Constructor Detail

hs_expr_info_t

public hs_expr_info_t()

Default native constructor.

hs_expr_info_t

public hs_expr_info_t(long size)

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

hs_expr_info_t

public hs_expr_info_t(Pointer p)

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

Method Detail

position

public hs_expr_info_t position(long position)

Overrides:

position in class Pointer

min_width

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

The minimum length in bytes of a match for the pattern. Note: in some cases when using advanced features to suppress matches (such as extended parameters or the \ref HS_FLAG_SINGLEMATCH flag) this may represent a conservative lower bound for the true minimum length of a match.

min_width

public hs_expr_info_t min_width(int setter)

max_width

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

The maximum length in bytes of a match for the pattern. If the pattern has an unbounded maximum length, this will be set to the maximum value of an unsigned int (UINT_MAX). Note: in some cases when using advanced features to suppress matches (such as extended parameters or the \ref HS_FLAG_SINGLEMATCH flag) this may represent a conservative upper bound for the true maximum length of a match.

max_width

public hs_expr_info_t max_width(int setter)

unordered_matches

@Cast(value="char")
public byte unordered_matches()

Whether this expression can produce matches that are not returned in order, such as those produced by assertions. Zero if false, non-zero if true.

unordered_matches

public hs_expr_info_t unordered_matches(byte setter)

matches_at_eod

@Cast(value="char")
public byte matches_at_eod()

Whether this expression can produce matches at end of data (EOD). In streaming mode, EOD matches are raised during \ref hs_close_stream(), since it is only when \ref hs_close_stream() is called that the EOD location is known. Zero if false, non-zero if true. Note: trailing \b word boundary assertions may also result in EOD matches as end-of-data can act as a word boundary.

matches_at_eod

public hs_expr_info_t matches_at_eod(byte setter)

matches_only_at_eod

@Cast(value="char")
public byte matches_only_at_eod()

Whether this expression can *only* produce matches at end of data (EOD). In streaming mode, all matches for this expression are raised during \ref hs_close_stream(). Zero if false, non-zero if true.

matches_only_at_eod

public hs_expr_info_t matches_only_at_eod(byte setter)
