PangoCoverage, with a reference count of one, which should be freed with unref().

get

public CoverageLevel get(int index)

Determine whether a particular index is covered by coverage.

Parameters:

index - the index to check

Returns:

the coverage level of this Coverage for character index.

max

@Deprecated
public void max(Coverage other)

Deprecated.

This function does nothing

Set the coverage for each index in this Coverage to be the max (better) value of the current coverage for the index and the coverage for the corresponding index in other.

Parameters:

other - another PangoCoverage

set

public void set(int index,
 CoverageLevel level)

Modify a particular index within this Coverage

Parameters:

index - the index to modify

level - the new level for index

toBytes

@Deprecated
public void toBytes(@Nullable Out<byte[]> bytes)

Deprecated.

This returns null

Convert a PangoCoverage structure into a flat binary format.

Parameters:

bytes - location to store result (must be freed with g_free())

unref

@Deprecated
public void unref()

Deprecated.

Use g_object_unref instead

Decrease the reference count on the PangoCoverage by one.

If the result is zero, free the coverage and all associated memory.

Overrides:

unref in class GObject

builder

public static Coverage.Builder<? extends Coverage.Builder> builder()

A Coverage.Builder object constructs a Coverage with the specified properties. Use the various set...() methods to set properties, and finish construction with Coverage.Builder.build().

Returns:

the builder object
