Class VBlob

java.lang.Object

app.photofox.vipsffm.VBlob

public final class VBlob
extends Object

Represents a VipsBlob, boxed to avoid exposing its raw MemorySegment

Method Summary

Modifier and Type	Method	Description
ByteBuffer	asArenaScopedByteBuffer()	ByteBuffer representation of the data in this blob Mapped to native memory via DirectByteBuffer, hence does not make a copy, so the data has the same data lifetime as arena
ByteBuffer	asByteBuffer()	Deprecated, for removal: This API element is subject to removal in a future version. Replaced by asArenaScopedByteBuffer()
ByteBuffer	asClonedByteBuffer()	ByteBuffer representation of the data in this blob A full copy of the data is taken, so that its contents are not coupled to the scope of arena
long	byteSize()	Size of the data in this blob
MemorySegment	getUnsafeAddress()	Deprecated, for removal: This API element is subject to removal in a future version. Replaced by getUnsafeStructAddress()
MemorySegment	getUnsafeDataAddress()	Not recommended for use, use asByteBuffer() instead Gets the raw MemorySegment (C pointer) for the data in this blob Sliced to the length of the data, which isn't always null terminated
MemorySegment	getUnsafeStructAddress()	Gets the raw MemorySegment (C pointer) for this VipsBlob struct You might want the data address instead getUnsafeDataAddress() The memory address' lifetime is bound to the scope of the arena Usage of the memory address is strongly discouraged, but it is available if some functionality is missing and you need to use it with VipsHelper
