Field Detail

compressionLevel

public int compressionLevel

the compression level (number of nested compressions) that for the last compressed sequence.

compressed

public CompressedSequence compressed

the compressed sequence, after compression is performed

Constructor Detail

Compression

public Compression(Object[] nodes)

Create a new compression object that will compress the sequence nodes.

Parameters:

nodes - The sequence to compress.

Method Detail

fullyCompress

public void fullyCompress()

Fully compress a sequcence.

Parameters:

nodes - The sequence to compress.

compressedCode

public String compressedCode(String varPrefix)

Given a compressed sequence that is composed of objects with an appropriate toString() method defined, generate code (nested C for loops in an outer block) to execute the compressed schedule. At first, generate C code for the variable declarations. Make sure that you do not compress another sequence using this Compression object, because we use the value of compressionlevel for the var declarations.

Parameters:

seq -

varPrefix - The prefix to use for loop indices (these have been declared previously).

Returns:

compressedSequence

public String compressedSequence(CompressedSequence seq,
                                 int level,
                                 String varPrefix)

Parameters:

seq -

level -

varPrefix -

Returns:

toString

public String toString()

Overrides:

toString in class Object
