public class RdwCobolComplexTypeFinder
extends CobolComplexTypeFinder

When complex types are preceded by a Record Descriptor Word (RDW), the RDW itself can be used as part of the matching pattern.

RdwCobolComplexTypeFinder

public RdwCobolComplexTypeFinder(CobolContext cobolContext,
                                 CobolComplexType cobolComplexType,
                                 String stopFieldInclusive)

Method Detail

match

public boolean match(byte[] hostData,
                     int start,
                     int length)

Description copied from class: CobolComplexTypeFinder

Match a Cobol type to an incoming host bytes set.

Overrides:

match in class CobolComplexTypeFinder

Parameters:

hostData - the host bytes set

start - where to start matching

length - the size of the incoming host bytes set. This should be large enough to hold a signature but is not guaranteed to hold more than that.

Returns:

true if the Cobol type is compatible with the host bytes at the given start position

getRdw

public int getRdw(byte[] hostData,
                  int start,
                  int length)

getSignatureLen

public int getSignatureLen()

Description copied from class: CobolComplexTypeFinder

Overrides:

getSignatureLen in class CobolComplexTypeFinder

Returns:

the byte length of the signature (total number of bytes needed to match the type)
