Constructor Detail

FileEnhMethodHandler

public FileEnhMethodHandler()

Default Constructor.

FileEnhMethodHandler

public FileEnhMethodHandler(java.util.Hashtable lt,
                            java.lang.String subValueSeparator)

Constructor for the FileEnhMethodHandler. Sets up an NPLFieldProcessor and sets the DCFieldContainer to be a NAR. At the end of the constructor the node is started.

Parameters:

lt - the lookup table that will be used for lookup call
It is expected this will be a Hashtable of Hashtables.

Method Detail

setLookupTable

public void setLookupTable(java.util.Hashtable lt)

Method for setting the lookup table that will be used by the NPL program.

Parameters:

lt - the lookup table that will be used for lookup call
It is expected this will be a Hashtable of Hashtables.

setLookupTable

public void setLookupTable(java.lang.String key,
                           java.util.Hashtable lt)

Specified by:

setLookupTable in interface LookupIfc

getLookupTable

public java.util.Hashtable getLookupTable()

Gets the entire lookup table that is being used in the NPL java-hook lookup call. This table should be a Hashtable of Hashtables

Returns:

Returns the Hashtable representing the lookup table.

getLookupTable

public java.util.Hashtable getLookupTable(java.lang.String key)

Specified by:

getLookupTable in interface LookupIfc

lookup

public StringField lookup(StringField tableName,
                          StringField key)

Method intended to be call from NPL as a "java-hook". This is specifically used for the purpose of table lookup. The structure of the object from which this lookup is being done is a Hashtable of Hashtables. Therefore, the call is made with a "tableName" parameter to select the sub-table to use, and then a "key" parameter to extract a specific field from that sub-table. Parameters and return values are all StringField, as NPL only allows java-hooks with DCField sub-classes.

Specified by:

lookup in interface FileEnhMethodHandlerIfc

Parameters:

tableName - the specific sub-table to look in

key - the specific element in the sub-table

Returns:

Returns the StringField representing the element value.

getSubValue

public StringField getSubValue(StringField lookup,
                               StringField key)

Specified by:

getSubValue in interface FileEnhMethodHandlerIfc
