func (QueueServiceClient) ClearMessages 

func (c QueueServiceClient) ClearMessages(queue string) error

ClearMessages operation deletes all messages from the specified queue.

See https://msdn.microsoft.com/en-us/library/azure/dd179454.aspx

func (QueueServiceClient) CreateQueue 

func (c QueueServiceClient) CreateQueue(name string) error

CreateQueue operation creates a queue under the given account.

See https://msdn.microsoft.com/en-us/library/azure/dd179342.aspx

func (QueueServiceClient) DeleteMessage 

func (c QueueServiceClient) DeleteMessage(queue, messageID, popReceipt string) error

DeleteMessage operation deletes the specified message.

See https://msdn.microsoft.com/en-us/library/azure/dd179347.aspx

func (QueueServiceClient) DeleteQueue 

func (c QueueServiceClient) DeleteQueue(name string) error

DeleteQueue operation permanently deletes the specified queue.

See https://msdn.microsoft.com/en-us/library/azure/dd179436.aspx

func (QueueServiceClient) GetMessages 

func (c QueueServiceClient) GetMessages(queue string, params GetMessagesParameters) (GetMessagesResponse, error)

GetMessages operation retrieves one or more messages from the front of the queue.

See https://msdn.microsoft.com/en-us/library/azure/dd179474.aspx

func (QueueServiceClient) GetMetadata 

func (c QueueServiceClient) GetMetadata(name string) (QueueMetadataResponse, error)

GetMetadata operation retrieves user-defined metadata and queue properties on the specified queue. Metadata is associated with the queue as name-values pairs.

See https://msdn.microsoft.com/en-us/library/azure/dd179384.aspx

Because the way Golang's http client (and http.Header in particular) canonicalize header names, the returned metadata names would always be all lower case.

func (QueueServiceClient) PeekMessages 

func (c QueueServiceClient) PeekMessages(queue string, params PeekMessagesParameters) (PeekMessagesResponse, error)

PeekMessages retrieves one or more messages from the front of the queue, but does not alter the visibility of the message.

See https://msdn.microsoft.com/en-us/library/azure/dd179472.aspx

func (QueueServiceClient) PutMessage 

func (c QueueServiceClient) PutMessage(queue string, message string, params PutMessageParameters) error

PutMessage operation adds a new message to the back of the message queue.

See https://msdn.microsoft.com/en-us/library/azure/dd179346.aspx

func (QueueServiceClient) QueueExists 

func (c QueueServiceClient) QueueExists(name string) (bool, error)

QueueExists returns true if a queue with given name exists.

func (QueueServiceClient) SetMetadata 

func (c QueueServiceClient) SetMetadata(name string, metadata map[string]string) error

SetMetadata operation sets user-defined metadata on the specified queue. Metadata is associated with the queue as name-value pairs.

See https://msdn.microsoft.com/en-us/library/azure/dd179348.aspx

type TableEntity 

type TableEntity interface {
	PartitionKey() string
	RowKey() string
	SetPartitionKey(string) error
	SetRowKey(string) error
}

TableEntity interface specifies the functions needed to support marshaling and unmarshaling into Azure Tables. The struct must only contain simple types because Azure Tables do not support hierarchy.

type TableServiceClient 

type TableServiceClient struct {
	// contains filtered or unexported fields
}

TableServiceClient contains operations for Microsoft Azure Table Storage Service.

func (*TableServiceClient) CreateTable 

func (c *TableServiceClient) CreateTable(table AzureTable) error

CreateTable creates the table given the specific name. This function fails if the name is not compliant with the specification or the tables already exists.

func (*TableServiceClient) DeleteEntity 

func (c *TableServiceClient) DeleteEntity(table AzureTable, entity TableEntity, ifMatch string) error

DeleteEntity deletes the entity matching by PartitionKey, RowKey and ifMatch field. The function fails if there is no entity with the same PartitionKey and RowKey in the table or the ifMatch is different.

func (*TableServiceClient) DeleteEntityWithoutCheck 

func (c *TableServiceClient) DeleteEntityWithoutCheck(table AzureTable, entity TableEntity) error

DeleteEntityWithoutCheck deletes the entity matching by PartitionKey and RowKey. There is no check on IfMatch parameter so the entity is always deleted. The function fails if there is no entity with the same PartitionKey and RowKey in the table.

func (*TableServiceClient) DeleteTable 

func (c *TableServiceClient) DeleteTable(table AzureTable) error

DeleteTable deletes the table given the specific name. This function fails if the table is not present. Be advised: DeleteTable deletes all the entries that may be present.

func (*TableServiceClient) InsertEntity 

func (c *TableServiceClient) InsertEntity(table AzureTable, entity TableEntity) error

InsertEntity inserts an entity in the specified table. The function fails if there is an entity with the same PartitionKey and RowKey in the table.

func (*TableServiceClient) InsertOrMergeEntity 

func (c *TableServiceClient) InsertOrMergeEntity(table AzureTable, entity TableEntity) error

InsertOrMergeEntity inserts an entity in the specified table or merges the existing one.

func (*TableServiceClient) InsertOrReplaceEntity 

func (c *TableServiceClient) InsertOrReplaceEntity(table AzureTable, entity TableEntity) error

InsertOrReplaceEntity inserts an entity in the specified table or replaced the existing one.

func (*TableServiceClient) MergeEntity 

func (c *TableServiceClient) MergeEntity(table AzureTable, entity TableEntity) error

MergeEntity merges the contents of an entity with the one passed as parameter. The function fails if there is no entity with the same PartitionKey and RowKey in the table.

func (*TableServiceClient) QueryTableEntities 

func (c *TableServiceClient) QueryTableEntities(tableName AzureTable, previousContToken *ContinuationToken, retType reflect.Type, top int, query string) ([]TableEntity, *ContinuationToken, error)

QueryTableEntities queries the specified table and returns the unmarshaled entities of type retType. top parameter limits the returned entries up to top. Maximum top allowed by Azure API is 1000. In case there are more than top entries to be returned the function will return a non nil *ContinuationToken. You can call the same function again passing the received ContinuationToken as previousContToken parameter in order to get the following entries. The query parameter is the odata query. To retrieve all the entries pass the empty string. The function returns a pointer to a TableEntity slice, the *ContinuationToken if there are more entries to be returned and an error in case something went wrong.

Example: 

entities, cToken, err = tSvc.QueryTableEntities("table", cToken, reflect.TypeOf(entity), 20, "")

func (*TableServiceClient) QueryTables 

func (c *TableServiceClient) QueryTables() ([]AzureTable, error)

QueryTables returns the tables created in the *TableServiceClient storage account.

func (*TableServiceClient) UpdateEntity 

func (c *TableServiceClient) UpdateEntity(table AzureTable, entity TableEntity) error

UpdateEntity updates the contents of an entity with the one passed as parameter. The function fails if there is no entity with the same PartitionKey and RowKey in the table.

type UnexpectedStatusCodeError 

type UnexpectedStatusCodeError struct {
	// contains filtered or unexported fields
}

UnexpectedStatusCodeError is returned when a storage service responds with neither an error nor with an HTTP status code indicating success.

func (UnexpectedStatusCodeError) Error 

func (e UnexpectedStatusCodeError) Error() string

func (UnexpectedStatusCodeError) Got 

func (e UnexpectedStatusCodeError) Got() int

Got is the actual status code returned by Azure.
