public class CallScriptCmd
extends CustomizableCommand

A call script command takes a list of input relation and produces an output relation. Each input relation corresponds to a list of attributes. An attribute carries an expression and a name. The output is composed of a list of attributes, each having a name.

There are APIs to customize the following information that define a call script command:

• A list of list of input expressions.
• A list of list of input attribute names.
• A list of target attribute names.
• The content of the script being called.

Since:

12.1.4

Method Detail

getTypeEnum

public CommandType getTypeEnum()

Description copied from class: Command

Gets the enumeration command type.

Specified by:

getTypeEnum in class Command

Returns:

the enum command type.

isSelector

public boolean isSelector()

Description copied from class: Command

Gets if this command is a selector. A selector command will have all its input fields cloned into its output schema.

Specified by:

isSelector in class Command

Returns:

true if this is a selector, false otherwise.

isDecorator

public boolean isDecorator()

Description copied from class: Command

Gets if this command is a decorator. A decorator command will have output fields that are not clones from any input schemas.

Specified by:

isDecorator in class Command

Returns:

true if this is a decorator, false otherwise.

getInputExprsList

public java.util.List getInputExprsList()

Gets the lists of input expressions, one list for each input connector point.

Returns:

lists of input expressions.

setInputExprsList

public void setInputExprsList(java.util.List inputExprsList)

Sets lists of input expressions.

Parameters:

inputExprsList - lists of input expressions to be set.

getInputAttrNamesList

public java.util.List getInputAttrNamesList()

Gets lists of attribute names. One list for each input connector point.

Returns:

lists of attribute names.

setInputAttrNamesListp

public void setInputAttrNamesListp(java.util.List inputAttrNamesList)

Sets input attribute names.

Parameters:

inputAttrNamesList - lists of input attribute names, one for each input connector point.

getTgtAttrNames

public java.util.List getTgtAttrNames()

Gets names for target attributes

Returns:

names of target attr names.

setTgtAttrNames

public void setTgtAttrNames(java.util.List tgtAttrNames)

Sets names for target attributes.

Parameters:

tgtAttrNames - target attribute names to be set.

getScriptContent

public java.lang.String getScriptContent()

Gets the content for the script to be called. Note: Originally, the design is the allow user to only specifiy a script name, and this command just runs the script. However, due to some complication in the runtime, this is not doable. The solution is to ask user to paste the content of the script to be called here.

Returns:

the content of the script to be run.

setScriptContent

public void setScriptContent(java.lang.String pigScriptContent)

Sets the content for the script.

Parameters:

pigScriptContent - the content of the script to be called by this command.
