Member Function Documentation

ExprTree * AttributeReference::Copy (  )  const [virtual]

Return a copy of this attribute reference.

Implements ExprTree.

virtual ExprTree* AttributeReference::Copy (  )  const [virtual]

Return a copy of this attribute reference.

Implements ExprTree.

bool AttributeReference::CopyFrom ( const AttributeReference &  ref  ) 

Copy from the given reference into this reference.

Parameters:
ref The reference to copy from.
Returns:
true if the copy succeeded, false otherwise.
bool AttributeReference::CopyFrom ( const AttributeReference &  ref  ) 

Copy from the given reference into this reference.

Parameters:
ref The reference to copy from.
Returns:
true if the copy succeeded, false otherwise.
void AttributeReference::GetComponents ( ExprTree *&  expr,
std::string &  attr,
bool &  abs 
) const

Deconstructor to get the components of an attribute reference

Parameters:
expr The expression part of the reference (NULL for absolute or simple references)
attr The name of the attribute being referred to
abs true iff the reference is absolute (i.e., .attr)
void AttributeReference::GetComponents ( ExprTree *&  expr,
std::string &  attr,
bool &  abs 
) const

Deconstructor to get the components of an attribute reference

Parameters:
expr The expression part of the reference (NULL for absolute or simple references)
attr The name of the attribute being referred to
abs true iff the reference is absolute (i.e., .attr)
static AttributeReference* AttributeReference::MakeAttributeReference ( ExprTree *  expr,
const std::string &  attrName,
bool  absolute = false 
) [static]

Factory method to create attribute reference nodes.

Parameters:
expr The expression part of the reference (i.e., in case of expr.attr). This parameter is NULL if the reference is absolute (i.e., .attr) or simple (i.e., attr).
attrName The name of the reference. This string is duplicated internally.
absolute True if the reference is an absolute reference (i.e., in case of .attr). This parameter cannot be true if expr is not NULL
static AttributeReference* AttributeReference::MakeAttributeReference ( ExprTree *  expr,
const std::string &  attrName,
bool  absolute = false 
) [static]

Factory method to create attribute reference nodes.

Parameters:
expr The expression part of the reference (i.e., in case of expr.attr). This parameter is NULL if the reference is absolute (i.e., .attr) or simple (i.e., attr).
attrName The name of the reference. This string is duplicated internally.
absolute True if the reference is an absolute reference (i.e., in case of .attr). This parameter cannot be true if expr is not NULL
bool AttributeReference::SameAs ( const ExprTree *  tree  )  const [virtual]

Is this attribute reference the same as another?

Parameters:
tree The reference to compare with
Returns:
true if they are the same, false otherwise.

Implements ExprTree.

virtual bool AttributeReference::SameAs ( const ExprTree *  tree  )  const [virtual]

Is this attribute reference the same as another?

Parameters:
tree The reference to compare with
Returns:
true if they are the same, false otherwise.

Implements ExprTree.
