close	back to summary
public void close() throws IOException Implements java.io.Closeable.close. Doc from java.io.Closeable.close. Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect. As noted in `AutoCloseable#close()`, cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the `Closeable` as closed, prior to throwing the `IOException`. Annotations @Override Exceptions IOException: if an I/O error occurs

public void close() throws IOException

Implements java.io.Closeable.close.

Doc from java.io.Closeable.close.

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable#close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.

getContent back to summary

getContent	back to summary
public InputStream getContent() throws IOException Implements org.apache.hc.core5.http.HttpEntity.getContent. Doc from org.apache.hc.core5.http.HttpEntity.getContent. Returns a content stream of the entity. `Repeatable` entities are expected to create a new instance of `InputStream` for each invocation of this method and therefore can be consumed multiple times. Entities that are not `repeatable` are expected to return the same `InputStream` instance and therefore may not be consumed more than once. If this entity belongs to an incoming HTTP message, calling `InputStream#close()` on the returned `InputStream` will try to consume the complete entity content to keep the connection alive. In cases where this is undesired, e.g. when only a small part of the content is relevant and consuming the complete entity content would be too inefficient, only the HTTP message from which this entity was obtained should be closed (if supported). Important Note Please note all entity implementations must ensure that all allocated resources are properly deallocated after the `InputStream#close()` method is invoked. Returns:InputStream content stream of the entity. Annotations @Override Exceptions IOException: if the stream could not be created

public InputStream getContent() throws IOException
