Member Function Documentation

allocatedMemory()

size_t Aqua::InputOutput::Variables::allocatedMemory

(

)

Get the allocated memory.

Returns

Allocated memory on device. Just the arrays can contribute to this value.

exprVariables()

std::vector< Variable * > Aqua::InputOutput::Variables::exprVariables

(

const std::string &

expr

)

Get the list of variables called on a expression.

Parameters

expr	Expression to parse.

Returns

The list of input variables.

Aqua::Tokenizer::exprVariables()

Here is the call graph for this function:

get() [1/2]

Variable * Aqua::InputOutput::Variables::get

(

const std::string

name

)

Get a variable.

Parameters

name	Name of the variable.

Returns

Variable, NULL if the variable cannot be found.

get() [2/2]

Variable * Aqua::InputOutput::Variables::get

(

unsigned int

index

)

Get a variable.

Parameters

index

Index of the variable.

Returns

Variable, NULL if the variable cannot be found.

getAll()

std::vector< Variable * > Aqua::InputOutput::Variables::getAll ( ) const

inline

Get all the registered variables.

Returns

Variable, NULL if the variable cannot be found.

isSameType()

bool Aqua::InputOutput::Variables::isSameType ( const std::string type_a, const std::string type_b, bool ignore_asterisk = true )

static

Get if two types strings are the same one.

Parameters

type_a	First type name.
type_b	Second type name.
ignore_asterisk	true to ignore the asterisk of arrays.

Returns

true if it is the same type, false otherwise.

Here is the call graph for this function:

populate() [1/2]

void Aqua::InputOutput::Variables::populate

(

const std::string

name = ""

)

Populate variables in order that the tokenizer may get the updated value.

Parameters

name	Name of the variable to be populated, "" if all the variables should be populated.

Here is the call graph for this function:

populate() [2/2]

void Aqua::InputOutput::Variables::populate

(

Variable *

var

)

Populate a variable in order that the tokenizer may know the updated value.

Parameters

var	Variable to be populated.

Here is the call graph for this function:

registerVariable()

void Aqua::InputOutput::Variables::registerVariable	(	const std::string	name,
		const std::string	type,
		const std::string	length,
		const std::string	value )

Register a new variable.

Parameters

name	Name of the variable.
type	Type of the variable.
length	Array length, 1 for scalars, 0 for arrays that will not be allocated at the start (for instance the heads of chains, which requires the number of cells).
value	Variable value, NULL for arrays. It is optional for scalar variables.

size()

unsigned int Aqua::InputOutput::Variables::size ( ) const

inline

Get the number of variables.

Returns

Number of registered variables.

solve()

void Aqua::InputOutput::Variables::solve	(	const std::string	type_name,
		const std::string	value,
		void *	data,
		const std::string	name = "NULL" )

Solve a string, interpreting the variables.

Parameters

type_name	Type of the output desired value.
value	Expression to evaluate.
data	Allocated memory where the result should be stored.
name	Variable name to register in the tokenizer.

Note

typeToBytes(type) bytes should be allocated in data.

Here is the call graph for this function:

typeAlias()

std::string Aqua::InputOutput::Variables::typeAlias ( const std::string & t )

static

Resolve some type aliases.

Several types have aliases to make them easier to use, which might depend on the device arch:

• "int32" = "int"
• "int64" = "long"
• "uint32" = "unsigned int"
• "uint64" = "unsigned long"
• "size_t" = Either "unsigned int" or "unsigned long"
• "ssize_t" = Either "int" or "long"
• "svec" = Either "uivec" or "ulvec"
• "svec2" = Either "uivec2" or "ulvec2"
• "svec3" = Either "uivec3" or "ulvec3"
• "svec4" = Either "uivec4" or "ulvec4"
• "svec8" = Either "uivec8" or "ulvec8"
• "ssvec" = Either "ivec" or "lvec"
• "ssvec2" = Either "ivec2" or "lvec2"
• "ssvec3" = Either "ivec3" or "lvec3"
• "ssvec4" = Either "ivec4" or "lvec4"
• "ssvec8" = Either "ivec8" or "lvec8"

  Parameters

  t	Input aliased type

  Returns

  Base type

  Aqua::CalcServer::CalcServer::device_addr_bits()

Here is the call graph for this function:

typeToBytes()

size_t Aqua::InputOutput::Variables::typeToBytes ( const std::string type )

static

Convert a type name to bytes.

Parameters

type	Type name.

Returns

Type size in bytes, 0 if the type is not recognized.

Here is the call graph for this function:

typeToN()

unsigned int Aqua::InputOutput::Variables::typeToN ( const std::string type )

static

Get the number of components of a type name.

Parameters

type	Type name.

Returns

Number of components (1 for not recognized types).
