|---|
SimpleSelectStatementStateObject(StateObject parent)
Creates a new
SimpleSelectStatementStateObject. |
| Modifier and Type | Method and Description |
|---|---|
void |
accept(StateObjectVisitor visitor)
Visits this
StateObject by the given visitor. |
CollectionMemberDeclarationStateObject |
addDerivedCollectionDeclaration()
Adds a new derived collection declaration to the
FROM clause. |
CollectionMemberDeclarationStateObject |
addDerivedCollectionDeclaration(java.lang.String collectionValuedPath)
Adds a new derived collection declaration to the
FROM clause. |
DerivedPathIdentificationVariableDeclarationStateObject |
addDerivedPathDeclaration()
Adds a new derived identification variable declaration to the
FROM clause. |
DerivedPathIdentificationVariableDeclarationStateObject |
addDerivedPathDeclaration(java.lang.String path,
java.lang.String identificationVariable)
Adds a new derived identification variable declaration to the
FROM clause. |
protected AbstractFromClauseStateObject |
buildFromClause()
Creates the state object representing the
FROM clause. |
protected AbstractSelectClauseStateObject |
buildSelectClause()
Creates the state object representing the
SELECT clause. |
SimpleSelectStatement |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
SimpleFromClauseStateObject |
getFromClause()
Returns the state object representing the
FROM clause. |
ISimpleSelectExpressionStateObjectBuilder |
getSelectBuilder()
Creates and returns a new
ISimpleSelectExpressionStateObjectBuilder that can be used
to programmatically create a single select expression and once the expression is complete,
ISimpleSelectExpressionStateObjectBuilder.commit() will push the StateObject
representation of that expression as this clause's select expression. |
SimpleSelectClauseStateObject |
getSelectClause()
Returns the state object representing the
SELECT clause. |
void |
setExpression(SimpleSelectStatement expression)
Keeps a reference of the
parsed object object, which should only
be done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects. |
void |
setSelectItem(StateObject stateObject)
Sets the given
StateObject as the SELECT clause's select item. |
void |
setSelectItem(java.lang.String jpqlFragment)
Parses the given JPQL fragment and create the select item.
