Detailed Description

A StructSet may be obtained after executing a Query which is obtained from a QueryService which in turn is obtained from a Cache.

It is the parent of a Struct which contains the field values.

Member Function Documentation

virtual Iterator apache::geode::client::SelectResults::begin ( ) const

pure virtualinherited

Get an iterator pointing to the start of vector.

virtual Iterator apache::geode::client::SelectResults::end ( ) const

pure virtualinherited

Get an iterator pointing to the end of vector.

virtual int32_t apache::geode::client::StructSet::getFieldIndex ( const char *  fieldname )

pure virtual

Get the index number of the specified field name in the StructSet.

Parameters

fieldname

the field name for which the index is required.

Returns

the index number of the specified field name.

Exceptions

IllegalArgumentException

if the field name is not found.

virtual const char* apache::geode::client::StructSet::getFieldName ( int32_t  index )

pure virtual

Get the field name of the StructSet from the specified index number.

Parameters

index

the index number of the field name to get.

Returns

the field name from the specified index number or NULL if not found.

virtual SelectResultsIterator apache::geode::client::StructSet::getIterator ( )

pure virtual

Get a SelectResultsIterator with which to iterate over the items in the StructSet.

Returns

The SelectResultsIterator with which to iterate.

Implements apache::geode::client::SelectResults.

virtual bool apache::geode::client::StructSet::isModifiable ( ) const

pure virtual

Check whether the StructSet is modifiable.

Returns

false always at this time.

Implements apache::geode::client::SelectResults.

virtual const SerializablePtr apache::geode::client::StructSet::operator[] ( int32_t  index ) const

pure virtual

Index operator to directly access an item in the StructSet.

Parameters

index

the index number of the item to get.

Exceptions

IllegalArgumentException

if the index is out of bounds.

Returns

A smart pointer to the item indexed.

Implements apache::geode::client::SelectResults.

void apache::geode::client::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t apache::geode::client::SharedBase::refCount ( )

inlineinherited

Returns

the reference count

void apache::geode::client::SharedBase::releaseSB ( ) const

inherited

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.

virtual int32_t apache::geode::client::StructSet::size ( ) const

pure virtual

Get the size of the StructSet.

Returns

the number of items in the StructSet.

Implements apache::geode::client::SelectResults.
