Constructor Details

ClosureExpression

public ClosureExpression(MemorySegment address)

Create a ClosureExpression instance for the provided memory address.

Parameters:

address - the memory address of the native object

ClosureExpression

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

Get the GType of the ClosureExpression class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ClosureExpression asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class Expression

Returns:

the instance as if it were its parent type
