| forCallStatement | | protected boolean forCallStatement(Code) | | |
| castToPrimitive | | public void castToPrimitive(boolean booleanValue)(Code) | | Toggles whether the code generator should add a cast to extract a primitive
value from an object.
Parameters:
booleanValue - true if we want the code generator to add a castfalse otherwise |
| generate | | final protected void generate(ActivationClassBuilder acb, MethodBuilder mb) throws StandardException(Code) | | Do the code generation for this node. Call the more general
routine that generates expressions.
Parameters:
acb - The ActivationClassBuilder for the class being built
Parameters:
mb - the method the expression will go into
exception:
StandardException - Thrown on error |
| generateExpression | | abstract protected void generateExpression(ExpressionClassBuilder acb, MethodBuilder mb) throws StandardException(Code) | | General logic shared by Core compilation and by the Replication Filter
compiler. Every child of ValueNode must implement one of these methods.
Parameters:
acb - The ExpressionClassBuilder for the class being built
Parameters:
mb - the method the expression will go into
exception:
StandardException - Thrown on error |
| generateReceiver | | protected boolean generateReceiver(ExpressionClassBuilder acb, MethodBuilder mb) throws StandardException(Code) | | Generate the expression that evaluates to the receiver. This is
for the case where a java expression is being returned to the SQL
domain, and we need to check whether the receiver is null (if so,
the SQL value should be set to null, and this Java expression
not evaluated). Instance method calls and field references have
receivers, while class method calls and calls to constructors do
not. If this Java expression does not have a receiver, this method
returns null.
The implementation of this method should only generate the receiver
once and cache it in a field. This is because there will be two
references to the receiver, and we want to evaluate it only once.
Parameters:
acb - The ExpressionClassBuilder for the class being built
Parameters:
mb - the method the expression will go into True if has compiled receiver.
exception:
StandardException - Thrown on error |
| generateReceiver | | final protected boolean generateReceiver(ExpressionClassBuilder acb, MethodBuilder mb, JavaValueNode receiver) throws StandardException(Code) | | Generate the expression that evaluates to the receiver. This is
for the case where a java expression is being returned to the SQL
domain, and we need to check whether the receiver is null (if so,
the SQL value should be set to null, and this Java expression
not evaluated). Instance method calls and field references have
receivers, while class method calls and calls to constructors do
not. If this Java expression does not have a receiver, this method
returns null.
This also covers the case where a java expression is being returned
to the Java domain. In this case, we need to check whether the
receiver is null only if the value returned by the Java expression
is an object (not a primitive type). We don't want to generate the
expression here if we are returning a primitive type to the Java
domain, because there's no point in checking whether the receiver
is null in this case (we can't make the expression return a null
value).
Only generate the receiver once and cache it in a field. This is
because there will be two references to the receiver, and we want
to evaluate it only once.
Parameters:
acb - The ActivationClassBuilder for the class being built
Parameters:
mb - the method the expression will go into
Parameters:
receiver - The query tree form of the receiver expression The compiled receiver, if any.
exception:
StandardException - Thrown on error |
| getJSQLType | | public JSQLType getJSQLType() throws StandardException(Code) | | Get the JSQLType that corresponds to this node. Could be a SQLTYPE,
a Java primitive, or a Java class.
the corresponding JSQLType |
| getOrderableVariantType | | protected int getOrderableVariantType() throws StandardException(Code) | | Return the variant type for the underlying expression.
The variant type can be:
VARIANT - variant within a scan
(method calls and non-static field access)
SCAN_INVARIANT - invariant within a scan
(column references from outer tables)
QUERY_INVARIANT - invariant within the life of a query
(constant expressions)
The variant type for the underlying expression. |
| getReceiverExpression | | final protected void getReceiverExpression(ExpressionClassBuilder acb, MethodBuilder mb, JavaValueNode receiver) throws StandardException(Code) | | Get an expression that has the value of the receiver. If a field
holding the receiver value was already generated, use that. If not,
generate the receiver value.
Parameters:
acb - The ExpressionClassBuilder for the class we're generating
Parameters:
mb - the method the expression will go into
Parameters:
receiver - The query tree form of the receiver expression
exception:
StandardException - Thrown on error |
