org.bytedeco.hyperscan.hs_expr_ext_t

All Implemented Interfaces:

AutoCloseable

@Properties(inherit=hyperscan.class)
public class hs_expr_ext_t
extends Pointer

A structure containing additional parameters related to an expression, passed in at build time to \ref hs_compile_ext_multi() or \ref hs_expression_ext_info. These parameters allow the set of matches produced by a pattern to be constrained at compile time, rather than relying on the application to process unwanted matches at runtime.

Constructor Detail

hs_expr_ext_t

public hs_expr_ext_t()

Default native constructor.

hs_expr_ext_t

public hs_expr_ext_t(long size)

Native array allocator. Access with Pointer.position(long).

hs_expr_ext_t

public hs_expr_ext_t(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public hs_expr_ext_t position(long position)

Overrides:

position in class Pointer

flags

@Cast(value="unsigned long long")
public long flags()

Flags governing which parts of this structure are to be used by the compiler. See \ref HS_EXT_FLAG.

flags

public hs_expr_ext_t flags(long setter)

min_offset

@Cast(value="unsigned long long")
public long min_offset()

The minimum end offset in the data stream at which this expression should match successfully. To use this parameter, set the \ref HS_EXT_FLAG_MIN_OFFSET flag in the hs_expr_ext::flags field.

min_offset

public hs_expr_ext_t min_offset(long setter)

max_offset

@Cast(value="unsigned long long")
public long max_offset()

The maximum end offset in the data stream at which this expression should match successfully. To use this parameter, set the \ref HS_EXT_FLAG_MAX_OFFSET flag in the hs_expr_ext::flags field.

max_offset

public hs_expr_ext_t max_offset(long setter)

min_length

@Cast(value="unsigned long long")
public long min_length()

The minimum match length (from start to end) required to successfully match this expression. To use this parameter, set the \ref HS_EXT_FLAG_MIN_LENGTH flag in the hs_expr_ext::flags field.

min_length

public hs_expr_ext_t min_length(long setter)

edit_distance

@Cast(value="unsigned")
public int edit_distance()

Allow patterns to approximately match within this edit distance. To use this parameter, set the \ref HS_EXT_FLAG_EDIT_DISTANCE flag in the hs_expr_ext::flags field.

edit_distance

public hs_expr_ext_t edit_distance(int setter)

hamming_distance

@Cast(value="unsigned")
public int hamming_distance()

Allow patterns to approximately match within this Hamming distance. To use this parameter, set the \ref HS_EXT_FLAG_HAMMING_DISTANCE flag in the hs_expr_ext::flags field.

hamming_distance

public hs_expr_ext_t hamming_distance(int setter)
