S3Object

public S3Object()

方法详细资料

getObjectMetadata

public ObjectMetadata getObjectMetadata()

Gets the metadata stored by Amazon S3 for this object. The ObjectMetadata object includes any custom user metadata supplied by the caller when the object was uploaded, as well as HTTP metadata such as content length and content type.

返回:

The metadata stored by Amazon S3 for this object.

getObjectContent()

setObjectMetadata

public void setObjectMetadata(ObjectMetadata metadata)

Sets the object metadata for this object.

NOTE: This does not update the object metadata stored in Amazon S3, but only updates this object in local memory. To update an object's metadata in S3, use SCS#copyObject(CopyObjectRequest) to copy the object to a new (or the same location) and specify new object metadata then.

参数:

metadata - The new metadata to set for this object in memory.

getObjectContent

public S3ObjectInputStream getObjectContent()

Gets an input stream containing the contents of this object. Callers should close this input stream as soon as possible, because the object contents aren't buffered in memory and stream directly from Amazon S3.

返回:

An input stream containing the contents of this object.
