Interface Summary

IncrementalProcessor

An IncrementalProcessor is used by the IncrementalProcessorInputStream to perform processing that generates output in incremental stages.

Class Summary

BlockAggregatorActivity	This activity aggregates blocks together using overloaded processBlocks(Type) methods.
ByteQueue	A ByteQueue enqueues and dequeues bytes.
BytesToTempFileActivity	This activity takes an stream of byte arrays and writes them to a temporary file on the server.
ChecksumConverter	A helper class to convert Checksum objects into String representations.
CSVProjectionActivity	A CSVProjectionActivity projects the i-th value from a sequence of CSV values.
FrequencyDistributorActivity	A FrequencyDistributorActivity distributes the input values, that should be numeric, into the corresponding spaces that emerge from the parameter sequence of values.
GZIPCompressionActivity	An Activity to perform GZIP compression.
GZIPDecompressionActivity	An Activity to perform GZIP decompression.
GZIPIncrementalProcessor	An IncrementalProcessor that reads from an InputStream, compresses the data using GZIP compression, and writes to an OutputStream.
IncrementalProcessorInputStream	An InputStream designed to read the output of some kind of process in incremental stages.
RandomSampleActivity	A RandomSampleActivity takes as input a sequence of values and returns a random subset of them basen on the fraction provided.
StringTokenizerActivity	This activity tokenizes the input data it recieves using a specified set of delimiters.
WebRowSetProjectionActivity	A WebRowSetProjectionActivity projects a WebRowSet input document onto a column name or a column index.
XSLTransformActivity	An Activity to perform XSL-Transforms.
ZIPArchiveActivity	An Activity to archive and compress one or more inputs using the ZIP format.
ZIPIncrementalProcessor	An IncrementalProcessor to produce ZIP archives.

Exception Summary

BlockAggregatorSizeException	The blockAggregator activity was given a size attribute with an incorrect value.
IllegalDelimiterException	An illegal delimiter was provided.
MissingXSLTException	The xslTransform activity was not given an XSLT transform either inline or via an activity input.
ZIPArchiveCommentLengthException	The zipArchive activity was given a comment with an incorrect length.
