Field Detail

constraints

private final java.util.List<TableName> constraints

List of strings representing the constraints we want to set. If empty, this means ALL.

deferred

private final boolean deferred

Encodes IMMEDIATE (false), DEFERRED (true)

Constructor Detail

SetConstraintsNode

SetConstraintsNode(java.util.List<TableName> constraints,
                   boolean deferred,
                   ContextManager cm)

Parameters:

constraints - List of strings representing the constraints we want to set (empty means ALL).

deferred - Encodes IMMEDIATE (false) or DEFERRED (true)

cm - The context manager

Method Detail

toString

public java.lang.String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class StatementNode

Returns:

This object as a String

formatList

java.lang.String formatList(java.util.List<TableName> constraints)

statementToString

public java.lang.String statementToString()

Specified by:

statementToString in class StatementNode

makeConstantAction

public ConstantAction makeConstantAction()
                                  throws StandardException

Create the Constant information that will drive the guts of Execution.

Overrides:

makeConstantAction in class QueryTreeNode

Throws:

StandardException - Thrown on failure

bindStatement

public void bindStatement()
                   throws StandardException

Description copied from class: StatementNode

Perform the binding operation statement. Binding consists of permissions checking, view resolution, datatype resolution, and creation of a dependency list (for determining whether a tree or plan is still up to date). This bindStatement() method does nothing. Each StatementNode type that can appear at the top of a tree can override this method with its own bindStatement() method that does "something".

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

acceptChildren

void acceptChildren(Visitor v)
             throws StandardException

Description copied from class: QueryTreeNode

Accept a visitor on all child nodes. All sub-classes that add fields that should be visited, should override this method and call accept(v) on all visitable fields, as well as super.acceptChildren(v) to make sure all visitable fields defined by the super-class are accepted too.

Overrides:

acceptChildren in class QueryTreeNode

Parameters:

v - the visitor

Throws:

StandardException - on errors raised by the visitor
