Method Detail

getRootNode

public Node getRootNode()

setSymbolTable

public void setSymbolTable(SymbolTable symbolTable)

getSymbolTable

public SymbolTable getSymbolTable()

getFieldsInExpr

public List getFieldsInExpr()

getMethodsInExpr

public List getMethodsInExpr()

isOnlyFieldInPath

public boolean isOnlyFieldInPath(String symbolName)

getAllPaths

public Set getAllPaths()

getSemanticRecordsInPath

public List getSemanticRecordsInPath(String path)

Get all the semantic records for this path. The semantic records contain parsed information about each element in the path. The returned is ordered based on the position of the element in the path. A path element can be a field or a method.

Parameters:

path -

Returns:

list of records

getAllSemanticRecordsInPath

public List getAllSemanticRecordsInPath(String path)

getFieldsInPath

public List getFieldsInPath(String path)

evaluate

public Object evaluate(Object object,
                       FieldValue fieldValueProtocol)
                throws ExpressionEvaluatorException

Description copied from class: Expression

Evaluates this against object using the supplied fieldValueProtocol to object field values from object during the evaluation. (Expressions may refer to fields of the objects against which they are evaluated.)

Specified by:

evaluate in class Expression

Parameters:

object - the object against which to evaluate this; may be null but in this case cannot have any fields dereferenced against it

fieldValueProtocol - the protocol to use to obtain field values from object during the evaulation; may be null in which case the default field value protocol for the class of object is used (see FieldValue.get(Object))

Throws:

ExpressionEvaluatorException

evaluate

public Object evaluate(Object object,
                       String expectedType,
                       FieldValue fieldValueProtocol)
                throws ExpressionEvaluatorException

Throws:

ExpressionEvaluatorException

evaluateSet

public void evaluateSet(Object object,
                        Object value,
                        FieldValue fieldValueProtocol)
                 throws ExpressionEvaluatorException

Throws:

ExpressionEvaluatorException

getFieldPaths

public Collection getFieldPaths()

Description copied from class: Expression

Returns the collection of fields paths referenced in this expression.

Specified by:

getFieldPaths in class Expression

toString

public String toString()

Description copied from class: Expression

Returns the String representation of this. The returned string should be the String that was used when this was ExpressionEvaluator.compile(java.lang.String) (ideally) or at least the string should be equivalent in the sense that it would result in the creation of an identically behaving expression.

Specified by:

toString in class Expression

printExprTree

public void printExprTree()
