          Record... data)

Method Detail

getOrCreateRef

public static DSResponse getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

setJavaScriptObject

public void setJavaScriptObject(com.google.gwt.core.client.JavaScriptObject jsObj)

Overrides:

setJavaScriptObject in class RPCResponse

setDataSource

public void setDataSource(java.lang.String dataSource)

The DataSource of this DSResponse.

Parameters:

dataSource - . See String. Default value is null

getDataSource

public java.lang.String getDataSource()

The DataSource of this DSResponse.

Returns:

. See 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

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 - 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 - queueStatus

See Also:

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

See Also:

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:

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 - status
