```
public abstract class CompositeResponseHandler
extends ReceivedDataHandler
```
This abstract class provides a mechanism to process each PDU of a composite response as it is received, such as for evaluating the status of the response for success.

Typically a private sub-class would be declared and instantiated with overriding methods to evaluate the success or failure of a storage or query or retrieve response.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`static java.lang.String`	`dumpAttributeListFromCommandOrData(byte[] bytes, java.lang.String transferSyntaxUID)`	Extract an `AttributeList` from the concatenated bytes that have been assembled from one or more PDUs and which make up an entire Command or Dataset.
`protected abstract void`	`evaluateStatusAndSetSuccess(AttributeList list)`	Extract the status information from a composite response and set the status flag accordingly.
`static AttributeList`	`getAttributeListFromCommandOrData(byte[] bytes, java.lang.String transferSyntaxUID)`	Extract an `AttributeList` from the concatenated bytes that have been assembled from one or more PDUs and which make up an entire Command or Dataset.
`static AttributeList`	`getAttributeListFromCommandOrData(byte[] bytes, java.lang.String transferSyntaxUID, int debugLevel)`	Extract an `AttributeList` from the concatenated bytes that have been assembled from one or more PDUs and which make up an entire Command or Dataset.
`int`	`getStatus()`	Get the response status Valid only after first calling `evaluateStatusAndSetSuccess()`
`protected void`	`makeUseOfDataSet(AttributeList list)`	Ignore any data set in the composite response (unless this method is overridden).
`void`	`sendPDataIndication(PDataPDU pdata, Association association)`	The code handling the reception of data on an `Association` calls this method to indicate that a PDU has been received (a P-DATA-INDICATION).
`boolean`	`wasSuccessful()`	Does the response include an indication of success ?
