OEParameter

class OEParameter

The OEParameter is an abstract base class. The parameters represent indivudual options in a OEOptions class, that can eventually translate to a parameter in a command-line interface application.

The OEParameter class defines the following public methods:
The following classes derive from this class:

AddAlias

bool AddAlias(std::string alias)

Adds an ‘alias’ name for this parameter. The alias must be a single word and begin with a '-'. This function returns true if the alias is valid and the add succeeds.

AddDetail

bool AddDetail(const std::string &detail)

Adds a line to the detailed description of the parameter. Return true if completed successfully.

AddIllegalRange

bool AddIllegalRange(std::string hi_val, std::string low_val)

Adds an illegal range for this parameter in string format. This function succeeds and returns true if the parameter can have illegal ranges.

AddIllegalValue

bool AddIllegalValue(std::string val)

Adds an illegal value in string format. This function succeeds and returns true if the parameter can have illegal values.

AddLegalRange

bool AddLegalRange(std::string hi_val, std::string low_val)

Adds a legal range for the parameter in string format. This function succeeds and returns true if the parameter can have legal ranges.

AddLegalValue

bool AddLegalValue(std::string val)

Adds a legal value in string format. This function succeeds and returns true if the parameter can have legal values.

AddStringDefault

bool AddStringDefault(std::string string_default)

Adds a default value in string format. This function succeeds and returns true if the default value can be set.

AddStringValue

bool AddStringValue(std::string string_value)

Adds a value for the parameter in string format. This function succeeds and returns true if the value can be set.

ClearDefaults

bool ClearDefaults()=0

Clear all currently set default values. Returns true if done successfully.

ClearValues

bool ClearValues()=0

Clear all currently set parameter values. Returns true if done successfully.

CreateCopy

OEParameter *CreateCopy() const

Creates a copy of this OEParameter instance.

GetAliases

OEIterBase<const std::string> *GetAliases() const

See AddAlias method.

GetBrief

std::string GetBrief() const

See SetBrief method.

GetDetail

OEIterBase<const std::string> *GetDetail() const

See AddDetail method.

GetHasDefault

bool GetHasDefault(unsigned int=0) const

Returns true if a default value for the parameter is set.

GetHasValue

bool GetHasValue(unsigned int=0) const

Returns true if the value of the OEParameter object is set.

GetIllegalRanges

OEIterBase<const std::pair<std::string, std::string> > * GetIllegalRanges() const

See AddIllegalRange method.

GetIllegalValues

OEIterBase<const std::string> *GetIllegalValues() const

See AddIllegalValue method.

GetIsList

bool GetIsList() const

See SetIsList method.

GetKeyless

unsigned int GetKeyless() const

See SetKeyless method.

GetLegalRanges

OEIterBase<const std::pair<std::string, std::string> > * GetLegalRanges() const

Returns the legal ranges in string format.

GetLegalValues

OEIterBase<const std::string> *GetLegalValues() const

Returns the legal values of the parameter in string format.

GetName

std::string GetName() const

See SetName method.

GetOrderPriority

int GetOrderPriority() const

See SetOrderPriority method.

GetRequired

bool GetRequired() const

See SetRequired method.

GetStringDefault

std::string GetStringDefault(unsigned int=0) const

Returns the string default of the parameter at the specified index. See AddStringDefault method.

GetStringDefaults

OEIterBase<const std::string> *GetStringDefaults() const

See AddStringDefault method.

GetStringValue

std::string GetStringValue(unsigned int=0) const

Returns the string value of the parameter at the specified index. See AddStringValue method.

GetStringValues

OEIterBase<const std::string> *GetStringValues() const

See AddStringValue method.

GetVisibility

unsigned int GetVisibility() const

See SetVisibility method.

IsLegalString

bool IsLegalString(std::string value) const

Returns if the specified value in the string format is a legal value. A setting is considered a legal value if it does not match and illegal value or fall within an illegal range (see OEParameter.AddIllegalValue and OEParameter.AddIllegalRange member functions of this class). Additionally if the parameter has at least one legal value or legal range the setting must match either a legal value or legal range.

IsSet

bool IsSet(unsigned int idx=0) const

Returns if the parameter current contains a setting, i.e., a default or an user-defined value.

IsSetToString

bool IsSetToString(std::string val) const

Returns if the parameters current setting (i.e., a default or an user-defined value) matches the specified string value.

Load

bool Load()

Converts the string defaults and values of this parameter into actual defaults and values. This function will return false if the string defaults or values cannot be converted to the actual defaults or values, as well as if the values do not satisfy the specified ranges.

LoadDefault

bool LoadDefault()

Converts the string defaults of this parameter into actual defaults. This function will return false if the string defaults cannot be converted to the actual defaults, as well as if the default values do not satisfy the specified ranges.

LoadValue

bool LoadValue()

Converts the user-defined string values of this parameter into actual values. This function will return false if the string values cannot be converted to the actual values, as well as if the values do not satisfy the specified ranges.

SetBrief

bool SetBrief(std::string brief)

Sets the brief description of the parameter.

SetIsList

bool SetIsList(bool is_list_parameter)

Set if the parameter is a list parameter, i.e., if the parameters can value of list of defaults or user-defined values. Default: False

SetKeyless

bool SetKeyless(unsigned int keyless)

Sets the keyless setting of the parameter. To enable a prrameter to be keyless the entry must be a non-zero value. A value of 0 (default) specifies the parameter to be not-keyless. Default: 0

SetName

bool SetName(std::string name)

Sets the name of the parameter, which must be a single word and begin with '-'.

SetOrderPriority

bool SetOrderPriority(int order)

Sets the order priority of the parameter, which is used to control the order parameters appear in help lists. Default: 0

SetRequired

bool SetRequired(bool required)

Sets the flag indicating if the parameter is required (i.e., must be guven a user-defined value). Default: False

SetStringDefault

bool SetStringDefault(std::string string_default)

Sets the default value of the parameter as a string. This string default is not converted into the read default until the OEParameter.LoadDefault member function is called. Default: None

SetStringValue

bool SetStringValue(std::string string_value)

Sets the value of the parameter as a string. This string value is not converted into the real value until the OEParameter.LoadValue member function is called. Default: None

SetVisibility

bool SetVisibility(unsigned int visibility)

Sets the visibility of the parameter. Valid settings are defined in the OEParamVisibility namespace. **Default: OEParamVisibility.Simple **
