Member Function Documentation

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)

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

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.

bool operator== (  const AttributeReference &  ref1, const AttributeReference &  ref2 )  [friend]

Are the two attribute references the same? Parameters: ref1  An attribute reference ref2  Another attribute reference Returns: true if they are the same, false otherwise.
