ctx - the ExecutionContext to use to create commands

term - the parsed NodeTerm used to create the relevant Statement

listBindVars - the indexed bind variables

namedBindVars - the named bind variables

Returns:

an executable instance of a Statement

createInsertKey

protected Object createInsertKey(Term termKey,
 com.tangosol.coherence.dslquery.internal.UpdateSetListMaker transformer,
 Object oValue)

Create the key to use in the insert statement.

Parameters:

termKey - the AST representing the Key term

transformer - the UpdateSetListMaker that will create the key instance

oValue - the value being inserted that will be used to call its getKey method if no key term is present

Returns:

the value to use as the key for the insert

Throws:

CohQLException - if there are any errors creating the key instance

createInsertValue

protected Object createInsertValue(Term termValue,
 com.tangosol.coherence.dslquery.internal.UpdateSetListMaker transformer)

Create the instance of the value that will be inserted into the cache.

Parameters:

termValue - the AST term to use to create the value

transformer - the UpdateSetListMaker that can create values from AST terms

Returns:

an instance of a value to insert into the cache

Throws:

CohQLException - if any errors occur creating the value

protected com.tangosol.coherence.dslquery.internal.UpdateSetListMaker createUpdateSetListMaker(ExecutionContext ctx,
 List listBindVars,
 ParameterResolver namedBindVars)

Create an UpdateSetListMaker.

Parameters:

ctx - the ExecutionContext to use

listBindVars - the indexed bind variables to pass to the UpdateSetListMaker

namedBindVars - the named bind variables to pass to the UpdateSetListMaker

Returns:

an UpdateSetListMaker
