      Description copied from interface: BasedOptionsHolder
      Options test for options for this sequence

      default reports true for global default options (if any) , variation available on BasedSequenceWithOptions

      Returns:

      default reports true for global default options (if any) , variation available on BasedSequenceWithOptions

      Parameters:
      options - option flags
      Returns:
      true if all option flags passed are set for this sequence

    • anyOptions

      public boolean anyOptions(int options)
      Description copied from interface: BasedOptionsHolder
      Options test for options for this sequence

      default reports true for global default options (if any) , variation available on BasedSequenceWithOptions

      Parameters:
      options - option flags
      Returns:
      true if any option flags passed are set for this sequence

    • getOption

      public <T> T getOption(DataKeyBase<T> dataKey)
      Description copied from interface: BasedOptionsHolder
      Options holder, default has none, only available on BasedSequenceWithOptions
      Type Parameters:
      T - type of value held by key
      Parameters:
      dataKey - in options
      Returns:
      true if data key is available

    • getOptions

      @Nullable public @Nullable DataHolder getOptions()
      Description copied from interface: BasedOptionsHolder
      Options holder, default has none, only available on BasedSequenceWithOptions
      Returns:
      data holder with options or null if none for this sequence

    • length

      public int length()

    • charAt

      public char charAt(int index)

    • getIndexOffset

      public int getIndexOffset(int index)
      Description copied from interface: BasedSequence
      Get the offset of index in this sequence mapped to offset into BasedSequence.getBaseSequence() and BasedSequence.getBase() original text source. NOTE: if the character at given index does not equal the corresponding character in the base sequence then this method should return -1 otherwise segmented based sequence will be created for original base character
      Parameters:
      index - index for which to get the offset in original source
      Returns:
      offset of index of this sequence in original text

    • subSequence

      @NotNull public @NotNull BasedSequence subSequence(int i, int i1)
      Description copied from interface: IRichSequence
      Get a portion of this sequence

      NOTE: the returned value should only depend on start/end indices. If a subsequence of this sequence with matching start/end should equal (using equals()) all such subsequences of this sequence.

      Parameters:
      i - offset from startIndex of this sequence
      i1 - offset from startIndex of this sequence
      Returns:
      based sequence whose contents reflect the selected portion

    • baseSubSequence

      @NotNull public @NotNull BasedSequence baseSubSequence(int startIndex, int endIndex)
      Description copied from interface: BasedSequence
      Get a portion of this sequence's base sequence

      NOTE: this means that if this sequence applies modifications to the original sequence then these modifications are NOT be applied to the returned sequence.

      NOTE: It should only be implemented in classes which provide base sequences such as CharSubSequence and SubSequence others use inherited implementation of BasedSequenceImpl

      Specified by:
      baseSubSequence in interface BasedSequence
      Overrides:
      baseSubSequence in class BasedSequenceImpl
      Parameters:
      startIndex - offset from 0 of original sequence
      endIndex - offset from 0 of original sequence
      Returns:
      based sequence whose contents reflect the selected portion

    • getBaseSequence

      @NotNull public @NotNull BasedSequence getBaseSequence()
      Description copied from interface: BasedSequence
      Get the base sequence for the text
      Returns:
      base sequence

    • getBase

      @NotNull public @NotNull BasedSequence getBase()
      Description copied from interface: BasedSequence
      Get the underlying object on which this sequence contents are based
      Returns:
      underlying object containing original text

    • getStartOffset

      public int getStartOffset()
      Description copied from interface: BasedSequence
      Get the start offset of this sequence into BasedSequence.getBaseSequence() and BasedSequence.getBase() original text source.
      Returns:
      start offset in original text

    • getEndOffset

      public int getEndOffset()
      Description copied from interface: BasedSequence
      Get the end offset of this sequence into BasedSequence.getBaseSequence() and BasedSequence.getBase() original text source.
      Returns:
      end offset in original text

    • getSourceRange

      @NotNull public @NotNull Range getSourceRange()
      Description copied from interface: BasedSequence
      Get the range of this sequence in original BasedSequence.getBaseSequence() and BasedSequence.getBase() original text source.
