FieldAccessExp

public FieldAccessExp(Exp exp,
                      String id)

Default constructor. Sets this object as the exp's parent.

Parameters:

exp - The exp. Must be non-null.

id - The id. Must be non-null.

Method Detail

setConstant

public void setConstant()

Sets to indicate a constant/enum access.

isConstant

public boolean isConstant()

Determines a constant/enum access.

Returns:

True, if a constant/enum access. False, otherwise.

setExp

public void setExp(Exp newExp)

Sets the exp. Sets this object as the exp's parent.

Parameters:

newExp - The new exp. Must be non-null.

getExp

public Exp getExp()

Gets the exp.

Returns:

The exp. Non-null.

setFieldIndex

public void setFieldIndex(int newFieldIndex)

Sets the field index if a record/array field access.

Parameters:

newFieldIndex - The new field index. Must be greater than or equal to zero.

getFieldIndex

public int getFieldIndex()

Gets the field index if a record/array field access.

Returns:

The field index. Greater than or equal than zero.

setId
