Classes

TnxBaseBlobStream

Base class for NexusDB blob streams.

Never create instances directly! Always use TnxDataSet.CreateBlobStream, which will create the right type of blob stream based on the state of the dataset.

The blob stream should be freed again as soon as possible. It must be freed before calling Post or moving to another record.

TnxBaseSession

The mother of all sessions. It implements a component that is used the same way as Borland's TSession and adds some features unique to NexusDB.

TnxBatchAppendBlobStream

This class is used if the dataset is in batch append mode.

Never create instances directly! Always use TnxDataSet.CreateBlobStream, which will create the right type of blob stream based on the state of the dataset.

The blob stream should be freed again as soon as possible. It must be freed before calling Post or moving to another record.

TnxBlobStream

This class is used to access a blob directly. All calls are directly passed through to the server engine.

Never create instances directly! Always use TnxDataSet.CreateBlobStream, which will create the right type of blob stream based on the state of the dataset.

The blob stream should be freed again as soon as possible. It must be freed before calling Post or moving to another record.

TnxBlockModeBlobStream

This class is used if the dataset is in block read mode.

Never create instances directly! Always use TnxDataSet.CreateBlobStream, which will create the right type of blob stream based on the state of the dataset.

The blob stream should be freed again as soon as possible. It must be freed before calling Post or moving to another record.

TnxCursor

Client-side Cursor class.

TnxDataAccessStateComponent

The base class for all client side data components

TnxDatabase

Implementation of a TDatabase similar component.

TnxDataset

TnxDataset is the base class for all TDataset compatible Nexus components. Most methods and properties work exactly the same as Borland's implementation.

TnxIndexDataSet

TnxIndexDataSet adds support for indexing to TnxDataset.

TnxKeyAsVariantField

The text for this class has been generated automatically. This means that it is not documented.

TnxQuery

TnxSession

A BDE compatible implementation of a NexusDB session.

TnxStatementDataSet

TQuery compatible implementation of a Nexus SQL Query

TnxStatementDataSetDataLink

Used internally by the query, if you set TnxStatementDataSet.DataSource. This object is used to manage that link.

TnxStoredProc

The text for this class has been generated automatically. This means that it is not documented.

TnxTable

TnxTable is a TTable compatible implementation of a NexusDB dataset.
