Package Summary Overview Summary

### class:UnionLayout [NONE]
All Superinterfaces: `GroupLayout`, `MemoryLayout` public sealed interface UnionLayout extends GroupLayout A group layout whose member layouts are laid out at the same starting offset. Since: 22 Implementation Requirements: Implementing classes are immutable, thread-safe and value-based.

### method:withName(java.lang.String) [NONE]
### withName UnionLayout withName (String name) Returns a memory layout with the same characteristics as this layout, but with the given name. Specified by: `withName` in interface `GroupLayout` Specified by: `withName` in interface `MemoryLayout` Parameters: `name` - the layout name. Returns: a memory layout with the same characteristics as this layout, but with the given name See Also: `MemoryLayout.name()`

### method:withoutName() [NONE]
### withoutName UnionLayout withoutName() Returns a memory layout with the same characteristics as this layout, but with no name. Specified by: `withoutName` in interface `GroupLayout` Specified by: `withoutName` in interface `MemoryLayout` Returns: a memory layout with the same characteristics as this layout, but with no name See Also: `MemoryLayout.name()`

### method:withByteAlignment(long) [NONE]
### withByteAlignment UnionLayout withByteAlignment (long byteAlignment) Returns a memory layout with the same characteristics as this layout, but with the given alignment constraint (in bytes). Specified by: `withByteAlignment` in interface `GroupLayout` Specified by: `withByteAlignment` in interface `MemoryLayout` Parameters: `byteAlignment` - the layout alignment constraint, expressed in bytes. Returns: a memory layout with the same characteristics as this layout, but with the given alignment constraint (in bytes) Throws: `IllegalArgumentException` - if `byteAlignment` is not a power of two. `IllegalArgumentException` - if `byteAlignment` is less than `M`, where `M` is the maximum alignment constraint in any of the member layouts associated with this group layout.
