方法详细资料

getInputFields

public F[] getInputFields()

返回:

the input fields.

clone

public Object clone()

从接口复制的说明: StepMetaInterface

Make an exact copy of this step, make sure to explicitly copy Collections etc.

指定者:

clone 在接口中 StepMetaInterface

覆盖:

clone 在类中 BaseStepMeta

返回:

an exact copy of this step

inputFiles_fileRequired

public void inputFiles_fileRequired(String[] fileRequiredin)

参数:

fileRequiredin - The fileRequired to set.

inputFiles_includeSubFolders

public String[] inputFiles_includeSubFolders()

inputFiles_includeSubFolders

public void inputFiles_includeSubFolders(String[] includeSubFoldersin)

getRequiredFilesCode

public static String getRequiredFilesCode(String tt)

getFileInputList

public org.pentaho.di.core.fileinput.FileInputList getFileInputList(org.pentaho.di.core.variables.VariableSpace space)

getResourceDependencies

public List<ResourceReference> getResourceDependencies(TransMeta transMeta,
                                                       StepMeta stepInfo)

从类复制的说明: BaseStepMeta

Get a list of all the resource dependencies that the step is depending on.

指定者:

getResourceDependencies 在接口中 StepMetaInterface

覆盖:

getResourceDependencies 在类中 BaseStepMeta

返回:

a list of all the resource dependencies that the step is depending on

getEncoding

public abstract String getEncoding()

isAcceptingFilenames

public boolean isAcceptingFilenames()

getAcceptingStepName

public String getAcceptingStepName()

getAcceptingField

public String getAcceptingField()

getFilePaths

public String[] getFilePaths(boolean showSamples)

指定者:

getFilePaths 在类中 BaseFileMeta

参数:

showSamples - determines whether the paths being returned are dummy samples or the "template" representation. The samples woulc include things like sample step number, partition number etc ( filename_0_1.txt) , while the non-sample path would include a token ( filename_<step>_<partition>.<extension>)

返回:

An array of file paths
