Reference: Document Accessor Helper Object

Name	Arguments	Return Value Type	Notes
getData	Integer index	Source	Retrieves the document at the specified zero-based index. Use in combination with the message.setMessage helper function to populate the current message with the retrieved data in a memory-efficient manner. Example: this code populates the current message with a UTF-8 XML message retrieved from the first attachment: message.setMessage(da.getData(0), ‘text/xml’) Results in an error if there's no integration attachment with the specified index.
	String filename	Source	Retrieves the document with the specified filename. Use in combination with the message.setMessage helper function to populate the current message with the retrieved data in a memory-efficient manner. Example: this code populates the current message with a UTF-8 XML message attachment with the name input.xml: message.setMessage(da.getData(‘input.xml’), ‘text/xml’) Results in an error if there's no integration attachment with the specified filename.
getDocumentIndexes	List<String> labels	List<Integer>	Returns a Java List of integers giving the indexes of documents tagged with all of the specified labels. Note that if one of the labels is ‘*’ then any label is matched and the function returns all indexes for documents with at least 1 label.
getDocsMatching	List<String>	List<Source>	Retrieves documents tagged with all of the specified labels. Workday stores documents smaller than 100 KB in memory and larger documents on disk. Be aware of runtime memory and disk space limits.
	String label	Source	Retrieves documents tagged with the specified label. Label here means integration attachment label. Synonymous with document tag.
	String[] labels	Source	Retrieves documents tagged with all of the labels in the string array.
getFileName	Integer index	String	Retrieves the filename with the specified index.
	String label	List<String>	Retrieves a Java List of the filenames of all the documents tagged with the specified label.
	List<String> labels	List<String>	Retrieves a Java List of the filenames of all the documents tagged with the specified labels.
	String label, integer index	String	Retrieves the nth filename of all the documents tagged with the specified label. Functionally equivalent to this code: da.getFileNames(label).get(index) In most cases, you must use da.getFileNames(label) to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.
	List<String> labels, integer index	String	Retrieves the nth filename of all the documents tagged with the specified labels. Functionally equivalent to this code: da.getFileNames(labels).get(index) In most cases, you must use da.getFileNames(labels) to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.
	String[] labels, integer index		Retrieves the nth filename of all the documents tagged with the specified labels. Functionally equivalent to this code: da.getFileNames(java.util.Arrays.asList(labels)).get(index) In most cases, you must use da.getFileNames(labels) to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.
hasFile	String filename	Boolean	Determines whether there's an integration attachment with the specified filename.
	String label, String filename	Boolean	Determines whether there's an integration attachment with the specified filename and tagged with the specified label.
	List<String> labels, String filename	Boolean	Determines whether there's an integration attachment with the specified filename and tagged with all of the labels in the list.
sort	String order	None	Sorts the attached documents by filename. Valid order values are: "FILENAME_ASCENDING" "FILENAME_DESCENDING" Any attachments with no filename place last.
size	None	Integer	Returns the number of attached documents.
	List<String> labels	Integer	Returns the number of documents tagged with all of the specified labels.
	String label	Integer	Returns the number of documents tagged with the specified label.
	String[] labels	Integer	Returns the number of documents tagged with all of the labels in the string array.
toVar	Integer index, String var_name	MessageVariable	Retrieves the document at the specified index and places it in a memory-efficient manner into the specified assembly variable. Example: da.toVar(0, ‘myInputDocument’)
	String filename, String var_name	MessageVariable	Retrieves the document with the specified filename and places it in a memory-efficient manner into the specified assembly variable. Example: da.toVar(‘WorkerData.xml’, ‘myInputDocument’)

getData

Integer index

Source

Retrieves the document at the specified zero-based index. Use in combination with the

message.setMessage

helper function to populate the current message with the retrieved data in a memory-efficient manner.

Example: this code populates the current message with a UTF-8 XML message retrieved from the first attachment:

message.setMessage(da.getData(0), ‘text/xml’)

Results in an error if there's no integration attachment with the specified index.

String filename

Source

Retrieves the document with the specified filename. Use in combination with the

message.setMessage

helper function to populate the current message with the retrieved data in a memory-efficient manner.

Example: this code populates the current message with a UTF-8 XML message attachment with the name input.xml:

message.setMessage(da.getData(‘input.xml’), ‘text/xml’)

Results in an error if there's no integration attachment with the specified filename.

getDocumentIndexes

List<String> labels

List<Integer>

Returns a Java List of integers giving the indexes of documents tagged with all of the specified labels.

Note that if one of the labels is ‘*’ then any label is matched and the function returns all indexes for documents with at least 1 label.

getDocsMatching

List<String>

List<Source>

Retrieves documents tagged with all of the specified labels.

Workday stores documents smaller than 100 KB in memory and larger documents on disk. Be aware of runtime memory and disk space limits.

String label

Source

Retrieves documents tagged with the specified label.

Label here means integration attachment label. Synonymous with document tag.

String[] labels

Source

Retrieves documents tagged with all of the labels in the string array.

getFileName

Integer index

String

Retrieves the filename with the specified index.

String label

List<String>

Retrieves a Java List of the filenames of all the documents tagged with the specified label.

List<String> labels

List<String>

Retrieves a Java List of the filenames of all the documents tagged with the specified labels.

String label, integer index

String

Retrieves the nth filename of all the documents tagged with the specified label.

Functionally equivalent to this code:

da.getFileNames(label).get(index)

In most cases, you must use

da.getFileNames(label)

to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.

List<String> labels, integer index

String

Retrieves the nth filename of all the documents tagged with the specified labels.

Functionally equivalent to this code:

da.getFileNames(labels).get(index)

In most cases, you must use

da.getFileNames(labels)

to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.

String[] labels, integer index

Retrieves the nth filename of all the documents tagged with the specified labels.

Functionally equivalent to this code:

da.getFileNames(java.util.Arrays.asList(labels)).get(index)

In most cases, you must use

da.getFileNames(labels)

to find the number of matching filenames before you can use an index. The only exception is the limited case where you require the first (zero index) value.

hasFile
