Constructor Detail

NewAST

public NewAST(antlr.Token token)
Create a new "new" expression AST

Parameters:
token - the token represented by this AST node
Method Detail

parseComplete

public void parseComplete()
Description copied from class: JavaAST
Compute any derived attributes that must be evaluated after the initial parse. The default action is to just tell your children that the parse is complete.

Overrides:
parseComplete in class JavaAST

computeType

protected Type computeType()
Description copied from class: ExpressionAST
Compute the type of this expression

Specified by:
computeType in class ExpressionAST
Returns:
the type of this expression

computeValue

protected Object computeValue()
Description copied from class: ExpressionAST
Compute the constant value of this expression, if any

Specified by:
computeValue in class ExpressionAST
Returns:
the constant value (if any) of this expression, as a wrapped primitive type or an object type

computeExceptions

protected Type[] computeExceptions()
Description copied from class: ExpressionAST
Compute the checked exception types that might be thrown by this expression

Specified by:
computeExceptions in class ExpressionAST
Returns:
an array of types representing the exceptions that this expression might throw

getVarList

public VarList getVarList()
Description copied from class: ExpressionAST
Get the list of variables read and written by this expression

Specified by:
getVarList in class ExpressionAST
Returns:
the list of variables read and written by this expression

getTypeName

public IdentifierAST getTypeName()
Get the name of the type to instantiate

Returns:
the name of the type

getDimensions

public int getDimensions()
Get the number of dimensions in the array to create

Returns:
the number of dimensions, or zero if this use of new is creating an object

getParameters

public ListAST getParameters()
Get the parameters to the object constructor

Returns:
a list containing the parameters to the constructor, or null if this use of new is creating an array
