Method Detail

getTgtAttrExprs

public java.util.List getTgtAttrExprs()

Gets the list of expressions on target attributes.

Returns:

the list of target expressions.

setTgtAttrExprs

public void setTgtAttrExprs(java.util.List tgtAttrExprs)

Sets the list of target expressions.

Parameters:

targetAttrExprs - the list of target expressions to be set.

public java.util.List getTgtAttrNames()

Gets the names of target attributes.

Returns:

the names of target attributes.

setTgtAttrNames

public void setTgtAttrNames(java.util.List tgtAttrNames)

Sets the names of target attributes.

Parameters:

targetAttrNames - the names of target attributes to be set.
