getAppsScriptBlob()
getAs(contentType)
Return the data inside this object as a blob converted to the specified content type. This method adds the appropriate extension to the filename—for example, "myfile.pdf". However, it assumes that the part of the filename that follows the last period (if any) is an existing extension that should be replaced. Consequently, "ShoppingList.12.25.2014" becomes "ShoppingList.12.25.pdf".
To view the daily quotas for conversions, see Quotas for Google Services. Newly created Google Workspace domains might be temporarily subject to stricter quotas.
Parameters
Name | Type | Description |
---|---|---|
contentType | String | The MIME type to convert to. For most blobs, 'application/pdf' is
the only valid option. For images in BMP, GIF, JPEG, or PNG format, any of 'image/bmp' , 'image/gif' , 'image/jpeg' , or 'image/png' are also
valid. For a Google Docs document, 'text/markdown' is also valid. |
Return
Blob
— The data as a blob.
getBytes(position, length)
For documentation of this method, see
java.sql.Blob#getBytes(long, int)
.
Parameters
Name | Type | Description |
---|---|---|
position | Integer | The ordinal position of the first byte in the blob value to be extracted; the first byte is at position 1. |
length | Integer | The number of consecutive bytes to copy; the value for length must be zero or greater. |
Return
Byte[]
— A byte array containing up to the specified number of consecutive bytes from the blob
value.
length()
For documentation of this method, see
java.sql.Blob#length()
.
Return
Integer
— The number of bytes in this blob.
position(pattern, start)
For documentation of this method, see
java.sql.Blob#position(byte[], long)
.
Parameters
Name | Type | Description |
---|---|---|
pattern | Byte[] | The byte array to search for. |
start | Integer | The position in the blob value where to beging searching; the first position is 1. |
Return
Integer
— The position at which the specified pattern begins, or else -1 if the pattern is not
found.
position(pattern, start)
For documentation of this method, see
java.sql.Blob#position(blob, long)
.
Parameters
Name | Type | Description |
---|---|---|
pattern | JdbcBlob | The JdbcBlob indicating the value to search for. |
start | Integer | The position in the blob value where to beging searching; the first position is 1. |
Return
Integer
— The position at which the specified pattern begins, or else -1 if the pattern is not
found.
