A ReaderQuery encapsulates the various ways that an application can search for data to read or take from a DataReader.

| ReaderQuery | ( | const ::dds::sub::status::ReaderState & | src | ) | [inline] |
Construct a query to read or take samples of all available instances that have the given ReaderState.
Definition at line 72 of file ReaderQuery.hpp.
| ReaderQuery | ( | const ReadCondition & | src | ) | [inline] |
Construct a query to read or take samples of all available instances, the availability of which would cause the given ReadCondition or QueryCondition to trigger.
Definition at line 84 of file ReaderQuery.hpp.
| ReaderQuery | ( | const ::dds::core::InstanceHandle & | src, | |
| bool | read_or_take_next = false | |||
| ) | [inline] |
Construct a query to read or take samples of the identified instance (or the "next" instance), regardless of ReaderState.
| read_or_take_next | If this flag is set to false (the default), the read or take will return samples of the identified instance. If it is true, the read or take will return samples of the "next" instance in order. This behavior allows applications to easily iterate over the available data one instance at a time. |

| const ::dds::core::InstanceHandle & | handle, | |||
| bool | read_or_take_next = false | |||
| ) | [inline] |
Construct a query to read or take samples of the identified instance (or the "next" instance) and with the given ReaderState.
| read_or_take_next | If this flag is set to false (the default), the read or take will return samples of the identified instance. If it is true, the read or take will return samples of the "next" instance in order. This behavior allows applications to easily iterate over the available data one instance at a time. |

| ReaderQuery | ( | const ReadCondition & | cond, | |
| const ::dds::core::InstanceHandle & | handle, | |||
| bool | read_or_take_next = false | |||
| ) | [inline] |
Construct a query to read or take samples of the identified instance, the availability of which would cause the given ReadCondition or QueryCondition to trigger.
| read_or_take_next | If this flag is set to false (the default), the read or take will return samples of the identified instance. If it is true, the read or take will return samples of the "next" instance in order. This behavior allows applications to easily iterate over the available data one instance at a time. |
Definition at line 145 of file ReaderQuery.hpp.
| ReadCondition condition | ( | ) | const [inline] |
The application intends only to read or take those samples, the availability of which would cause the given ReadCondition or QueryCondition to trigger.
Definition at line 194 of file ReaderQuery.hpp.
| const dds::core::InstanceHandle instance | ( | ) | const [inline] |
If this method returns a non-nil handle, the application intends to read or take only those samples pertaining to the given instance (or the "next" instance). If it returns a nil handle, the application intends to read or take samples pertaining to all available instances.
Definition at line 162 of file ReaderQuery.hpp.
| bool is_read_or_take_next | ( | ) | const [inline] |
If this flag is set to false, the read or take will return samples of the identified instance. If it is true, the read or take will return samples of the "next" instance in order. This behavior allows applications to easily iterate over the available data one instance at a time.

| const dds::sub::status::ReaderState reader_state | ( | ) | const [inline] |
The application intends to read or take only those samples with the given ReaderState.
If this ReaderQuery was initialized with a ReadCondition or QueryCondition, this method shall return the ReaderState associated with that condition.
