public interface Output extends ByteOutput
Interface for a sink for binary output. This is similar to java.util.DataOutput, but no IOExceptions are declared, and multibyte output is defined to be little-endian.

  • Method Details

    • getCursor

      int getCursor()
      Gets the current cursor position. This is the same as the number of bytes written to this instance.
      Returns:
      >= 0; the cursor position

    • assertCursor

      void assertCursor(int expectedCursor)
      Asserts that the cursor is the given value.
      Parameters:
      expectedCursor - the expected cursor value
      Throws:
      RuntimeException - thrown if getCursor() != expectedCursor

    • writeByte

      void writeByte(int value)
      Writes a byte to this instance.
      Specified by:
      writeByte in interface ByteOutput
      Parameters:
      value - the value to write; all but the low 8 bits are ignored

    • writeShort

      void writeShort(int value)
      Writes a short to this instance.
      Parameters:
      value - the value to write; all but the low 16 bits are ignored

    • writeInt

      void writeInt(int value)
      Writes an int to this instance.
      Parameters:
      value - the value to write

    • writeLong

      void writeLong(long value)
      Writes a long to this instance.
      Parameters:
      value - the value to write

    • writeUleb128

      int writeUleb128(int value)
      Writes a DWARFv3-style unsigned LEB128 integer. For details, see the "Dalvik Executable Format" document or DWARF v3 section 7.6.
      Parameters:
      value - value to write, treated as an unsigned value
      Returns:
      1..5; the number of bytes actually written

    • writeSleb128

      int writeSleb128(int value)
      Writes a DWARFv3-style unsigned LEB128 integer. For details, see the "Dalvik Executable Format" document or DWARF v3 section 7.6.
      Parameters:
      value - value to write
      Returns:
      1..5; the number of bytes actually written

    • write

      void write(ByteArray bytes)
      Writes a ByteArray to this instance.
      Parameters:
      bytes - non-null; the array to write

    • write

      void write(byte[] bytes, int offset, int length)
      Writes a portion of a byte[] to this instance.
      Parameters:
      bytes - non-null; the array to write
      offset - >= 0; offset into bytes for the first byte to write
      length - >= 0; number of bytes to write

    • write

      void write(byte[] bytes)
      Writes a byte[] to this instance. This is just a convenient shorthand for write(bytes, 0, bytes.length).
      Parameters:
      bytes - non-null; the array to write

    • writeZeroes

      void writeZeroes(int count)
      Writes the given number of 0 bytes.
      Parameters:
      count - >= 0; the number of zeroes to write

    • alignTo

      void alignTo(int alignment)
      Adds extra bytes if necessary (with value 0) to force alignment of the output cursor as given.
      Parameters:
      alignment - > 0; the alignment; must be a power of two
