public class ArrayType extends AbstractType

  • Constructor Details

    • ArrayType

      public ArrayType(Type elementType)

  • Method Details

    • getTypeOperatorDeclaration

      public TypeOperatorDeclaration getTypeOperatorDeclaration(TypeOperators typeOperators)
      Description copied from interface: Type
      Gets the declared type specific operators for this type.

    • getElementType

      public Type getElementType()

    • isComparable

      public boolean isComparable()
      Description copied from interface: Type
      True if the type supports equalTo and hash.
      Specified by:
      isComparable in interface Type
      Overrides:
      isComparable in class AbstractType

    • isOrderable

      public boolean isOrderable()
      Description copied from interface: Type
      True if the type supports compareTo.
      Specified by:
      isOrderable in interface Type
      Overrides:
      isOrderable in class AbstractType

    • getObjectValue

      public Object getObjectValue(ConnectorSession session, Block block, int position)
      Description copied from interface: Type
      Gets an object representation of the type value in the block position. This is the value returned to the user via the REST endpoint and therefore must be JSON serializable.

    • appendTo

      public void appendTo(Block block, int position, BlockBuilder blockBuilder)
      Description copied from interface: Type
      Append the value at position in block to blockBuilder.

    • getObject

      public Block getObject(Block block, int position)
      Description copied from interface: Type
      Gets the value at the block position as an Object.
      Specified by:
      getObject in interface Type
      Overrides:
      getObject in class AbstractType

    • writeObject

      public void writeObject(BlockBuilder blockBuilder, Object value)
      Description copied from interface: Type
      Writes the Object value into the BlockBuilder.
      Specified by:
      writeObject in interface Type
      Overrides:
      writeObject in class AbstractType

    • getFlatFixedSize

      public int getFlatFixedSize()
      Description copied from interface: Type
      Returns the fixed size of this type when written to a flat buffer.

    • isFlatVariableWidth

      public boolean isFlatVariableWidth()
      Description copied from interface: Type
      Returns true if this type is variable width when written to a flat buffer.

    • getFlatVariableWidthSize

      public int getFlatVariableWidthSize(Block block, int position)
      Description copied from interface: Type
      Returns the variable width size of the value at the specified position when written to a flat buffer.

    • relocateFlatVariableWidthOffsets

      public int relocateFlatVariableWidthOffsets(byte[] fixedSizeSlice, int fixedSizeOffset, byte[] variableSizeSlice, int variableSizeOffset)
      Description copied from interface: Type
      Update the variable width offsets recorded in the value. This method is called after the value has been moved to a new location, and therefore the offsets need to be updated. Returns the length of the variable width data, so container types can update their offsets.
      Returns:
      the length of the variable width data

    • createBlockBuilder

      public ArrayBlockBuilder createBlockBuilder(BlockBuilderStatus blockBuilderStatus, int expectedEntries, int expectedBytesPerEntry)
      Description copied from interface: Type
      Creates the preferred block builder for this type. This is the builder used to store values after an expression projection within the query.

    • createBlockBuilder

      public ArrayBlockBuilder createBlockBuilder(BlockBuilderStatus blockBuilderStatus, int expectedEntries)
      Description copied from interface: Type
      Creates the preferred block builder for this type. This is the builder used to store values after an expression projection within the query.

    • getTypeParameters

      public List<Type> getTypeParameters()
      Description copied from interface: Type
      For parameterized types returns the list of parameters.
      Specified by:
      getTypeParameters in interface Type
      Overrides:
      getTypeParameters in class AbstractType

    • getDisplayName

      public String getDisplayName()
      Description copied from interface: Type
      Returns the name of this type that should be displayed to end-users.
      Specified by:
      getDisplayName in interface Type
      Overrides:
      getDisplayName in class AbstractType
