This class gives a way of conversion between the value of an enumeration and its representation in STEP An enumeration corresponds to an integer with reserved values, which begin to 0 In STEP, it is represented by a name in capital letter and limited by two dots, e.g. .UNKNOWN. More...

| Creates an EnumTool with definitions given by e0 .. e<max> Each definition string can bring one term, or several separated by blanks. Each term corresponds to one value of the enumeration, if dots are not presents they are added. | |
| void | AddDefinition (const Standard_CString term) |
| Processes a definition, splits it according blanks if any empty definitions are ignored A null definition can be input by given "$" :the corresponding position is attached to "null/undefined" value (as one particular item of the enumeration list) See also IsSet. | |
| Standard_Boolean | IsSet () const |
| Returns True if at least one definition has been entered after creation time (i.e. by AddDefinition only) | |
| Standard_Integer | MaxValue () const |
| Returns the maximum integer for a suitable value Remark : while values begin at zero, MaxValue is the count of recorded values minus one. | |
| void | Optional (const Standard_Boolean mode) |
| Sets or Unsets the EnumTool to accept undefined value (for optional field). Ignored if no null value is defined (by "$") Can be changed during execution (to read each field), Default is True (if a null value is defined) | |
| Standard_Integer | NullValue () const |
| Returns the value attached to "null/undefined value" If none is specified or if Optional has been set to False, returns -1 Null Value has been specified by definition "$". | |
| const TCollection_AsciiString & | Text (const Standard_Integer num) const |
| Returns the text which corresponds to a given numeric value It is limited by dots If num is out of range, returns an empty string. | |
| Standard_Integer | Value (const Standard_CString txt) const |
| Returns the numeric value found for a text The text must be in capitals and limited by dots A non-suitable text gives a negative value to be returned. | |

This class gives a way of conversion between the value of an enumeration and its representation in STEP An enumeration corresponds to an integer with reserved values, which begin to 0 In STEP, it is represented by a name in capital letter and limited by two dots, e.g. .UNKNOWN.
EnumTool works with integers, it is just required to cast between an integer and an enumeration of required type.
Its definition is intended to allow static creation in once, without having to recreate once for each use.
It is possible to define subclasses on it, which directly give the good list of definition texts, and accepts a enumeration of the good type instead of an integer
Creates an EnumTool with definitions given by e0 .. e<max> Each definition string can bring one term, or several separated by blanks. Each term corresponds to one value of the enumeration, if dots are not presents they are added.
Such a static constructor allows to build a static description as : static StepData_EnumTool myenumtool("e0","e1"...); then use it without having to initialise it
A null definition can be input by given "$" :the corresponding position is attached to "null/undefined" value (as one particular item of the enumeration list)
| void StepData_EnumTool::AddDefinition | ( | const Standard_CString | term | ) |
Processes a definition, splits it according blanks if any empty definitions are ignored A null definition can be input by given "$" :the corresponding position is attached to "null/undefined" value (as one particular item of the enumeration list) See also IsSet.
| Standard_Boolean StepData_EnumTool::IsSet | ( | ) | const |
Returns True if at least one definition has been entered after creation time (i.e. by AddDefinition only)
This allows to build a static description by a first pass : static StepData_EnumTool myenumtool("e0" ...); ... if (!myenumtool.IsSet()) { for further inits myenumtool.AddDefinition("e21"); ... }
| Standard_Integer StepData_EnumTool::MaxValue | ( | ) | const |
Returns the maximum integer for a suitable value Remark : while values begin at zero, MaxValue is the count of recorded values minus one.
| Standard_Integer StepData_EnumTool::NullValue | ( | ) | const |
Returns the value attached to "null/undefined value" If none is specified or if Optional has been set to False, returns -1 Null Value has been specified by definition "$".
| void StepData_EnumTool::Optional | ( | const Standard_Boolean | mode | ) |
Sets or Unsets the EnumTool to accept undefined value (for optional field). Ignored if no null value is defined (by "$") Can be changed during execution (to read each field), Default is True (if a null value is defined)
| const TCollection_AsciiString & StepData_EnumTool::Text | ( | const Standard_Integer | num | ) | const |
Returns the text which corresponds to a given numeric value It is limited by dots If num is out of range, returns an empty string.
| Standard_Integer StepData_EnumTool::Value | ( | const Standard_CString | txt | ) | const |
Returns the numeric value found for a text The text must be in capitals and limited by dots A non-suitable text gives a negative value to be returned.
| Standard_Integer StepData_EnumTool::Value | ( | const TCollection_AsciiString & | txt | ) | const |
Same as above but works on an AsciiString.
