SetSchemaNode
public class SetSchemaNode extends MiscellaneousStatementNode (Code)
A SetSchemaNode is the root of a QueryTree that represents a SET SCHEMA statement. It isn't replicated, but it generates a ConstantAction because it is basically easier than generating the code from scratch.

Method Summary
 intactivationKind()
     Returns the type of activation this class generates.
public  voidgenerate(ActivationClassBuilder acb, MethodBuilder mb)
    
 voidgenerateParameterValueSet(ActivationClassBuilder acb)
     Generate the code to create the ParameterValueSet, if necessary, when constructing the activation.
public  voidinit(Object schemaName, Object type)
    
public  ConstantActionmakeConstantAction()
     Create the Constant information that will drive the guts of Execution.
public  StringstatementToString()
    
public  StringtoString()
     Convert this object to a String.



Method Detail
activationKind
int activationKind()(Code)
Returns the type of activation this class generates. NEED_PARAM_ACTIVATION orNEED_NOTHING_ACTIVATION depending on params



generate
public void generate(ActivationClassBuilder acb, MethodBuilder mb) throws StandardException(Code)
Generate code, need to push parameters
Parameters:
  acb - The ActivationClassBuilder for the class being built
Parameters:
  mb - the method for the execute() method to be built
exception:
  StandardException - Thrown on error



generateParameterValueSet
void generateParameterValueSet(ActivationClassBuilder acb) throws StandardException(Code)
Generate the code to create the ParameterValueSet, if necessary, when constructing the activation. Also generate the code to call a method that will throw an exception if we try to execute without all the parameters being set.
Parameters:
  acb - The ActivationClassBuilder for the class we're building



init
public void init(Object schemaName, Object type)(Code)
Initializer for a SetSchemaNode
Parameters:
  schemaName - The name of the new schema
Parameters:
  type - Type of schema name could be USER or dynamic parameter



makeConstantAction
public ConstantAction makeConstantAction() throws StandardException(Code)
Create the Constant information that will drive the guts of Execution.
exception:
  StandardException - Thrown on failure



statementToString
public String statementToString()(Code)



toString
public String toString()(Code)
Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing. This object as a String
