Member Function Documentation

void allocate_data_from_scratch	(	index_t	len_y,
		index_t	len_x,
		bool	new_cont_call = true
	)

Allocates data for this instance from scratch. This is one of the core methods in parameter migration. It is used if parameters have to be loaded from file without having a class instance to put the data into. Namely, the data length variables are allocated, for numeric scalars, the memory is allocated, for SG_OBJECT scalars, a pointer to an CSGObject is allocated, for non-scalars, the pointer to the data is allocated for non-scalars, the actual data is also allocated via cont_new()

Parameters

len_y	desired y length of the data
len_x	desired x length of the data
new_cont_call	whether new_cont should be called, if false, only scalar non-sgobject data will be allocated (needed for migration)

Definition at line 2676 of file Parameter.cpp.

void copy_data

(

const TParameter *

source

)

Given another TParameter instance (with same type, except for lengths) all its data is copied to the current one. This means in case of numeric scalars that the value is copied and in SG_OBJECT scalars and any arrays that the pointer to the data is copied. The old data is overwritten. Old SG_OBJECTS are SG_UNREF'ed and the new ones are SG_REF'ed.

Parameters

source

source TParameter instance to copy from

void get_incremental_hash	(	uint32_t &	hash,
		uint32_t &	carry,
		uint32_t &	total_length
	)

Incrementally get a hash from parameter value*

Parameters

hash	current hash value
carry	value for incremental murmur hashing
total_length	byte length of parameters. Function will add byte length to received value

Definition at line 2192 of file Parameter.cpp.

bool load	(	CSerializableFile *	file,
		const char *	prefix = ""
	)

load from serializable file

Parameters

file	source file
prefix	prefix

Definition at line 2357 of file Parameter.cpp.

bool operator<

(

const TParameter &

other

)

const

operator for comparison (by string m_name)

Definition at line 2666 of file Parameter.cpp.

bool operator==

(

const TParameter &

other

)

const

operator for comparison, (by string m_name)

Definition at line 2659 of file Parameter.cpp.

bool operator>

(

const TParameter &

other

)

const

operator for comparison (by string m_name)

Definition at line 2671 of file Parameter.cpp.

void print

(

const char *

prefix

)

print with prefix

Parameters

prefix

prefix to print

Definition at line 1634 of file Parameter.cpp.

bool save	(	CSerializableFile *	file,
		const char *	prefix = ""
	)

save to serializable file

Parameters

file	destination file
prefix	prefix

Member Data Documentation

TSGDataType m_datatype

type of parameter

Definition at line 90 of file Parameter.h.

bool m_delete_data

if this is set true, the data, m_parameter points to, m_parameter itself, and possible lengths of the type will be deleted in destructor. This is needed because in data migration, TParameter instances are created from scratch without having a class instance and allocated data has to ne deleted in this case. The only way to set this is via an alternate constructor, false by default

Definition at line 105 of file Parameter.h.

char* m_description

description of parameter

Definition at line 96 of file Parameter.h.

char* m_name

name of parameter

Definition at line 94 of file Parameter.h.

void* m_parameter

pointer to parameter

Definition at line 92 of file Parameter.h.

bool m_was_allocated_from_scratch

Returns

true if data was not allocated by a class which registered its parameter, but from scratch using allocate_data_from_scratch
