public BatchStatement(BatchStatement.Type type,
                      VariableSpecifications bindVariables,
                      java.util.List<ModificationStatement> statements,
                      Attributes attrs)

Creates a new BatchStatement.

Parameters:

type - type of the batch

statements - the list of statements in the batch

attrs - additional attributes for statement (CL, timestamp, timeToLive)

Method Detail

getBindVariables

public java.util.List<ColumnSpecification> getBindVariables()

Description copied from interface: CQLStatement

Returns all bind variables for the statement

Specified by:

getBindVariables in interface CQLStatement

getPartitionKeyBindVariableIndexes

public short[] getPartitionKeyBindVariableIndexes()

Description copied from interface: CQLStatement

Returns an array with the same length as the number of partition key columns for the table corresponding to table. Each short in the array represents the bind index of the marker that holds the value for that partition key column. If there are no bind markers for any of the partition key columns, null is returned.

Specified by:

getPartitionKeyBindVariableIndexes in interface CQLStatement

getFunctions

public java.lang.Iterable<Function> getFunctions()

Description copied from interface: CQLStatement

Return an Iterable over all of the functions (both native and user-defined) used by any component of the statement

Specified by:

getFunctions in interface CQLStatement

Returns:

functions all functions found (may contain duplicates)

authorize

public void authorize(ClientState state)
               throws InvalidRequestException,
                      UnauthorizedException

Description copied from interface: CQLStatement

Perform any access verification necessary for the statement.

Specified by:

authorize in interface CQLStatement

Parameters:

state - the current client state

Throws:

InvalidRequestException

UnauthorizedException

validate

public void validate()
              throws InvalidRequestException

Throws:

InvalidRequestException

validate

public void validate(ClientState state)
              throws InvalidRequestException

Description copied from interface: CQLStatement

Perform additional validation required by the statment. To be overriden by subclasses if needed.

Specified by:

validate in interface CQLStatement

Parameters:

state - the current client state

Throws:

InvalidRequestException

getStatements

public java.util.List<ModificationStatement> getStatements()

execute

public ResultMessage execute(QueryState queryState,
                             QueryOptions options,
                             long queryStartNanoTime)

Description copied from interface: CQLStatement

Execute the statement and return the resulting result or null if there is no result.

Specified by:

execute in interface CQLStatement

Parameters:

queryState - the current query state

options - options for this query (consistency, variables, pageSize, ...)

queryStartNanoTime - the timestamp returned by System.nanoTime() when this statement was received

execute

public ResultMessage execute(QueryState queryState,
                             BatchQueryOptions options,
                             long queryStartNanoTime)

hasConditions

public boolean hasConditions()

Description copied from interface: CQLStatement

Whether or not this CQL Statement has LWT conditions

Specified by:

hasConditions in interface CQLStatement
