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 class SimpleNode
Throws:
Exception

shallowCopy

public Expression shallowCopy()
Creates a copy of this expression node, without copying children.

Specified by:
shallowCopy in class Expression

appendAsEJBQL

public void appendAsEJBQL(Appendable out,
                          String rootId)
                   throws IOException
Description copied from class: Expression
Stores a String representation of Expression as EJBQL using a provided Appendable. DB path expressions produce non-standard EJBQL path expressions.

Overrides:
appendAsEJBQL in class SimpleNode
Throws:
IOException
Since:
3.2

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 class SimpleNode
Throws:
IOException
Since:
3.2

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 class Expression
