Detailed Description

Interface for in-line creating of introspection interfaces.

One instance can be used to create multiple Field instances. An instance of this object must not be used concurrently (an object has a state).

add() [1/2]

FieldBuilderPtr epics::pvData::FieldBuilder::add	(	std::string const &	name,
		ScalarType	scalarType
	)

Add a Scalar.

Parameters

name	name of the array.
scalarType	type of a scalar to add.

Returns

this instance of a FieldBuilder.

add() [2/2]

FieldBuilderPtr epics::pvData::FieldBuilder::add	(	std::string const &	name,
		FieldConstPtr const &	field
	)

Add a Field (e.g. Structure, Union).

Parameters

name	name of the array.
field	a field to add.

Returns

this instance of a FieldBuilder.

addArray() [1/2]

FieldBuilderPtr epics::pvData::FieldBuilder::addArray	(	std::string const &	name,
		ScalarType	scalarType
	)

Add variable size array of Scalar elements.

Parameters

name	name of the array.
scalarType	type of a scalar element.

Returns

this instance of a FieldBuilder.

addArray() [2/2]

FieldBuilderPtr epics::pvData::FieldBuilder::addArray	(	std::string const &	name,
		FieldConstPtr const &	element
	)

Add array of Field elements.

Parameters

name	name of the array.
element	a type of an array element.

Returns

addBoundedArray()

FieldBuilderPtr epics::pvData::FieldBuilder::addBoundedArray	(	std::string const &	name,
		ScalarType	scalarType,
		std::size_t	bound
	)

Add bounded-size array of Scalar elements.

Parameters

name	name of the array.
scalarType	type of a scalar element.
bound	Array maximum capacity (size).

Returns

this instance of a FieldBuilder.

addBoundedString()

FieldBuilderPtr epics::pvData::FieldBuilder::addBoundedString	(	std::string const &	name,
		std::size_t	maxLength
	)

Add a BoundedString.

Parameters

name	name of the array.
maxLength	a string maximum length.

Returns

this instance of a FieldBuilder.

addFixedArray()

FieldBuilderPtr epics::pvData::FieldBuilder::addFixedArray	(	std::string const &	name,
		ScalarType	scalarType,
		std::size_t	size
	)

Add fixed-size array of Scalar elements.

Parameters

name	name of the array.
scalarType	type of a scalar element.
size	Array fixed size.

Returns

this instance of a FieldBuilder.

addNestedStructure()

FieldBuilderPtr epics::pvData::FieldBuilder::addNestedStructure

(

std::string const &

name

)

Add new nested Structure. endNested() method must be called to complete creation of the nested Structure.

Parameters

name	nested structure name.

Returns

a new instance of a FieldBuilder is returned.

endNested()

addNestedStructureArray()

FieldBuilderPtr epics::pvData::FieldBuilder::addNestedStructureArray

(

std::string const &

name

)

Add new nested Structure[]. endNested() method must be called to complete creation of the nested Structure.

Parameters

name	nested structure name.

Returns

a new instance of a FieldBuilder is returned.

See also

endNested()

addNestedUnion()

FieldBuilderPtr epics::pvData::FieldBuilder::addNestedUnion

(

std::string const &

name

)

Add new nested Union. endNested() method must be called to complete creation of the nested Union.

Parameters

name	nested union name.

Returns

a new instance of a FieldBuilder is returned.

See also

endNested()

addNestedUnionArray()

FieldBuilderPtr epics::pvData::FieldBuilder::addNestedUnionArray

(

std::string const &

name

)

Add new nested Union[]. endNested() method must be called to complete creation of the nested Union.

Parameters

name	nested union name.

Returns

a new instance of a FieldBuilder is returned.

endNested()

begin()

static FieldBuilderPtr epics::pvData::FieldBuilder::begin ( )

static

Create a new instance of in-line Field builder.

Version

Added after 7.0.0

createStructure()

StructureConstPtr epics::pvData::FieldBuilder::createStructure

(

)

Create a Structure. This resets this instance state and allows new Field instance to be created.

Returns

a new instance of a Structure.

createUnion()

UnionConstPtr epics::pvData::FieldBuilder::createUnion

(

)

Create an Union. This resets this instance state and allows new Field instance to be created.

Returns

a new instance of an Union.

endNested()

FieldBuilderPtr epics::pvData::FieldBuilder::endNested

(

)

Complete the creation of a nested object.

See also

addNestedStructure(std::string const & name)

addNestedUnion(std::string const & name)

Returns

a previous (parent) FieldBuilder.

setId()

FieldBuilderPtr epics::pvData::FieldBuilder::setId

(

std::string const &

id

)

Set ID of an object to be created.

Parameters

id	id to be set.

Returns

this instance of a FieldBuilder.
