Detailed Description

Hold a parameter value for an "aperture macro" as defined within standard RS274X.

The parameter can be a constant, i.e. "immediate" parameter, or depend on some deferred values, defined in a D_CODE, by the ADD command. Note the actual value could need an evaluation from an arithmetical expression items in the expression are stored in. A simple definition is just a value stored in one item in m_paramStack.

◆ IsImmediate()

bool AM_PARAM::IsImmediate ( ) const

Test if this AM_PARAM holds an immediate parameter or is a pointer into a parameter held by an owning D_CODE.

Function IsImmediate tests if this AM_PARAM holds an immediate parameter or has parameter held by an owning D_CODE.

Returns: true if the value is immediate, i.e. no deferred value in operands used in its definition.

◆ PushOperator() [1/2]

void AM_PARAM::PushOperator	(	parm_item_type	aType,
		double	aValue )

Add an operator/operand to the current stack.

add an operator/operand to the current stack aType = NOP, PUSHVALUE, PUSHPARM, ADD, SUB, MUL, DIV, EQUATE aValue required only for PUSHVALUE (double) or PUSHPARM (int) aType.

Parameters

aType	is the type of item (NOP, PUSHVALUE, PUSHPARM, ADD, SUB, MUL, DIV, EQUATE)
aValue	is the item value, double for PUSHVALUE or int for PUSHPARM type.

◆ ReadParamFromAmDef()

bool AM_PARAM::ReadParamFromAmDef ( char *& aText )

Read one aperture macro parameter.

Function ReadParam Read one aperture macro parameter a parameter can be: a number a reference to an aperture definition parameter value: $1 ot $3 ... a parameter definition can be complex and have operators between numbers and/or other parameter like $1+3 or $2x2.

a parameter can be: a number a reference to an aperture definition parameter value: $1 to $3 ... a parameter definition can be complex and have operators between numbers and/or other parameter like $1+3 or $2x2.. Parameters are separated by a comma ( of finish by *)

Parameters

aText = pointer to the parameter to read. Will be modified to point to the next field

Returns: true if a param is read, or false

Note minus sign is not always an operator. It can be the sign of a value. Parameters are separated by a comma ( of finish by *)

Parameters

aText = pointer to the parameter to read. Will be modified to point to the next field

Returns: true if a param is read, or false
