Constructor Detail

InitialValue

public InitialValue(Exp value)

Node for initial value of a variable, left as its natural type.

Parameters:

value - The value initially assigned to the global or local which owns this node. Must be non-null.

InitialValue

public InitialValue(Exp value,
                    ASTType coercedType)

Node for initial value of a variable, casted to a particular type.

Parameters:

value - The value initially assigned to the global or local which owns this node. Must be non-null.

coercedType - The type to which this initial value is casted. Must be non-null.

Method Detail

setValue

public void setValue(Exp newValue)

Sets the initial value. This InitialValue is made the parent of newValue.

Parameters:

newValue - The new value. Must be non-null.

getValue

public Exp getValue()

Gets the initial value.

setCoercedType

public void setCoercedType(ASTType newType)

Sets the type to which the initial value is cast. This InitialValue is made the parent of newType.

Parameters:

newType - The new casted type. Must be non-null.

getOptionalCoercedType

public ASTType getOptionalCoercedType()

Gets the type to which this value is cast.

Returns:

The coerced type, or null if none is specified.

setParent

public void setParent(IInitialValueParent newParent)

Make newParent the parent of this node.

Parameters:

newParent - The new syntax tree node which owns this InitialValue. Must be non-null.

getParent

public IInitialValueParent getParent()

Gets the parent of this node.

clone

Clones this object (deep clone); including location info.

Specified by:

clone in class Node

Returns:

The clone of this object. Non-null.

visit
