org.springframework.batch.item.support.AbstractItemCountingItemStreamItemReader<LdapAttributes>

org.springframework.ldap.ldif.batch.LdifReader

All Implemented Interfaces:

Deprecated.

Use the support provided in Spring Batch infrastructure

@Deprecated
public class LdifReader
extends org.springframework.batch.item.support.AbstractItemCountingItemStreamItemReader<LdapAttributes>
implements org.springframework.batch.item.file.ResourceAwareItemReaderItemStream<LdapAttributes>, InitializingBean

The LdifReader is an adaptation of the FlatFileItemReader built around an LdifParser.

Unlike the FlatFileItemReader, the LdifReader does not require a mapper. Instead, this version of the LdifReader simply returns an LdapAttributes object which can be consumed and manipulated as necessary by ItemProcessor or any output service. Alternatively, the RecordMapper interface can be implemented and set in a MappingLdifReader to map records to objects for return.

LdifReader usage is mimics that of the FlatFileItemReader for all intensive purposes. Adjustments have been made to process records instead of lines, however. As such, the recordsToSkip attribute indicates the number of records from the top of the file that should not be processed. Implementations of the RecordCallbackHandler interface can be used to execute operations on those skipped records.

As with the FlatFileItemReader, the strict option differentiates between whether or not to require the resource to exist before processing. In the case of a value set to false, a warning is logged instead of an exception being thrown.

Method Detail

setStrict

public void setStrict(boolean strict)

Deprecated.

In strict mode the reader will throw an exception on AbstractItemCountingItemStreamItemReader.open(org.springframework.batch.item.ExecutionContext) if the input resource does not exist.

Parameters:

strict - false by default

setSkippedRecordsCallback

public void setSkippedRecordsCallback(RecordCallbackHandler skippedRecordsCallback)

Deprecated.

RecordCallbackHandler implementations can be used to take action on skipped records.

Parameters:

skippedRecordsCallback - will be called for each one of the initial skipped lines before any items are read.

setRecordsToSkip

public void setRecordsToSkip(int recordsToSkip)

Deprecated.

Public setter for the number of lines to skip at the start of a file. Can be used if the file contains a header without useful (column name) information, and without a comment delimiter at the beginning of the lines.

Parameters:

recordsToSkip - the number of lines to skip
