Constructor Details

ConstantExpression

public ConstantExpression(MemorySegment address)

Create a ConstantExpression proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ConstantExpression

public ConstantExpression(Type valueType,
 Object... varargs)

Creates a GtkExpression that evaluates to the object given by the arguments.

Parameters:

valueType - The type of the object

varargs - arguments to create the object from

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ConstantExpression class

Returns:

the GType

asParent

protected ConstantExpression 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 Expression

forValue

public static ConstantExpression forValue(Value value)

Creates an expression that always evaluates to the given value.

Parameters:

value - a GValue

Returns:

a new GtkExpression

getValue

public Value getValue()

Gets the value that a constant expression evaluates to.

Returns:

the value
