getScalarType()

epicsShareExtern ScalarType epics::pvData::ScalarTypeFunc::getScalarType

(

std::string const &

value

)

Get the scalarType for value.

Parameters

value

The name of the scalar type.

Returns

The scalarType. An exception is thrown if the name is not the name of a scalar type.

isInteger()

epicsShareExtern bool epics::pvData::ScalarTypeFunc::isInteger

(

ScalarType

scalarType

)

Is the type an integer, i.e. is it one of byte,...ulong

Parameters

scalarType

The type.

Returns

(false,true) if the scalarType is an integer.

isNumeric()

epicsShareExtern bool epics::pvData::ScalarTypeFunc::isNumeric

(

ScalarType

scalarType

)

Is the type numeric, i.e. is it one of byte,...,double

Parameters

scalarType

The type.

Returns

(false,true) if the scalarType is a numeric

isPrimitive()

epicsShareExtern bool epics::pvData::ScalarTypeFunc::isPrimitive

(

ScalarType

scalarType

)

Is the type primitive, i.e. not string

Parameters

scalarType

The type.

Returns

(false,true) if the scalarType is primitive.

isUInteger()

epicsShareExtern bool epics::pvData::ScalarTypeFunc::isUInteger

(

ScalarType

scalarType

)

Is the type an unsigned integer, i.e. is it one of ubyte,...ulong

Parameters

scalarType

The type.

Returns

(false,true) if the scalarType is an integer.

name()

epicsShareExtern const char* epics::pvData::ScalarTypeFunc::name

(

ScalarType

scalarType

)

Get a name for the scalarType.

Parameters

scalarType

The type.

Returns

The name for the scalarType.
