Member Function Documentation

void com.sparsity.sparksee.io.NodeTypeLoader.Register

(

com.sparsity.sparksee.io.TypeLoaderListener

tel

)

Registers a new listener.

Parameters

tel	TypeLoaderListener to be registered.

void com.sparsity.sparksee.io.NodeTypeLoader.Run

(

)

throws System.IO.IOException, System.ApplicationException

See the TypeLoader class Run method.

Exceptions

System.IO.IOException	null
System.ApplicationException	null

void com.sparsity.sparksee.io.NodeTypeLoader.RunNPhases

(

int

partitions

)

throws System.IO.IOException, System.ApplicationException

See the TypeLoader class RunNPhases method.

Parameters

partitions

null

Exceptions

System.IO.IOException	null
System.ApplicationException	null

void com.sparsity.sparksee.io.NodeTypeLoader.RunTwoPhases

(

)

throws System.IO.IOException, System.ApplicationException

See the TypeLoader class RunTwoPhases method.

Exceptions

System.IO.IOException	null
System.ApplicationException	null

void com.sparsity.sparksee.io.NodeTypeLoader.SetAttributePositions

(

com.sparsity.sparksee.gdb.Int32List

attrsPos

)

Sets the list of attribute positions.

Parameters

attrsPos

[in] Attribute positions (column index >=0).

void com.sparsity.sparksee.io.NodeTypeLoader.SetAttributes

(

com.sparsity.sparksee.gdb.AttributeList

attrs

)

Sets the list of Attributes.

Parameters

attrs

[in] Attribute identifiers to be loaded

void com.sparsity.sparksee.io.NodeTypeLoader.SetFrequency

(

int

freq

)

Sets the frequency of listener notification.

Parameters

freq	[in] Frequency in number of rows managed to notify progress to all listeners

void com.sparsity.sparksee.io.NodeTypeLoader.SetGraph

(

com.sparsity.sparksee.gdb.Graph

graph

)

Sets the graph where the data will be loaded.

Parameters

graph

[in] Graph.

void com.sparsity.sparksee.io.NodeTypeLoader.SetLocale

(

System.String

localeStr

)

Sets the locale that will be used to read the data.

It should match the locale used in the rowreader.

Parameters

localeStr

[in] The locale string for the read data. See CSVReader.

void com.sparsity.sparksee.io.NodeTypeLoader.SetLogError

(

System.String

path

)

throws System.IO.IOException

Sets a log error file.

By default errors are thrown as a exception and the load process ends. If a log file is set, errors are logged there and the load process does not stop.

Parameters

path	[in] The path to the error log file.

Exceptions

System.IO.IOException

If bad things happen opening the file.

void com.sparsity.sparksee.io.NodeTypeLoader.SetLogOff

(

)

Truns off all the error reporting.

The log file will not be created and no exceptions for invalid data will be thrown. If you just want to turn off the logs, but abort at the first error what you should do is not call this method and not set a logError file.

void com.sparsity.sparksee.io.NodeTypeLoader.SetRowReader

(

com.sparsity.sparksee.io.RowReader

rr

)

Sets the input data source.

Parameters

rr	[in] Input RowReader.

void com.sparsity.sparksee.io.NodeTypeLoader.SetTimestampFormat

(

System.String

timestampFormat

)

Sets a specific timestamp format.

Parameters

timestampFormat

[in] A string with the timestamp format definition.

void com.sparsity.sparksee.io.NodeTypeLoader.SetType

(

int

type

)

Sets the type to be loaded.

Parameters

type	[in] Type identifier.
