IMPORTANT: This documentation has been discontinued. Read the updated File Functions documentation on our new documentation portal.
The functions were created to:
speed up the creation of your integrations even more
decrease the complexity of your pipelines
simplify data conversions and transformations during the flow of your pipelines
The file functions make queries to metadata and make validations in files and are available for components that support Double Braces expressions. To know how to provide information to the components using this resource, click here.
FILEEXISTS
This function in Double Braces allows you to discover if a file exists in the virtual directory of the pipeline deployment.
Syntax
FILEEXISTS(file)
file: name of the file in the virtual directory of the pipeline
The function returns “true” when the file is found and “false” when it's not found.
FILESIZE
This function in Double Braces allows you to obtain the size of a file in the virtual directory of the pipeline deployment.
Syntax
FILESIZE(file)
file: name of the file in the virtual directory of the pipeline
Let's say you need to obtain the size of the file created one step before the use of the File Writer component. If its file name configuration in File Writer was "file.txt", then use the following extract in the JSON Generator component:
{
"fileSize": {{ FILESIZE("arquivo.txt") }}
}
The result would be:
{
"fileSize": 1000
}
fileSize: value representing the size of the file
