Constructor Detail

DSResponse

public DSResponse()

DSResponse

public DSResponse(JavaScriptObject jsObj)

DSResponse

public DSResponse(java.lang.String dataSource)

DSResponse

public DSResponse(java.lang.String dataSource,
          DSOperationType operationType)

DSResponse

public DSResponse(java.lang.String dataSource,
          DSOperationType operationType,
          Record... data)

Method Detail

getOrCreateRef

public static DSResponse getOrCreateRef(JavaScriptObject jsObj)

getData

public Record[] getData()

For "fetch" operations, this is the array of Records fetched. For "update", "add", and "remove" operations, this is typically an array containing a single Record representing the record that was updated, added, or removed.

Returns:

Record...

getDataAsRecordList

public RecordList getDataAsRecordList()

For "fetch" operations, this is the array of Records fetched. For "update", "add", and "remove" operations, this is typically an array containing a single Record representing the record that was updated, added, or removed.

Returns:

RecordList

setDataSource

public void setDataSource(java.lang.String dataSource)

The DataSource of this DSResponse.

Parameters:

dataSource - Default value is null

getDataSource

public java.lang.String getDataSource()

The DataSource of this DSResponse.

Returns:

String

getEndRow

public java.lang.Integer getEndRow()

End row of returned server results, when using paged result fetching

Note that startRow and endRow are zero-based - the first record is row zero.

Returns:

Integer

getFromOfflineCache

public java.lang.Boolean getFromOfflineCache()

If set, indicates that this response came from the offline cache, not the server. This flag is the only reliable way for application code to determine the source of a response.

Returns:

Boolean

getHttpHeaders

public java.util.Map getHttpHeaders()

HTTP headers returned by the server as a map from header name to header value.

Headers are available only when the default RPCTransport "xmlHttpRequest" is in use, and browsers may limit access to headers for cross-domain requests or in other security-sensitive scenarios.

Overrides:

getHttpHeaders in class RPCResponse

Returns:

Map

getInvalidateCache

public java.lang.Boolean getInvalidateCache()

Optional flag that can be set by the server to force ResultSets to drop any caches of records from the DataSource that was the target of the operation.

Returns:

Boolean

getOfflineTimestamp

public java.lang.Integer getOfflineTimestamp()

Timestamp (millisecond value) to indicate when this dsResponse was cached in offline storage. Not applicable if the response has never been stored offline.

Returns:

Integer

setOperationType

public void setOperationType(DSOperationType operationType)

The operation type of the request corresponding to this DSResponse.

Parameters:

operationType - Default value is null

getOperationType

public DSOperationType getOperationType()

The operation type of the request corresponding to this DSResponse.

Returns:

DSOperationType

setQueueStatus

public void setQueueStatus(int queueStatus)

An extra property of each DSResponse to a queued request that indicates whether the queue as a whole succeeded. A queueStatus of STATUS_SUCCESS, or 0, indicates that the queue succeeded whereas a queueStatus of STATUS_FAILURE, or -1, indicates that the queue failed.

For example, if two "update" requests are sent in a queue and the first succeeded, but the second failed validation, then both DSResponses' queueStatus would be -1, but the status of the first would be STATUS_SUCCESS and the status of the second would be an error code such as STATUS_VALIDATION_ERROR.

Parameters:

queueStatus - Default value is see below

ErrorHandling overview and related methods

getQueueStatus

public int getQueueStatus()

An extra property of each DSResponse to a queued request that indicates whether the queue as a whole succeeded. A queueStatus of STATUS_SUCCESS, or 0, indicates that the queue succeeded whereas a queueStatus of STATUS_FAILURE, or -1, indicates that the queue failed.

For example, if two "update" requests are sent in a queue and the first succeeded, but the second failed validation, then both DSResponses' queueStatus would be -1, but the status of the first would be STATUS_SUCCESS and the status of the second would be an error code such as STATUS_VALIDATION_ERROR.

Returns:

int

ErrorHandling overview and related methods

getStartRow

public java.lang.Integer getStartRow()

Starting row of returned server results, when using paged result fetching

Note that startRow and endRow are zero-based - the first record is row zero.

Returns:

Integer

setStatus

public void setStatus(int status)

Same meaning as status, except DSResponses have additional error codes, such as validation failure.

Overrides:

setStatus in class RPCResponse

Parameters:

status - Default value is see below

See Also:

ErrorHandling overview and related methods

getStatus

public int getStatus()

Same meaning as status, except DSResponses have additional error codes, such as validation failure.

Overrides:

getStatus in class RPCResponse

Returns:

int

See Also:

ErrorHandling overview and related methods

setStartRow

public void setStartRow(java.lang.Integer startRow)

Starting row of returned server results, when using paged result fetching

Note that startRow and endRow are zero-based - the first record is row zero.

Parameters:

startRow - the start row

setEndRow

public void setEndRow(java.lang.Integer endRow)

End row of returned server results, when using paged result fetching

Note that startRow and endRow are zero-based - the first record is row zero.

Parameters:
