Method Detail

writeRequest

public void writeRequest(java.nio.ByteBuffer out)

Description copied from class: AbstractSessionRequest

Writes out the request header and session string. Subclasses must override this if needed, and their implementation must call this method as the first operation.

Parameters:

out - output buffer.

handleMessage

public AbstractRequest.JobStatus handleMessage(Header header,
                                               java.nio.ByteBuffer in)

Description copied from class: AbstractRequest

Abstract method to handle response message. This implementation only validates request and command. Must be overwritten by concrete implementation. Some concrete implementations may call this one at the beginning to check the sanity of the response.

Parameters:

header - parsed response header.

in - input buffer with the rest of the data (after header has been parsed).

getExchangeCode

public java.lang.String getExchangeCode()

getSymbolCode

public java.lang.String getSymbolCode()

getVolumeStyle

public VolumeStyleEnum getVolumeStyle()

getError

public final OTError getError()

fireCompleted

public final void fireCompleted(OTError error)

Internal method: used to wake up threads sleeping in waitForCompletion().

isCompleted

public final boolean isCompleted()

waitForCompletion

public final boolean waitForCompletion(long millis)

Convenience method: blocks calling thread until request finishes, or the specified number of milliseconds elapses. Note that if request was not submitted, this method returns immediately with no error.

Parameters:

millis - how long to wait for completion.

waitForCompletion

public final void waitForCompletion()

Convenience method: blocks calling thread until request finishes. Note that if request was not submitted, this method returns immediately with no error.
