Definition at line 959 of file sharedVector.h.

getScalarType()

ScalarType epics::pvData::ScalarTypeFunc::getScalarType ( std::string const & value )

extern

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()

bool epics::pvData::ScalarTypeFunc::isInteger ( ScalarType scalarType )

extern

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()

bool epics::pvData::ScalarTypeFunc::isNumeric ( ScalarType scalarType )

extern

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()

bool epics::pvData::ScalarTypeFunc::isPrimitive ( ScalarType scalarType )

extern

Is the type primitive, i.e. not string

Parameters

scalarType

The type.

Returns

(false,true) if the scalarType is primitive.

isUInteger()

bool epics::pvData::ScalarTypeFunc::isUInteger ( ScalarType scalarType )

extern

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()

const char * epics::pvData::ScalarTypeFunc::name ( ScalarType scalarType )

extern

Get a name for the scalarType.

Parameters

scalarType

The type.

Returns

The name for the scalarType.
