public class PasteFiles extends AbstractFileWriter
Generates a single file from combined lines from the input files. Line-by-line the lines get joined (separated by the specified delimiter) and output in the output file.
This transformer works similar to the Unix 'paste' command. But instead of providing a list of delimiters, a single one is used.
Input/output:
- accepts:
java.lang.String[]
java.io.File[]
Valid options are:
-D <int> (property: debugLevel) The greater the number the more additional info the scheme may output to the console (0 = off). default: 0 minimum: 0
-name <java.lang.String> (property: name) The name of the actor. default: PasteFiles
-annotation <adams.core.base.BaseText> (property: annotations) The annotations to attach to this actor. default:
-skip (property: skip) If set to true, transformation is skipped and the input token is just forwarded as it is.
-stop-flow-on-error (property: stopFlowOnError) If set to true, the flow gets stopped in case this actor encounters an error; useful for critical actors.
-output <adams.core.io.PlaceholderFile> (property: outputFile) The output file containing the combined content. default: ${CWD}
-delimiter <java.lang.String> (property: delimiter) The delimiter to use for combining the lines (backquoted, e.g., use ' ' for tab). default: \\t
