Method Detail

addUpdatesToQuery

public void addUpdatesToQuery(UpdateAllQuery theQuery,
                              GenerationContext context)

Iterate through the updates in this query and build expressions for them. Set the built expressions on the query.

qualifyAttributeAccess

public Node qualifyAttributeAccess(ParseTreeContext context)

INTERNAL Check the update item node for a path expression starting with a unqualified field access and if so, replace it by a qualified field access.

Overrides:

qualifyAttributeAccess in class Node

validate

public void validate(ParseTreeContext context)

INTERNAL Validate node.

Overrides:

validate in class Node

getExpressionForNode

protected Expression getExpressionForNode(Node node,
                                          java.lang.Class referenceClass,
                                          GenerationContext context)

Create an expression to represent one of the nodes on a SetToNode. We will assume that set_to nodes change elements that are direct mappings on the reference class of the query.

setAssignmentNodes

public void setAssignmentNodes(java.util.List nodes)

INTERNAL
