Constructor Details

ClosureExpression

public ClosureExpression(MemorySegment address)

Create a ClosureExpression proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ClosureExpression

public ClosureExpression(Type valueType,
 Closure closure,
 @Nullable
 @Nullable Expression[] params)

Creates a GtkExpression that calls closure when it is evaluated.

closure is called with the this object and the results of evaluating the params expressions.

Parameters:

valueType - the type of the value that this expression evaluates to

closure - closure to call when evaluating this expression. If closure is floating, it is adopted

params - expressions for each parameter

Method Details

getType

public static Type getType()

Get the GType of the ClosureExpression class

Returns:

the GType

asParent

protected ClosureExpression 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
