Method Detail

evaluateNode
protected Object evaluateNode(Object o) throws Exception
Description copied from class:SimpleNode
Evaluates itself with object, pushing result on the stack.- Specified by:
evaluateNode
in classSimpleNode
- Throws:
Exception
-
shallowCopy
public Expression shallowCopy()
Creates a copy of this expression node, without copying children.- Specified by:
shallowCopy
in classExpression
-
getType
public int getType()
Description copied from class:Expression
Returns a type of expression. Most common types are defined as public static fields of this interface.- Overrides:
getType
in classExpression
-
appendAsString
public void appendAsString(Appendable out) throws IOException
Description copied from class:Expression
Appends own content as a String to the provided Appendable.- Overrides:
appendAsString
in classSimpleNode
- Throws:
IOException
- Since:
- 4.0
-
appendAsEJBQL
public void appendAsEJBQL(List<Object> parameterAccumulator, Appendable out, String rootId) throws IOException
Description copied from class:Expression
Stores a String representation of Expression as EJBQL using a provided PrintWriter. DB path expressions produce non-standard EJBQL path expressions. If the parameterAccumulator is supplied then as the EJBQL is output, it may load parameters into this list. In this case, the EJBQL output will contain reference to positional parameters. If no parameterAccumulator is supplied and a scalar type is encountered for which there is no EJBQL literal representation (such as dates) then this method will throw a runtime exception to indicate that it was not possible to generate a string-only representation of the Expression in EJBQL.- Overrides:
appendAsEJBQL
in classSimpleNode
- Throws:
IOException
- Since:
- 4.0
-
getExpressionOperator
protected String getExpressionOperator(int index)
- Specified by:
getExpressionOperator
