COSObject

public COSObject()

方法详细资料

getObjectMetadata

public ObjectMetadata getObjectMetadata()

Gets the metadata stored by Qcloud COS 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 Qcloud COS 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 Qcloud COS, but only updates this object in local memory. To update an object's metadata in COS, use COS#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 COSObjectInputStream getObjectContent()

Gets the input stream containing the contents of this object.

Note: The method is a simple getter and does not actually create a stream. If you retrieve an COSObject, you should close this input stream as soon as possible, because the object contents aren't buffered in memory and stream directly from Qcloud COS. Further, failure to close this stream can cause the request pool to become blocked.

返回:

An input stream containing the contents of this object.

setObjectContent

public void setObjectContent(COSObjectInputStream objectContent)

Sets the input stream containing this object's contents.

参数:

objectContent - The input stream containing this object's contents.

getObjectContent()

setObjectContent

public void setObjectContent(InputStream objectContent)

getBucketName

public String getBucketName()

Gets the name of the bucket in which this object is contained.

返回:

The name of the bucket in which this object is contained.
