# IGESSolid_BooleanTree Class Reference

defines BooleanTree, Type <180> Form Number <0>
in package IGESSolid
The Boolean tree describes a binary tree structure
composed of regularized Boolean operations and operands,
in post-order notation.

## Public Member Functions
Standard_EXPORT | IGESSolid_BooleanTree ()
Standard_EXPORT void | Init (const Handle(IGESData_HArray1OfIGESEntity)&operands, const Handle(TColStd_HArray1OfInteger)&operations)
| This method is used to set the fields of the class BooleanTree - operands : Array containing pointer to DE of operands - operations : Array containing integer type for operations .
Standard_EXPORT Standard_Integer | Length () const
| returns the length of the post-order list
Standard_EXPORT Standard_Boolean | IsOperand (const Standard_Integer Index) const
| returns True if Index'th value in the post-order list is an Operand; else returns False if it is an Integer Operations raises exception if Index < 1 or Index > Length()
Standard_EXPORT Handle_IGESData_IGESEntity | Operand (const Standard_Integer Index) const
| returns the Index'th value in the post-order list only if it is an operand else returns NULL raises exception if Index < 1 or Index > Length()
Standard_EXPORT Standard_Integer | Operation (const Standard_Integer Index) const
| returns the Index'th value in the post-order list only if it is an operation else returns 0 raises exception if Index < 1 or Index > Length()
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
## Private Attributes
