Method Summary

Modifier and TypeMethod and Description
public void
addUpdatesToQuery(UpdateAllQuery theQuery, GenerationContext context)

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

protected Expression
getExpressionForNode(Node node, Class<?> referenceClass, GenerationContext context)

Create an expression to represent one of the nodes on a SetToNode.

qualifyAttributeAccess(ParseTreeContext context)

Overrides org.eclipse.persistence.internal.jpa.parsing.Node.qualifyAttributeAccess.

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.

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.

getExpressionForNodeback to summary
protected Expression getExpressionForNode(Node node, 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.

public Node qualifyAttributeAccess(ParseTreeContext context)

Overrides org.eclipse.persistence.internal.jpa.parsing.Node.qualifyAttributeAccess.

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.
