Class GenericByteSequencePattern<T>

java.lang.Object

ghidra.util.bytesearch.DittedBitSequence

ghidra.util.bytesearch.Pattern

ghidra.util.bytesearch.GenericByteSequencePattern<T>

Type Parameters:

T - the class of match action, used to specify a specialized momento to be used by the action when it is "applied".

public class GenericByteSequencePattern<T>
extends Pattern

Templated simple DittedBitSequence Pattern for a byte/mask pattern and associated action. The DittedBitSequence is provided by value and mask in byte arrays. This class is normally used to find some number of SequencePatterns within a seqence of bytes. When the byte/mask pattern is matched, the GenericMatchAction will be "applied".

Constructor Details

GenericByteSequencePattern

public GenericByteSequencePattern(byte[] bytesSequence,
 GenericMatchAction<T> action)

Construct a sequence of bytes with no mask, and associated action to be called if this pattern matches.

Parameters:

bytesSequence - sequence of bytes to match

action - action to apply if the match succeeds

GenericByteSequencePattern

public GenericByteSequencePattern(byte[] bytesSequence,
 byte[] mask,
 GenericMatchAction<T> action)

Construct a sequence of bytes with a mask, and associated action to be called if this pattern matches.

Parameters:

bytesSequence - sequence of bytes to match

mask - mask, bits that are 1 must match the byteSequence bits

action - to apply if the match succeeds
