public String getQueryString()

Description copied from class: Statement

Returns the query string for this statement.

buildQueryString

protected String buildQueryString()

getRoutingKey

public ByteBuffer getRoutingKey()

Description copied from class: Query

Returns the routing key (in binary raw form) to use for token aware routing of this query.

The routing key is optional in that implementers are free to return null. The routing key is an hint used for token-aware routing (see TokenAwarePolicy), and if provided should correspond to the binary value for the query partition key. However, not providing a routing key never causes a query to fail and if the load balancing policy used is not token aware, then the routing key can be safely ignored.

Returns:

the routing key for this query or null.

setDirty

protected void setDirty()

isCounterOp

protected boolean isCounterOp()

setCounterOp

protected void setCounterOp(boolean isCounterOp)
