Constructor Detail

ExecutionDataReader

public ExecutionDataReader(InputStream input)
Creates a new reader based on the given input stream input. Depending on the nature of the underlying stream input should be buffered as most data is read in single bytes.

Parameters:
input - input stream to read execution data from
Method Detail

setSessionInfoVisitor

public void setSessionInfoVisitor(ISessionInfoVisitor visitor)
Sets an listener for session information.

Parameters:
visitor - visitor to retrieve session info events

setExecutionDataVisitor

public void setExecutionDataVisitor(IExecutionDataVisitor visitor)
Sets an listener for execution data.

Parameters:
visitor - visitor to retrieve execution data events

read

public boolean read()
             throws IOException,
                    IncompatibleExecDataVersionException
Reads all data and reports it to the corresponding visitors. The stream is read until its end or a command confirmation has been sent.

Returns:
true if additional data can be expected after a command has been executed. false if the end of the stream has been reached.
Throws:
IOException - might be thrown by the underlying input stream
IncompatibleExecDataVersionException - incompatible data version from different JaCoCo release

readBlock

protected boolean readBlock(byte blocktype)
                     throws IOException
Reads a block of data identified by the given id. Subclasses may overwrite this method to support additional block types.

Parameters:
blocktype - block type
Returns:
true if there are more blocks to read
Throws:
IOException - might be thrown by the underlying input stream
