Constructor Detail

BlobRequestOptions

public BlobRequestOptions()

Creates an instance of the BlobRequestOptions class.

BlobRequestOptions

public BlobRequestOptions(BlobRequestOptions other)

Creates an instance of the BlobRequestOptions class by copying values from another BlobRequestOptions instance.

Parameters:

other - A BlobRequestOptions object which represents the blob request options to copy.

Method Detail

getAbsorbConditionalErrorsOnRetry

public Boolean getAbsorbConditionalErrorsOnRetry()

Indicates whether a conditional failure should be absorbed on a retry attempt for the request. For more information about absorb conditinal errors on retry defaults, see setAbsorbConditionalErrorsOnRetry(Boolean).

Returns:

the absorbConditionalErrorsOnRetry

getConcurrentRequestCount

public Integer getConcurrentRequestCount()

Gets the concurrent number of simultaneous requests per operation. For more information about concurrent request count defaults, see setConcurrentRequestCount(Integer).

Returns:

the concurrentRequestCount

getUseTransactionalContentMD5

public Boolean getUseTransactionalContentMD5()

Gets whether a range PUT or GET operation will use the Content-MD5 header to enforce transactional security. All partial blob uploads or downloads will be restricted to 4 MB. For more information about transactional content MD5 defaults, see setUseTransactionalContentMD5(Boolean).

Returns:

the useTransactionalContentMD5

getStoreBlobContentMD5

public Boolean getStoreBlobContentMD5()

Gets whether the blob's ContentMD5 header should be set on uploads. This field is not supported for page blobs. For more information about storing blob content MD5 defaults, see setStoreBlobContentMD5(Boolean) .

Returns:

the storeBlobContentMD5

getDisableContentMD5Validation

public Boolean getDisableContentMD5Validation()

Gets whether download and BlobInputStream methods should ignore the blob's ContentMD5 header. For more information about disabling content MD5 validation defaults, see setDisableContentMD5Validation(Boolean) .

Returns:

the disableContentMD5Validation

getSingleBlobPutThresholdInBytes

public Integer getSingleBlobPutThresholdInBytes()

Gets the threshold size used for writing a single blob. For more information about the threshold size defaults, see setSingleBlobPutThresholdInBytes(Integer).

Returns:

The maximum size, in bytes, of a blob that may be uploaded as a single blob, ranging from 1 to 64 MB inclusive. If a blob size is above the threshold, it will be uploaded as blocks.

setAbsorbConditionalErrorsOnRetry

public void setAbsorbConditionalErrorsOnRetry(Boolean absorbConditionalErrorsOnRetry)

Sets whether a conditional failure should be absorbed on a retry attempt for the request. This option is only used by CloudAppendBlob in upload and openWrite methods. By default, it is set to false. Set this to true only for single writer scenario.

You can change the absorbConditionalErrorsOnRetry value on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that absorbConditionalErrorsOnRetry value.

Parameters:

absorbConditionalErrorsOnRetry - the absorbConditionalErrorsOnRetry to set

setConcurrentRequestCount

public void setConcurrentRequestCount(Integer concurrentRequestCount)

Sets the concurrent number of simultaneous requests per operation.

The default concurrent request count is set in the client and is by default 1, indicating no concurrency. You can change the concurrent request count on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that concurrent request count.

Parameters:

concurrentRequestCount - the concurrentRequestCount to set

setUseTransactionalContentMD5

public void setUseTransactionalContentMD5(Boolean useTransactionalContentMD5)

Sets whether a range PUT or GET operation will use the Content-MD5 header to enforce transactional security. All partial blob uploads or downloads will be restricted to 4 MB.

The default useTransactionalContentMD5 value is set in the client and is by default false. You can change the useTransactionalContentMD5 value on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that useTransactionalContentMD5 value.

Parameters:

useTransactionalContentMD5 - the useTransactionalContentMD5 to set

setStoreBlobContentMD5

public void setStoreBlobContentMD5(Boolean storeBlobContentMD5)

Sets whether the blob's ContentMD5 header should be set on uploads. This field is not supported for page blobs.

The default storeBlobContentMD5 value is set in the client and is by default true for block blobs. You can change the storeBlobContentMD5 value on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that storeBlobContentMD5 value.

Parameters:

storeBlobContentMD5 - the storeBlobContentMD5 to set

setDisableContentMD5Validation

public void setDisableContentMD5Validation(Boolean disableContentMD5Validation)

Sets whether download and BlobInputStream methods should ignore the blob's ContentMD5 header.

The default disableContentMD5Validation value is set in the client and is by default false. You can change the disableContentMD5Validation value on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that disableContentMD5Validation value.

Parameters:

disableContentMD5Validation - the disableContentMD5Validation to set

setSingleBlobPutThresholdInBytes

public void setSingleBlobPutThresholdInBytes(Integer singleBlobPutThresholdInBytes)

Sets the threshold size used for writing a single blob to use.

The default threshold size is set in the client and is by default 32MB. You can change the threshold size on this request by setting this property. You can also change the value on the CloudBlobClient.getDefaultRequestOptions() object so that all subsequent requests made via the service client will use that threshold size.

Parameters:

singleBlobPutThresholdInBytes - The maximum size, in bytes, of a blob that may be uploaded as a single blob, ranging from 1 MB to 64 MB inclusive. If a blob size is above the threshold, it will be uploaded as blocks.

Throws:

IllegalArgumentException - If minimumReadSize is less than 1 MB or greater than 64 MB.
