public class TryExpression
extends Expression

A GtkExpression that tries to evaluate each of its expressions until it succeeds.

If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well.

Constructor Details

TryExpression

public TryExpression(MemorySegment address)

Create a TryExpression instance for the provided memory address.

Parameters:

address - the memory address of the native object

TryExpression

public TryExpression(@Nullable Expression @Nullable [] expressions)

Creates a GtkExpression with an array of expressions.

When evaluated, the GtkTryExpression tries to evaluate each of its expressions until it succeeds. If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well.

The value type of the expressions in the array must match.

Parameters:

expressions - The array of expressions

Since:

4.22

Method Details

getType

public static @Nullable Type getType()

Get the GType of the TryExpression class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected TryExpression 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
