Detailed Description

Non-templated base class for generic parameter access and iteration.

Note: This is a pure-virtual non-constructable class; Parameter type (getTypeName) is invariant for a given Parameter. It is the responsibility of the subclass to enforce this

See also: sparta::ParameterSet; sparta::Parameter

Allows values to be set and read as strings. Default value and description can also be read as a string. To access value by its internal type, a subclass must be used. For a model to consume parameters, the use of a sparta::ParameterSet subclass is expected. Such as class would allow direct access to parameters in their native types instead of through the generic string-based API provided by ParameterBase.

Subclasses are responsible for incremeneting read and write counts when setting or reading the value as its actual type or as a string. Serializing the Parameter does not count as a read. Refer to incrementReadCount_ and incrementWriteCount_. Read count must always be reset to 0 when the parameter is set (whether changed or not) and when initialized.

Member Typedef Documentation

◆ const_iterator

typedef class sparta::ParameterBase::ParameterValueIterator sparta::ParameterBase::const_iterator

Generic value iterator for a SINGLE parameter which represents values ONLY as std::string.

Note: Can be used on any parameter.; Useful for displaying parameter contents without knowing parameter type.

See also: sparta::ParameterBase::isVector; sparta::ParameterBase::begin()

For Scalar parameters (including std::string), this itererator will cover exactly 1 element. For vector parameters, this iterator will cover any number of elements.

Iterates values in a ParameterBase by index.

Warning: Uses a dynamic cast. Do not use in performance critical code

See also: getValueAsString; getTypeName

Definition at line 2539 of file Parameter.hpp.

Parameters

indices Indices into this parameter. The size of indices must be less than the dimensionality of this parameter in order to refer to a vector with a size. If the internal parameter value 'v' is of type vector<vector<vector<int>>>, then indices = {0,1} effectively refers to v[0][1].size(). indices = {0,1,1} would be illegal because v[0][1][1] would refer to an integer, which is not a vector and thus has no vector size. If any index in indices

peek If true, do not increment the read count

Implemented in sparta::Parameter< ValueType >.

◆ getWriteCount()

uint32_t sparta::ParameterBase::getWriteCount ( ) const

Precondition: Must not have completed the sparta::TreeNode::TREE_CONFIGURING phase.

Exceptions

SpartaException if TreeNode base has already passed the TREE_CONFIGURING phase (sparta::TreeNode::isConfigured).

◆ isDefaultOverridden()

virtual bool sparta::ParameterBase::isDefaultOverridden ( ) const

pure virtual

Has the default value (NOT the current value) for parameter been overridden in any way (including partially changed).

Warning: This does not provide information about the current value held by the parameter, only the default value.

In SPARTA, parameter defaults are supplied at construction-time through constants or constructors, but these defaults can also be changed during initialization in order to support custom architectural configuration baselines. An overridden default value does not necessarily imply a change in the current value held by this parameter. To see if the current value (getValueAsString or Parameter<t>::getValue) has changed, use isDefault (i.e. is this parameter's value equal to the default?)

Implemented in sparta::Parameter< ValueType >.

◆ resizeVectorsFromString()

virtual void sparta::ParameterBase::resizeVectorsFromString ( const std::vector< uint32_t > & indices )

pure virtual

Attempt to resize a vector nested within this parameter to contain the vector indicated by indices.

Parameters

indices Set of indices referring to nested vectors that must be accessible (at a minimum) by future reads. Nested vetors containing non-vector types will not be resized by this method. See resizeVectorsFromString_ for implementation details

Implemented in sparta::Parameter< ValueType >.

◆ restoreValueFromDefault()

void sparta::ParameterBase::restoreValueFromDefault ( )

Attempts to restore the devalue value of this parameter.

Precondition: This parameter must not have been read yet.

Precondition: Must not be finalized and must not have been read yet

Definition at line 271 of file Parameter.hpp.

Here is the call graph for this function:

◆ setItemValueFromString()

void sparta::ParameterBase::setItemValueFromString	(	const std::vector< uint32_t > &	indices,
		const std::string &	str
	)

Attempts to assign a value to this nested vector Parameter from a string at a position within the vector indicated by indices.

Parameters

indices Set of indices indicating positions in a nested vector parameter type. For example, a parameter of type vector<vector<vector<string>>> with an internal representation referred to as 'p' may have indices [1,2,3] to effectively set str at p[1][2][3]. Internal vector will be resized to contain a location as described by indices if needed. Values in items created by a resize are undefined. If indices.size() is 0, treats this type as if it is a non-stl::vector parameter and directly assigns the lexically cast value of str string to the parameter's internal value

str String value to assign to the element identified by indices. This string will be lexically cast to the approprate internal type as in setValueFromString

◆ setItemValueFromStringImpl_()

virtual void sparta::ParameterBase::setItemValueFromStringImpl_	(	const std::vector< uint32_t > &	indices,
		const std::string &	str
	)

◆ setStringQuote()

std::string sparta::ParameterBase::setStringQuote ( const std::string & s )

Parameters

s	String quote sequence (defaults to empty string)

Returns: The previous string quote sequence

Definition at line 755 of file Parameter.hpp.

◆ setValueFromString()

void sparta::ParameterBase::setValueFromString	(	const std::string &	str,
		bool	poke = `false`
	)

Attempts to assign a value to this non-vector Parameter from a string.

Parameters

str	String with which to populate this parameter.
poke	If true, does not increment write count.

Note: Interpretation of the string is handled by the subclass; Expected to use sparta::utils::smartLexicalCast to perform conversion

Postcondition: Increments write count if poke is false

Exceptions

ParameterException if the given string cannot be lexically converted or if parameter is a vector type (isVector() == true). cast to the internal parameter type.

◆ setValueFromStringImpl_()

		bool	poke = `false`
	)

protectedpure virtual

Implements setValueFromString.

◆ setValueFromStringVector()

void sparta::ParameterBase::setValueFromStringVector	(	const std::vector< std::string > &	str,
		bool	poke = `false`
	)

Attempts to assign a value to this vector Parameter from a string.

Parameters

str	Vector of strings with which to populate this Parameter.
poke	If true, does not increment write count.

Postcondition: Existing elements in the Parameter will be erased; Parameter will contain vector with elements and size equivalent to str, in the appropriate internal type.

Note: Interpretation of the string is handled by the subclass; Expected to use sparta::utils::smartLexicalCast to perform conversions

Postcondition: Increments write count if poke is false

Exceptions

ParameterException if the given string cannot be lexically converted or if parameter is a non-vector type (isVector() == false). cast to the internal parameter type.

inlineoverridevirtual

Render description of this parameter as a string.

Note: This is not only the value, but also a description of the parameter itself; Does not increment the read counter for this parameter

Returns

String description of the form

* (<type> "<name>" : <value>, def=<default> read: <read_count>)
*

◆ supportsCompression()

virtual bool sparta::ParameterBase::supportsCompression ( ) const

inlinevirtual

Scalar parameters may compress well, but we cannot really make a strong enough determination without knowing more about the parameter. Let's disable compression for these by default.

◆ unread_()

void sparta::ParameterBase::unread_ ( ) const

inlineprotected

Mark this parameter as unread and unignored This is used or preloading defaults to parameters and then clearing the write count. It is intended to be used by ParameterSet.

Implemented in sparta::Parameter< ValueType >.

◆ validateIndependently()

virtual bool sparta::ParameterBase::validateIndependently ( std::string & err_names ) const

pure virtual

Performs validation independently of all other Parameters.

Parameters

err_names String which will be appended with names of any failed validators.

Returns: false if any independent validators fail; true otherwise.

Postcondition: Appends to err_names a comma delimited list of any validators that failed.
