Method Detail

and

public Delete.Options and(Using using)

Adds the provided option.

Parameters:

using - a DELETE option.

Returns:

this Options object.

where

public Delete.Where where(Clause clause)

Adds a where clause to the DELETE statement these options are part of.

Parameters:

clause - clause to add.

Returns:

the WHERE clause of the DELETE statement these options are part of.

getQueryString

public String getQueryString()

Description copied from class: Statement

Returns the query string for this statement.

Returns:

a valid CQL query string.

buildQueryString

protected StringBuilder 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()

setConsistencyLevel

public Query setConsistencyLevel(ConsistencyLevel consistency)

Description copied from class: Query

Sets the consistency level for the query.

The default consistency level, if this method is not called, is ConsistencyLevel.ONE.

Overrides:

setConsistencyLevel in class Query

Parameters:

consistency - the consistency level to set.

Returns:

this Query object.

getConsistencyLevel

public ConsistencyLevel getConsistencyLevel()

Description copied from class: Query

Returns the consistency level.

Overrides:

getConsistencyLevel in class Query

Returns:

the consistency level, which is ConsistencyLevel.ONE if no consistency level has been specified.

enableTracing

public Query enableTracing()

Description copied from class: Query

Enables tracing for this query. By default (that is unless you call this method), tracing is not enabled.

Overrides:

enableTracing in class Query

Returns:

this Query object.

disableTracing

public Query disableTracing()

Description copied from class: Query

Disables tracing for this query.

Overrides:

disableTracing in class Query

Returns:

this Query object.

isTracing

public boolean isTracing()

Description copied from class: Query

Returns whether tracing is enabled for this query or not.

Overrides:

isTracing in class Query

Returns:

true if this query has tracing enabled, false otherwise.

setRetryPolicy

public Query setRetryPolicy(RetryPolicy policy)

Description copied from class: Query

Sets the retry policy to use for this query.

The default retry policy, if this method is not called, is the one returned by Policies.getRetryPolicy() in the cluster configuration. This method is thus only useful in case you want to punctually override the default policy for this request.

Overrides:

setRetryPolicy in class Query

Parameters:

policy - the retry policy to use for this query.

Returns:

this Query object.

getRetryPolicy

public RetryPolicy getRetryPolicy()

Description copied from class: Query

Returns the retry policy sets for this query, if any.

Overrides:

getRetryPolicy in class Query

Returns:

the retry policy sets specifically for this query or null if no query specific retry policy has been set through Query.setRetryPolicy(com.datastax.driver.core.policies.RetryPolicy) (in which case the Cluster retry policy will apply if necessary).

setCounterOp

protected void setCounterOp(boolean isCounterOp)
