Class Skipper

Object
com.owenfeehan.pathpatternfinder.patternelements.unresolved.Skipper
public class Skipper
extends Object
Skips certain kind of resolves operations if it is known a priori that they are unneeded.

If we already know certain operations will fail, as they've been tried before, then they can be deliberately skipped to save computation. This class specifies flags for these operations that can be skipped.

      public Skipper()
      Creates with default values (include everything, and #getStartSplitCharIndex() of 0).

      public Skipper​(boolean includeLeftResolve, boolean includeRightResolve, int startSplitCharIndex)
      Creates with explicit values for flags.
      Parameters:
      includeLeftResolve - whether to try to resolve from the left. We can disable this operation, if we've already tried without success, and don't wish to repeat needlessly.
      includeRightResolve - whether to try to resolve from the right. We can disable this operation, if we've already tried without success, and don't wish to repeat needlessly.
      startSplitCharIndex - the minimum index from which we start attempting to split characters, to avoid repeating

  • Method Details

    • includeLeftResolve

      public boolean includeLeftResolve()
      Whether to try to resolve from the left. We can disable this operation, if we've already tried without success, and don't wish to repeat needlessly.
      Returns:
      true if resolution should be tried, false if it should not be.

    • includeRightResolve

      public boolean includeRightResolve()
      Whether to try to resolve from the right. We can disable this operation, if we've already tried without success, and don't wish to repeat needlessly.
      Returns:
      true if resolution should be tried, false if it should not be.

    • getStartSplitCharIndex

      public int getStartSplitCharIndex()
      The minimum index from which we start attempting to split characters, to avoid repeating.
      Returns:
      the index

    • swapResolves

      public void swapResolves()
      Switch whether to resolve from the left, with whether to resolve from the right.
