getSpecificationMethod

public ObjectLocationSpecificationMethod getSpecificationMethod()

Returns:

getSpecificationMethods

public ObjectLocationSpecificationMethod[] getSpecificationMethods()

Description copied from interface: HasRepositoryDirectories

If step has reference(s) to another transformation(s)/job(s) returns an array of specification method(s) defining the type of an access to a referenced file. An implementation is considered to define the array order itself.

Specified by:

getSpecificationMethods in interface HasRepositoryDirectories

Returns:

String array of specification method(s)

setSpecificationMethod

public void setSpecificationMethod(ObjectLocationSpecificationMethod specificationMethod)

Parameters:

specificationMethod - the specificationMethod to set

Returns:

the directoryPath

setDirectoryPath

public void setDirectoryPath(String directoryPath)

Parameters:

directoryPath - the directoryPath to set

getDirectories

public String[] getDirectories()

Description copied from interface: HasRepositoryDirectories

If step has reference(s) to another transformation(s)/job(s) returns an array of repository directories. An implementation is considered to define the array order itself.

Specified by:

getDirectories in interface HasRepositoryDirectories

Returns:

String array of repository directories

setDirectories

public void setDirectories(String[] directories)

Description copied from interface: HasRepositoryDirectories

If step has reference(s) to another transformation(s)/job(s) sets updated repository directories from incoming String array. An implementation is considered to define the array order itself.

Specified by:
