Detailed Description

A Struct has a StructSet as its parent.

It contains the field values returned after executing a Query obtained from a QueryService which in turn is obtained from a Cache.

◆ createDeserializable()

static std::shared_ptr< Serializable > apache::geode::client::Struct::createDeserializable ( )

static

Factory function for registration of Struct.

◆ getFieldName()

virtual const std::string & apache::geode::client::Struct::getFieldName ( const int32_t index ) const

virtual

Returns the name of the field corresponding to the index number in the Struct.

Exceptions

std::out_of_range if index is not found

◆ getStructSet()

const std::shared_ptr< StructSet > apache::geode::client::Struct::getStructSet ( ) const

Get the parent StructSet of this Struct.

Returns: A smart pointer to the parent StructSet of this Struct.

◆ objectSize()

size_t apache::geode::client::Struct::objectSize ( ) const

inlineoverride

always returns 0

◆ operator[]() [1/2]

const std::shared_ptr< Serializable > apache::geode::client::Struct::operator[] ( const std::string & fieldName ) const

Get the field value for the given field name.

Parameters

fieldName the name of the field whos value is required.

Returns: A smart pointer to the field value.

Exceptions

IllegalArgumentException if the field name is not found.

◆ operator[]() [2/2]

const std::shared_ptr< Serializable > apache::geode::client::Struct::operator[] ( int32_t index ) const

Get the field value for the given index number.

Parameters

index the index number of the field value to get.

Returns: A smart pointer to the field value or nullptr if index out of bounds.

◆ size()

int32_t apache::geode::client::Struct::size ( ) const

Get the number of field values available.

Returns: the number of field values available.
